Costa Rica has one of the most remarkable ecosystems on earth. A country slightly smaller than West Virginia contains more than 500,000 species — roughly 4% of all species estimated to exist on the planet — packed into cloud forests, rainforests, mangroves, coral reefs, and volcanic highlands. The biodiversity is not just a statistic: sloths hang in the trees above your breakfast table at the eco-lodge, toucans land on the railing, howler monkeys wake you up at dawn, and sea turtles nest on beaches you can walk to from your room. It is an extraordinary place, and it consistently delivers on every element of the promise.
When to Go
Costa Rica has two distinct seasons — the dry season (December through April, called summer locally) and the green season (May through November, called winter). The dry season is the most popular for tourism — reliable sunshine, lower humidity, and easier road conditions. The green season brings daily afternoon rain (typically 1–3 hours, then clearing), more dramatic waterfalls, lush green landscapes, lower prices, and fewer tourists. Many experienced Costa Rica travelers prefer the green season for the atmosphere and value.
The two coasts have different microclimates — when the Pacific coast (Manuel Antonio, Tamarindo, Santa Teresa) is in dry season, the Caribbean coast (Puerto Viejo) may still be rainy, and vice versa. The central valley around San José is generally moderate year-round.
Where to Go
Arenal Volcano and La Fortuna
Arenal is one of the most active volcanoes in the Americas and the anchor experience for most first-time Costa Rica visitors. The perfectly conical volcano (when not shrouded in cloud) rising above Lake Arenal is one of the country's iconic images. The area around La Fortuna town has excellent hot springs — Baldi and Tabacon are the most developed, with multiple pools at different temperatures fed by the geothermal heat of the volcano. White-water rafting on the Sarapiqui River, zip-lining through the cloud forest, hanging bridge walks, and lake kayaking are all accessible from La Fortuna.
Monteverde Cloud Forest
Monteverde is one of the most important cloud forest reserves in the world — a highland ecosystem perpetually wrapped in mist that supports extraordinary biodiversity, including the resplendent quetzal (one of the most beautiful birds in the world, found only in cloud forest). The Monteverde Cloud Forest Reserve and the adjacent Santa Elena Reserve have excellent trail systems. The original zip-line in Costa Rica was built here — the canopy tours remain among the most dramatic in the country. The road to Monteverde is famously rough — plan extra time and consider the quality of your rental vehicle.
Manuel Antonio
Manuel Antonio National Park on the Pacific coast is the most visited park in Costa Rica for the combination of wildlife and beaches — white-faced capuchin monkeys, three-toed sloths, and coatis are all regularly seen from the park trails, which then open onto some of the most beautiful beaches in the country. The town of Manuel Antonio above the park has excellent restaurants and accommodation. The park has a daily visitor limit and sells out — book entry tickets in advance.
The Osa Peninsula
The Osa Peninsula in the far south is the most biodiverse region in Costa Rica — National Geographic has called it one of the most biologically intense places on earth. Corcovado National Park, which covers much of the peninsula, has scarlet macaws, tapirs, jaguar (rare but present), all four monkey species found in Costa Rica, and sea turtles nesting on the beaches. Access is remote — small charter flights or a long drive on rough roads — and accommodation is limited. For travelers who want the deepest rainforest experience in Costa Rica, the Osa is the destination.
The Caribbean Coast
Puerto Viejo de Talamanca in the southern Caribbean has a completely different energy from the Pacific side — a laid-back Afro-Caribbean culture, different cuisine (rice and beans cooked in coconut milk, fresh seafood), reggae music, and some of Costa Rica's best snorkeling and diving at Cahuita National Park's coral reef. The beaches at Punta Uva and Playa Chiquita are extraordinary and largely uncrowded.
