National Parks

Costa Rica experiences a preferred climate that is perfect for making lush vegetation thrive and providing every visitor with outstanding landscapes. That’s why visiting at least one of the many national parks in Costa Rica is a must for nature lovers.

Manuel Antonio National Park

Manuel Antonio National Park, a crown jewel among Costa Rican tourist destinations, teems with wildlife, including monkeys, sloths, iguanas, snakes, and an astonishing diversity of over 1,000 bird species.

When you visit the park, you can choose between wandering through its hiking trails or visiting the region’s top-rated beaches like Escondido, Manuel Antonio, and Playa Espadilla Sur.

In this verdant ecosystem, you can also find numerous marine species, including moray eels, angelfish, and starfish.

Arenal Volcano National Park

Arenal Volcano National Park is a favorite among local and international tourists, boasting many outdoor activities amidst stunning landscapes.

Its most iconic feature, the Arenal Volcano, presents a perfectly symmetrical silhouette. Other park attractions extend beyond the volcano in the La Fortuna district. There’s the expansive Lake Arenal, the refreshing La Fortuna Waterfall and Rio Celeste, and the renowned Tabacón Hot Springs.

Corcovado National Park

Corcovado National Park, situated on the remote Osa Peninsula in Costa Rica, is a biodiversity hotspot. The park protects rainforests, mangroves, beaches, and marine habitats. As a result of this diversity, wildlife enthusiasts can observe exotic creatures in their natural habitats.

Trails extend across the park’s vast natural surroundings, making it a hiking paradise. There’s nothing like a hike through the park with the Pacific Ocean as a stunning backdrop.

Tamarindo Beach

Tamarindo Beach is a popular destination in Guanacaste Province with its golden sand and clear waters. This beach resort offers everything from surfing and snorkeling to horseback riding and zip-lining. 

After the sun sets, Tamarindo comes alive with an energetic nightlife scene. Watch the sunset over the Pacific Ocean while listening to live music and enjoying delicious drinks.

Playa Grande

North of Tamarindo lies Playa Grande, part of Marino Las Baulas National Park and a nesting site for endangered leatherback turtles.

In addition to its serene atmosphere, this beach is renowned for its excellent surf breaks, which are suitable for all levels of surfers. A vast expanse of sandy beach and verdant coastal vegetation provide a peaceful setting for strolls and sunbathing away from the usual tourist crowds.

Playa Matapalo

Playa Matapalo, located in Puntarenas, is an idyllic spot for those seeking tranquility. The uncrowded sands extend into the clear Pacific waters, making it an excellent location for sunbathing, swimming, and shell-collecting.

How crowded are tourist attractions in Costa Rica during December?

December in Costa Rica marks the peak travel season. Local and foreign tourists flock to popular destinations throughout the country.

Other regions in Costa Rica also experience higher prices and more crowds during the country’s dry season. However, the vibrant atmosphere and splendid weather make visiting during the peak season highly rewarding.
