Below, we explore the top regions and our recommended times of year to experience them at their fullest.

Costa Rica’s Highlights

Costa Rica is a land of extraordinary biodiversity, where misty rainforests, river canyons, volcano-shaped skylines, and tranquil Pacific bays converge across dramatically shifting microclimates.

The Osa Peninsula, remote and wild, is one of the country’s most pristine corners. It is defined by dense rainforest, the protected waters of Golfo Dulce, and an astonishing concentration of wildlife, including four species of monkeys, vibrant morpho butterflies, over 400 bird species, dolphins, manta rays, and whales.

The Pacuare Forest is a region of pristine river canyons, towering rainforest, and lush, untouched landscapes. A true playground for adventurers, while also offering opportunities for meaningful cultural immersion with the Cabécar indigenous community, one of Costa Rica’s most traditional and remote groups.

Set along a peaceful stretch of the Pacific coast, the Papagayo Peninsula delivers a mix of natural beauty, privacy, and refined luxury. Calm, warm waters create ideal conditions for kayaking, stand-up paddleboarding, snorkeling, and private sunset catamaran outings.

Dominated by the perfectly conical Arenal Volcano, Arenal blends volcanic drama with rainforest abundance. Here you can enjoy exciting outdoor adventures while admiring sweeping views of tropical mountains, an array of colorful birdlife and lush vegetation.

The Best Time To Visit The Osa Peninsula

The best time to visit the Osa Peninsula is during the dry season, from December to April. During these months, rainfall is at its lowest and wildlife viewing is at its best.

You can expect temperatures to range from 70°F to 90°F, with clear skies and long, sun-filled days that make outdoor exploration especially rewarding.

This is the perfect time of year for to embark on the region’s signature experiences, including hikes through pristine rainforest, horseback rides along jungle trails to secluded Pacific beaches, and night walks that reveal kinkajous, frogs, bats, and other nocturnal wildlife.

Dry season is also one of the best times of year to spot scarlet macaws, dolphins, monkeys, sloths, and brightly colored birdlife in the rainforest canopy.

On the water, calm seas in the Golfo Dulce create perfect conditions for dolphin watching, kayaking, snorkeling, and private boat trips through mangroves to spot turtles, rays, crocodiles, and abundant birdlife. Humpback whales are also commonly seen during their migration.

While you can visit the Osa Peninsula from May through November, you should expect heavier rainfall which can make parts of the peninsula more challenging to access.

The Best Time To Visit The Pacuare Forest

Pacuare Forest is best enjoyed from December to April, as river conditions are at their most stable and the surrounding rainforest is at its most accessible. Visit during these months for a balance of warm temperatures, clear skies, and ideal water levels.

This is the best season to immerse yourself in Pacuare’s dramatic landscapes of emerald mountains, narrow river gorges, hidden waterfalls, and pristine rainforest corridors that shelter an extraordinary range of wildlife.

Between December and April, you’ll find morning mists lift to reveal canopy-fringed cliffs, and afternoons are typically sunny. Whether you’re white-water rafting along the river, exploring secluded jungle trails, or rappelling down waterfalls and canyon walls, the dry season creates optimal conditions for safe, exhilarating adventure.

Throughout the year, you can enjoy cultural encounters with the indigenous Cabécar community. However, trails leading into the Talamanca Mountains, where these families have lived for centuries, are safer and more accessible during dry season.

From May through November, the rainforest shifts into its wet season. The forest becomes lush and atmospheric, but canopy and ground adventures can be weather-dependent, and increased rainfall may lead to muddier trails, limited visibility, and occasional schedule adjustments. River levels also rise, creating stronger, more technical rapids that may appeal to seasoned rafters but can result in modified routes for safety.

The Best Time To Visit The Papagayo Peninsula

Set along Costa Rica’s northwestern Pacific coast, Peninsula Papagayo is a sun-drenched enclave of sheltered bays, golden beaches, and calm turquoise waters, best visited from December through April.

During these months, warm, sunny days of between 75°F to 95°F and gentle seas create perfect conditions for swimming, boating, and exploring the peninsula’s coastline.

You can embark on private sunset catamaran excursions to hidden bays, glide silently over crystal-clear water on inflatable water bikes, or enjoy ocean-view golf on a spectacular local course.

We recommend staying at the Four Seasons, which is beautifully positioned on the peninsula’s narrow stretch of land and bordered by two distinct beaches. While one is serene and ideal for swimming, the other is facing livelier Pacific waters and is perfect for kayaking, paddleboarding, and water sports.

The surrounding tropical dry forest is one of the rarest ecosystems in the Americas, and sets the scene with its wild beauty, home to howler monkeys, vibrant birdlife, and ancient trees that frame unforgettable jungle-meets-ocean vistas.

Many activities can be enjoyed year-round, including a private rum and chocolate tasting with an in-house expert. However, for experiences like a stargazing dinner under Costa Rica’s expansive night skies, when telescopes reveal the Southern Hemisphere’s constellations, December through April is best. The dry season offers clearer skies, lower humidity, and optimal conditions for celestial viewing.

The Best Time To Visit Arenal

Arenal is one of Costa Rica’s most iconic landscapes, with its perfectly conical volcano, lush rainforest, and mineral hot springs. Its beauty also makes it one of the country’s most visited destinations, especially during the peak dry season from December through April.

Crowds are common, and travelers seeking privacy or exclusivity often prefer Costa Rica’s more secluded regions. With thoughtful planning and the right timing, however, it is still possible to enjoy serene, beautiful moments amid the scenery.

From December through April, the weather is dry and sunny, bringing clear views of the volcano and optimal conditions for exploring the outdoors. Mornings tend to be bright and crisp, ideal for scenic hikes or quiet wildlife walks, while warm afternoons are perfect for soaking in the area’s natural hot springs.

During these months, trails leading to lookout points and volcanic formations are easier to navigate, and activities such as gentle birdwatching, relaxed horseback rides to La Fortuna Waterfall, or floating along forested rivers are at their most enjoyable.

It’s also a wonderful time of year to experience Arenal’s famous treetop ziplining, which is best done early in the day when visibility is at its peak.
