The 7-Day Costa Rica Itinerary: The Health-Smart Version

In my practice, the travelers who come back from Costa Rica with a story they did not want are rarely tripped up by anything tropical and rare. They are tripped up by four ordinary things: a stomach bug from food or water, a day-biting mosquito carrying dengue, a Pacific rip current, and an adventure activity that went slightly wrong. The reassuring part is that the classic first-timer loop, San Jose to Arenal to Monteverde to Manuel Antonio, is logistically smooth and medically low-stakes if you prepare for those four. Traveler's diarrhea is still the most common travel illness, dengue is endemic and peaks in the rainy season, and the Pacific coast delivers strong sun and stronger surf. Two to three weeks before you fly, sort hepatitis A and typhoid plus a traveler's diarrhea prescription, pack an all-day mosquito strategy, and plan for winding roads and ocean days. Do that, and the seven days below run smoothly.

This is a genuine day-by-day plan, not a generic list with a health paragraph stapled to the end. The route, the Central Valley up to the Arenal volcano, across to the Monteverde cloud forest, and down to the central Pacific coast, is the standard one-week loop, and the health prep is built into where you eat, what you pack, and how you pace each leg.

Why food, mosquitoes, surf, and adventure, not altitude, drive your Costa Rica plan

Costa Rica is small, green, and warm, and most of the classic route sits at low to moderate elevation. San Jose and the Central Valley are around 1,150 meters, Monteverde sits near 1,400 meters, and the Pacific coast is at sea level. None of that is true altitude, so acetazolamide and acclimatization, the headline of an Andes or Kilimanjaro trip, simply do not apply here. The brief exceptions are the day trips to the Poas and Irazu volcano summits, which reach roughly 2,700 to 3,400 meters, but you are there for an hour or two, not sleeping, so altitude illness is uncommon.

What actually shapes a Costa Rica trip is the everyday risk profile of the tropics. Traveler's diarrhea remains the single most common travel illness worldwide, and while Costa Rica's tap water is generally treated and drinkable in San Jose and the main tourist areas, food and water caution still matters, especially in rural lodges and on the coast. Dengue, carried by the day-biting Aedes mosquito, is endemic countrywide and surges during and after the rainy season, which runs roughly May through November, with the highest case counts in the lowland coastal provinces of Guanacaste, Puntarenas, and Limon. Add the intense Pacific sun, the rip currents that make ocean safety the most underrated risk on the trip, and the ziplines, rafts, ATVs, and trails that draw people here in the first place, and you have the real list. None of it should scare you off. It should shape your packing and your habits, which is exactly what the itinerary below does.

The pre-trip health timeline (start this 4 to 6 weeks out)

Your Costa Rica trip really begins before departure. Four to six weeks out, confirm your routine vaccines are current and ask a clinician about hepatitis A and typhoid, both of which the CDC recommends for most travelers to Costa Rica because of food and waterborne risk. Depending on your plans and history, a clinician may also discuss rabies, which is relevant mainly if you will spend time around stray dogs, bats, or remote areas far from medical care.

One entry-requirement note that trips people up: Costa Rica does not require yellow fever vaccination for travelers arriving directly from the United States. It only requires proof of yellow fever vaccination if you are arriving from, or have recently transited, a country with risk of yellow fever transmission, which includes parts of sub-Saharan Africa and tropical South America. If Costa Rica is part of a multi-country trip, check this early, because a missing certificate can mean problems at the border.

Two to three weeks out, handle prescriptions. The one that matters most for nearly every Costa Rica traveler is a traveler's diarrhea plan: an antibiotic the clinician selects plus loperamide for symptom control. Malaria is the common question, and for the standard San Jose, Arenal, Monteverde, and central Pacific route the answer is no pills needed. Malaria risk in Costa Rica is very low and limited to specific rural areas, and the CDC has not recommended routine antimalarials for typical tourist itineraries; the agency even removed its earlier malaria travel notice for the country. If your trip pushes into rural parts of the northern zone near the Nicaragua border or the Limon province lowlands, it is worth a clinician's eyes on your specific route, but the classic loop does not call for malaria pills.

