Costa Rica’s December Adventure Guide: The Best Outdoor Activities for the Dry Season

Why December Creates the Perfect Conditions for Adventure

December marks the beginning of the dry season in much of Costa Rica, making it one of the best months for outdoor activities. Rivers run strong from the recent rains, beaches enjoy clear and sunny days, and the rainforest looks vibrant after months of moisture. Travelers looking for thrilling experiences or nature focused excursions will find December ideal for exploring the country’s landscapes, wildlife and coastlines.

High Energy Adventures for Thrill Seekers

Zip Line and Canopy Tours Above the Forest

Zip lining is one of Costa Rica’s most iconic activities, and December provides excellent conditions for it. Clear skies and crisp mornings make canopy tours especially scenic. Travelers glide above the treetops, taking in panoramic views of volcanoes, rainforests and valleys.

Rafting on Fast Flowing Rivers

December is one of the best times for white water rafting. Rivers carry the final push of rainy season runoff, creating exciting rapids that remain stable and well managed. Popular rafting destinations include the Pacuare, Sarapiquí and Balsa Rivers, which offer options for both beginners and experienced paddlers.

ATV Riding and Canyoning Adventures

ATV tours are popular in beach towns like Tamarindo and Jaco, where trails lead to lookout points, forests and rural communities. Canyoning offers a more intense experience as travelers rappel down waterfalls, cross streams and climb through natural rock formations.

Surfing on Both Coasts

Costa Rica enjoys consistent surfing in December. The Pacific coast sees steady swells perfect for beginners and intermediates, while the Caribbean can produce powerful waves when weather conditions align. Surf schools welcome new learners during this time, making December ideal for trying the sport.

Nature Experiences That Shine in December

Volcano Hikes with Clear Views

Clear skies make volcano viewing one of December’s highlights. Travelers visiting Arenal, Poas or Rincon de la Vieja enjoy improved visibility, allowing for scenic hikes, crater viewpoints and photography opportunities.

Waterfalls and Hot Springs in Their Best Season

After the green season, waterfalls run strong and look especially impressive. Popular locations include La Fortuna Waterfall, Llanos de Cortez and Montezuma. Hot springs near La Fortuna also feel refreshing during the warm December evenings.

Night Walks for Nocturnal Wildlife

Nighttime rainforest tours reveal a side of Costa Rica that most visitors never experience. Frogs, insects, reptiles and nocturnal mammals become active after sunset. Mild December nights make these tours especially pleasant.

Hanging Bridges for Easy Access to the Canopy

Hanging bridge trails offer breathtaking views of the forest canopy and are accessible for most ages. Monteverde and Arenal are two of the most popular spots for this activity.

Wildlife Encounters During the Early Dry Season

Sloths in the Trees

Sloth sightings are common in December, especially in areas like Manuel Antonio, La Fortuna and the Caribbean coast. Guided tours increase chances of spotting both two toed and three toed sloths.

Monkeys Moving Through the Forest

Species such as howler monkeys, capuchin monkeys and spider monkeys are active during this time. Families often hear their calls echoing through the trees before spotting them overhead.

Birdwatching for Color and Movement

December is excellent for birdwatching. Migratory species visit the country and resident birds display bright plumage. Travelers may see toucans, parrots, hummingbirds and a wide range of rainforest species.

Ocean Adventures Along Costa Rica’s Coastline

Catamaran Cruises with Sunset Views

Catamaran tours are popular along the Pacific coast, especially in Guanacaste. These excursions often include snorkeling stops, open bar options and sunset views over the ocean.

Snorkeling and Scuba Diving

Marine visibility begins improving in December, making it a strong month for underwater activities. Isla del Caño, the Papagayo Peninsula and the southern Pacific coast offer excellent marine life viewing, including turtles, reef fish and rays.

Kayaking Through Bays and Mangroves

Kayaking allows travelers to explore quiet coastlines, mangrove forests and calm bays. December’s light winds create smooth paddling conditions, ideal for both beginners and families.

How to Secure Adventure Activities During Peak Season

December is one of the busiest months for tours, so planning ahead is essential. Booking zip line tours, rafting excursions or guided wildlife hikes before arriving ensures availability and helps avoid long wait times. Many popular attractions offer morning and afternoon departures, giving travelers flexibility in scheduling. For ocean activities, early reservations are recommended since spots can fill quickly on catamarans and dive boats during the holiday period.