Guanacaste
The Pacific northwest province of Guanacaste is Costa Rica's driest region and its main resort area — Tamarindo, Playa Flamingo, Nosara, and Samara are all here. The beaches are excellent, the surf culture is real (particularly around Tamarindo and Playa Grande), and the infrastructure is the most developed in Costa Rica for resort-style travel. Papagayo Peninsula has several large luxury resorts. The Rincon de la Vieja volcano and Palo Verde National Park are inland highlights.
Activities Worth Prioritizing
- Zip-lining: Costa Rica invented commercial zip-lining and still does it better than almost anywhere. Monteverde, Arenal, and Manuel Antonio all have excellent operators.
- White-water rafting: The Pacuare River is consistently rated one of the top 10 white-water rivers in the world — a two-day rafting trip with overnight camping on the river is one of the best adventure experiences in Central America.
- Sea turtle nesting: Tortuguero National Park on the Caribbean coast (July through October for green turtles) and Ostional on the Pacific coast (olive ridley arrivals) both offer night tours to watch sea turtles nest — a genuinely moving experience.
- Surfing: Tamarindo, Jaco, Playa Hermosa, and Dominical all have consistent surf and excellent surf schools for beginners.
- Night tours: A guided night tour in any rainforest area reveals the extraordinary nocturnal wildlife that is invisible during the day — red-eyed tree frogs, kinkajous, sleeping birds, insects, and sometimes snakes.

What Women Should Pack for Costa Rica
Costa Rica is a performance and adventure destination that also has beach and resort elements — the wardrobe needs to cover both, with a bias toward practical over stylish.
For active days: quick-dry shorts and lightweight hiking pants that handle trail conditions. Moisture-wicking tops and long-sleeve sun protection layers for exposed hikes and boat trips. A lightweight waterproof rain jacket — in the green season this is essential; even in dry season the cloud forest and waterfall areas are wet. Waterproof trail shoes or hiking boots for jungle trails — trails can be muddy and wet regardless of season.
For beach and resort time: 2–3 swimsuits. Lightweight casual dresses and cover-ups. Sandals for the beach and casual evenings.
For evenings at eco-lodges and restaurants: a comfortable casual dress or a clean top with linen pants. Eco-lodges in Costa Rica are relaxed in dress code — the wildlife viewing at the dinner table is the entertainment, not the formality.
A day pack for excursions — it needs to carry water (at least 2 liters), sunscreen, rain jacket, camera, snacks, and insect repellent. A small crossbody for towns and restaurants.
What Men Should Pack for Costa Rica
Quick-dry shorts and lightweight hiking pants. Moisture-wicking shirts for active days. A waterproof jacket. 2–3 swim trunks. Waterproof trail shoes or hiking boots for jungle days. Sandals for beach and resort time. A day pack sized appropriately for full-day excursions.
Practical Notes
- Pura Vida: The national phrase and philosophy — pure life, good vibes, everything is fine. It is not just a marketing slogan. The Costa Rican approach to life genuinely reflects it, and travelers who adopt it have better experiences than those fighting the inevitable delays and changes of rainforest travel.
- Rental cars: Essential for independent exploration. Book in advance, get a 4WD (the roads require it in many areas), and purchase local insurance even if your credit card provides some coverage — the road conditions create situations your home insurance does not anticipate.
- Wildlife watching tips: Early morning (6–8am) and late afternoon (4–6pm) are the most active times for most wildlife. Move slowly and quietly. Listen for movement before looking. A knowledgeable guide dramatically improves the number and variety of sightings.
- Currency: Costa Rican colón. US dollars are accepted virtually everywhere. Cards widely accepted in tourist areas.
- Vaccinations: No vaccinations required but yellow fever certificate required if arriving from a yellow fever endemic country. Hepatitis A, typhoid, and tetanus recommended — consult a travel health provider.
Costa Rica changes people in small ways. Spending time in an environment where extraordinary wildlife is an ordinary part of daily life recalibrates something about what feels important. Go prepared, move slowly, and pay attention to what is happening in the trees.