Here is how the two Wandr workflows differ, because they are not the same. For prescription medications like a traveler's diarrhea antibiotic or motion sickness medication, Wandr's clinicians review your exact Costa Rica plan and call any needed prescriptions in to your local pharmacy for pickup, so you are not hunting for a travel clinic the week before departure. For vaccines like hepatitis A and typhoid, Wandr books your appointment at a partner pharmacy near you and the pharmacist administers them on-site, no separate doctor's visit required. Start with the free pre-trip health check to see what your route actually requires.

Day 1: Arrive in San Jose

Most flights from the US land in San Jose (SJO) in the afternoon or evening, so treat Day 1 as a soft landing rather than a sightseeing sprint. The Central Valley is mild and pleasant, a relief if you are coming from a heat wave back home, and the modest elevation is nothing your body needs to adjust to. Hydrate, settle in, and resist the urge to schedule a big first morning.

If you have a spare half-day in the capital, the Pre-Columbian Gold Museum, the National Theatre, and the Central Market make for an easy, low-effort introduction. The main health task today is simple: rest after the travel day, drink more water than feels necessary, and do a final check of your kit, repellent, sunscreen, your traveler's diarrhea prescription, and any motion sickness medication, before the early start tomorrow.

Days 2-3: La Fortuna and Arenal Volcano

On Day 2, transfer about three hours northwest to La Fortuna, the small town at the base of the iconic cone of Arenal Volcano. This is the adventure heart of the trip: hanging bridges through the rainforest canopy, the La Fortuna Waterfall, volcanic hot springs in the evening, and a menu of ziplining, white-water rafting, canyoning, and ATV tours.

This is where the trip's most underappreciated risk lives, and it is not an infection. It is injury. Adventure activities are wonderful, and they are also the most common reason travelers end up in a clinic here. The fixes are unglamorous and effective: use reputable, well-reviewed operators, wear the helmet and harness they give you, listen to the safety briefing, and do not attempt rafting class or a canyoning route beyond your fitness and experience. Hydrate through the day, because the humidity hides how much you are sweating, and watch your footing on wet trails and bridges. If a bad meal catches up with you, this is where your prescription earns its place: for moderate to severe traveler's diarrhea, a short antibiotic course plus loperamide can shorten illness from several days to roughly one, according to clinical guidelines. Carry both so a single meal does not cost you a travel day. For the full playbook, see our traveler's diarrhea guide.

Day 3 is for the slower Arenal pleasures: the national park trails with volcano views, a coffee or chocolate tour, and the hot springs to finish. One practical note on the springs, the heat plus a drink plus a long humid day is exactly the combination that leaves people lightheaded, so go easy, alternate with water, and step out to cool down if you feel woozy.

Day 4: The jeep-boat-jeep to Monteverde

Day 4 is a transition day, and it is the one most itineraries treat as a simple transfer when it is actually a motion-sickness day. The classic route from Arenal to Monteverde is the "jeep-boat-jeep," a van to the shore of Lake Arenal, a boat across the lake, and a van up the other side on winding, often unpaved mountain roads. The lake crossing and the twisting climb can both turn a queasy stomach against you.

If you are at all prone to motion sickness, plan ahead rather than hoping for the best. Options range from over-the-counter antihistamines like dimenhydrinate or meclizine to a prescription scopolamine patch for longer or rougher days. Take the first dose before you set out, not after symptoms start, because these medications work far better as prevention than as a rescue. Our motion sickness guide covers what to use and when. Sit forward, look at the horizon on the boat, and keep water and a few plain snacks within reach.

Day 5: Monteverde Cloud Forest

Monteverde is the cool, misty counterpoint to the lowlands: a cloud forest draped in moss and orchids, alive with birds and, if you are lucky, a resplendent quetzal. The signature experiences are the hanging-bridge canopy walks, the longest and highest ziplines in the country, guided nature walks, and a night walk to spot frogs, snakes, and sleeping wildlife.

