Visas & entry
Most visitors from the US, Canada, UK, EU, Australia and many Latin American countries can enter Costa Rica visa-free as tourists, typically for up to 180 days at the immigration officer’s discretion. You need a passport valid for your stay and are commonly asked for onward travel and proof of funds; confirm rules for your nationality before departure.
Getting in
- Juan Santamaría International Airport / Alajuela: The default gateway for almost every first visit. Sleep near the airport after a late arrival, use it for Alajuela, Poás and the coffee highlands, then drive or transfer north to La Fortuna; do not plan a same-night mountain transfer after a long flight.
- Daniel Oduber Quirós International Airport / Liberia: A useful alternate for Bijagua–Río Celeste and the province’s northwest edge, especially when flight prices or schedules are better than SJO. It is less logical than SJO for Poás, Alajuela city and the Central Valley.
- La Fortuna / Arenal Airport: A small domestic-airstrip option for travelers connecting from San José when time matters more than cost. Treat it as a limited scheduled-flight and charter gateway, not a substitute for SJO; weather and baggage limits can matter.
Getting around
Renting a car is the practical choice for a multi-stop Alajuela trip: it makes La Fortuna, Bijagua/Río Celeste, Caño Negro and the highlands workable at a sane pace. Drive only in daylight on upland and rural roads; rain, fog, trucks, potholes and slow mountain routes make map times optimistic. Tourist shuttles and buses can cover SJO/Alajuela–La Fortuna, but once you add Bijagua or Caño Negro, public transport turns a short trip into a fragile, slow two-base itinerary rather than a flexible loop. There is no useful intercity rail network for this route.
Money
The currency is the Costa Rican colón (CRC), though US dollars are widely accepted in La Fortuna and other tourism businesses; cards work well for hotels, parks and larger restaurants. Carry colones and small bills for sodas, rural shops, taxis and tips. Restaurant and hotel bills normally already include 13% VAT and a 10% service charge, so additional tipping is optional for notably good service.

- Ranges exclude international flights. They assume shared accommodation and transport where relevant; a solo rental car materially raises the value budget.
- Value: hostel or simple guesthouse, sodas, public bus/shared shuttle, and one modest paid activity every day or two.
- Comfortable mid-range: private room or good small lodge, shared rental car or tourist shuttle, restaurant meals, a paid activity most days and one mid-priced hot-spring visit.
- High-end: luxury rainforest lodge, private transfers, premium hot springs/spa, private guides and upscale dining.
- La Fortuna is the province’s budget escalator: room rates, car insurance, private transfers, hot-spring passes and commercial adventure activities drive costs far more than national parks.
- Spend selectively in Arenal. Pick one or two activities you actually care about rather than buying a bundled volcano/waterfall/bridges/hot-springs itinerary every day. National parks are comparatively cheap; commercial attractions are not. Restaurant and hotel bills normally include 13% VAT and a 10% service charge.
Eating well
- Use La Fortuna for convenience, not culinary discovery; its restaurant scene is broad but heavily tourism-oriented.
- Make dairy and bakery stops part of road-trip days through San Carlos and the cooler Central Valley rather than saving food exploration for dinner.
- Sodas are the sensible choice for inexpensive, traditional lunches; restaurant and hotel bills normally include 13% VAT and a 10% service charge.
Book before you land
Poás Volcano National Park timed entry reservation · Tenorio Volcano National Park / Río Celeste official entry ticket
- Use Alajuela/SJO for the arrival or departure night, La Fortuna for 3–5 nights, then move to Bijagua or Caño Negro if those are priorities. Do not try to day-trip the entire province from one hotel.
- Book Poás and Río Celeste through official park channels. Poás can close or restrict access for volcanic gas, wind or cloud; a reservation guarantees entry only when conditions permit, not a crater view.
- At Río Celeste, daily entry and trail numbers are capped. Go early, allow roughly three hours for the 6 km return trail, and expect the water color to be less dramatic after heavy rain.
- Pack for two climates: a fleece and waterproof layer for Poás and Bajos del Toro, plus quick-dry clothes, sun protection and insect repellent for La Fortuna, San Carlos and Caño Negro.
- Arenal’s commercial attractions can cost far more than national parks. Pick one or two paid splurges—such as hot springs, rafting or hanging bridges—rather than buying an activity package every day.
- For remote waterfall roads, Bijagua, Caño Negro and any mountain transfer, keep driving to daylight and leave weather buffer before an international flight.

Season by season
January-February
Usually the driest, most road-trip-friendly stretch, with clearer early volcano mornings, but Arenal can still be rainy or clouded and La Fortuna rooms are in high demand.
first visitsself-drivingvolcano morningsoutdoor adventure
Peak prices and crowds; reserve La Fortuna lodging, better hot springs and transfers well ahead.
March-April
Generally dry and hot in the northern lowlands, making hiking and driving straightforward, though major sights around La Fortuna, Poás and Río Celeste are busy.
hikingrental-car loopsfamiliesvolcano and waterfall trips
Semana Santa can make cars, rooms and restaurants scarce, while April heat is strongest in San Carlos and the wetlands.
May-June
The green season brings lush forest, full waterfalls and usually more usable mornings before afternoon rain, though upland weather remains unpredictable.

Cloud can erase volcano views and wet, remote roads—especially around Bajos del Toro—need more caution.
July-August
A relative mid-year rain break sometimes appears in July, but it is not dependable around Arenal, Poás or Bajos del Toro; landscapes remain intensely green.

School-holiday demand can fill family-friendly La Fortuna hotels and popular adventure operators despite the nominal low season.
September-October
Often the wettest-feeling, quietest period, with swollen rivers, slippery trails, frequent cloud and a higher chance of weather-disrupted transfers.

Poor choice if the trip depends on daily Arenal cone views, clear Poás crater conditions or tightly timed waterfall excursions.
November
Rain often starts easing while the landscape stays green and prices remain below high-season levels, making this a strong flexible self-drive month.

Events worth planning around
Fiestas de Palmares · Usually January · Palmares, western Central Valley
A major local fair with concerts, horse parades, food and carnival energy; it brings heavy local traffic and lodging demand, so stay nearby only if the party is part of the plan.
Semana Santa / Holy Week · Moveable; usually March or April · Province-wide, especially roads and domestic-tourism hubs
Costa Rican domestic travel surges; reserve rental cars, lodging and transfers early, and expect some smaller businesses to alter hours.
Expo San Carlos · Usually April · Ciudad Quesada / San Carlos
A substantial agricultural and cattle fair worth seeking out for regional culture, but it raises demand and traffic around San Carlos.
What to eat
Eat for the province’s working landscape rather than for a separate regional cuisine: coffee-country breakfasts and lunches in the Central Valley, then fresh dairy in San Carlos. Seek out queso palmito, stop at rural bakeries and dairy counters on driving days, and use sodas for straightforward beans, plantain, pork and fruit rather than treating La Fortuna’s international restaurant strip as the food destination.