At around 1,400 meters, Monteverde is cooler and often damp, so the health notes here are different from the coast. Bring a light rain layer and warmer clothing than people expect for "tropical" Costa Rica, because being wet and cold at elevation is its own kind of miserable. The terrain is the main hazard: trails and bridges are slick, so wear real footwear with grip and slow down on the wet sections. Ziplining is once again a use-a-reputable-operator-and-wear-the-gear situation. Mosquito pressure is lower at this elevation than on the coast, but keep your repellent in the bag, because you are heading back down to dengue country tomorrow.

Days 6-7: Manuel Antonio and the Pacific coast

On Day 6, descend roughly three to four hours to the central Pacific coast and Manuel Antonio, where rainforest spills right onto the beach and white-faced capuchins and sloths share the canopy with you. The national park, the beaches, and the warm ocean are the reward at the end of the loop, and Day 7 is for slowing down before you head back to San Jose to fly home.

Two health themes shape the coast. First, this is prime dengue and Zika territory, and the lowland Pacific is warm and, in the wet season, mosquito-heavy. Aedes mosquitoes bite during daylight, so use an EPA-registered repellent through the day, not just in the evening; more on the specifics in the dengue section below. If you are pregnant or planning pregnancy, Zika deserves a specific conversation with your clinician before you book, and our Zika guide walks through why. Second, the ocean is the most underrated risk of the whole trip. The Pacific here has strong rip currents, and drowning is a leading cause of death for travelers worldwide, far more common than any tropical infection. Swim only at beaches where conditions are calm, never swim drunk or alone, and if you are caught in a current, swim parallel to shore rather than fighting straight back in. Add the sun, which at this latitude is stronger than most US travelers expect, so use a high-SPF reef-safe sunscreen, reapply after swimming, and take shade through the midday hours. Our heat illness guide covers when ordinary discomfort tips into something that needs care.

A note for travelers tweaking this route: many people swap Manuel Antonio for the Guanacaste beaches in the northwest or add the Caribbean side near Puerto Viejo. Both are lovely, and both are also lowland coastal areas, so the same dengue, sun, and surf rules carry over without change.

Dengue: the symptoms that should change your plans

Most dengue is a miserable but self-limiting week. The job is recognizing it and avoiding the one dangerous mistake. Dengue typically starts 4 to 7 days after a bite with sudden high fever, severe headache, pain behind the eyes, and deep muscle and joint aches, the reason it earned the nickname "breakbone fever." There is no specific cure; care is rest, fluids, and fever control. Prevention is entirely about bite avoidance, because there is no pill that prevents it: use an EPA-registered repellent (DEET 20 to 30 percent, or picaridin 20 percent) through the day, treat clothing with permethrin before you pack, and favor air-conditioned or screened rooms on the coast. Our insect repellent guide breaks down what to buy and how to layer it.

Here is the part that matters most: if you develop a fever in or after Costa Rica, use acetaminophen (paracetamol), not ibuprofen, aspirin, or other NSAIDs, because those can increase bleeding risk if the illness is dengue. Warning signs that warrant urgent medical care include severe abdominal pain, persistent vomiting, bleeding from the gums or nose, or a fever that worsens around the time it should be breaking. A good rule for travelers: any fever during or within two weeks of a trip to Costa Rica gets evaluated, and you mention the travel history every time. For the complete picture, read our dengue guide.

What this itinerary deliberately gets right

Compared with the typical Costa Rica plan you will find online, this version makes a few health-driven choices on purpose. It treats Day 1 as a recovery day rather than a packed sightseeing day. It plans for motion sickness before the jeep-boat-jeep to Monteverde instead of improvising once the van is climbing. It carries a traveler's diarrhea prescription from home so a single meal does not derail the trip. It frames mosquito protection as an all-day habit because dengue's mosquito bites in daylight, not just at dusk. It respects the Pacific surf as the genuine hazard it is. And it front-loads the vaccine and prescription work weeks before departure instead of scrambling in a San Jose pharmacy. None of this costs you a single volcano, bridge, beach, or sloth. It simply orders the seven days so your body keeps up. If you are still choosing dates, our guide to the best time to visit Costa Rica lays out how the dry and rainy seasons change the health picture.

For vaccines like hepatitis A and typhoid, Wandr books your appointment at a partner pharmacy near you. For prescription medications like a traveler's diarrhea kit and any motion sickness medication, our clinicians match them to this exact route and call them in to your local pharmacy for pickup. Sort your Costa Rica travel medications before you fly, and pair this plan with our full Costa Rica travel health guide for the medical detail behind every leg.

Frequently asked questions

How many days do you need for a Costa Rica itinerary? Seven days is the sweet spot for a first-timer loop: a recovery day in San Jose, two days at Arenal and La Fortuna, a transfer day plus a full day in Monteverde, and two days on the central Pacific coast at Manuel Antonio, ending back in San Jose to fly home. Ten days to two weeks lets you add Guanacaste, the Caribbean side, or a slower pace, but a well-sequenced week covers the headline volcano, cloud forest, and beach comfortably.

Do I need malaria pills for Costa Rica? For the standard San Jose, Arenal, Monteverde, and central Pacific route, malaria pills are not needed. Malaria risk in Costa Rica is very low and limited to specific rural areas, and the CDC does not recommend routine antimalarials for typical tourist itineraries. If your trip includes rural parts of the northern zone near the Nicaragua border or the Limon lowlands, confirm your specific route with a clinician.

What vaccines do I need for Costa Rica? The CDC recommends being up to date on routine vaccines plus hepatitis A and typhoid for most travelers to Costa Rica because of food and waterborne risk. Yellow fever vaccination is not required for travelers arriving directly from the United States; it is only required if you are arriving from a country with risk of yellow fever transmission. Depending on your plans, a clinician may also discuss rabies. Confirm your specific needs before you travel.

Is the tap water safe to drink in Costa Rica? Tap water is generally treated and considered drinkable in San Jose and the main tourist areas. In rural lodges, remote regions, and some coastal areas, water quality is less consistent, so bottled or filtered water is the safer default there. Either way, carrying a traveler's diarrhea prescription is smart, because food, not just water, is the more common source of illness.

Is dengue a serious risk in Costa Rica? Dengue is endemic throughout Costa Rica, with transmission peaking during the rainy season, roughly May through November, and the highest case counts in the lowland coastal provinces of Guanacaste, Puntarenas, and Limon. Most cases resolve with rest and fluids, but bite prevention is essential because there is no specific treatment. Use day-long mosquito protection, since the Aedes mosquito bites during daylight.

Do I need altitude medication for Costa Rica? No. The classic route stays at low to moderate elevation, with Monteverde around 1,400 meters and the Central Valley around 1,150 meters, neither of which causes altitude illness. The Poas and Irazu volcano summits reach higher, but you visit for only an hour or two, so acetazolamide is not part of a standard Costa Rica plan.

What is the most common health problem on a Costa Rica trip? The two to watch are traveler's diarrhea and adventure or ocean injuries. Traveler's diarrhea is the most common illness and is largely preventable with food and water caution plus a prescription antibiotic and loperamide for a bad case. Injuries from ziplining, rafting, ATVs, and especially Pacific rip currents are the most common serious problems, and they are reduced by using reputable operators, wearing the gear, and respecting ocean conditions.

Can I get my Costa Rica prescriptions before the trip? Yes. Wandr's clinicians review your itinerary and call prescriptions in to your local pharmacy for pickup, so you carry your traveler's diarrhea kit and any motion sickness medication from home rather than searching for a pharmacy in San Jose. Start with the free pre-trip health check to see what your route requires.
