Located on Costa Rica’s stunning Pacific coast, Marino Ballena National Park is a true hidden gem. Famous for its breathtaking beaches, rich marine biodiversity, and the iconic Whale’s Tail formation, this park is a must-visit destination for nature lovers and adventure seekers. Whether you’re here for whale watching in Uvita, snorkeling or simply relaxing on the pristine coastline, Marino Ballena National Park offers an unforgettable experience.
What Makes Marino Ballena National Park Special?
This protected marine park was established in 1989 to preserve the region’s diverse marine life, coral reefs, and mangroves. Covering approximately 110 hectares of land and over 5,000 hectares of ocean, it is home to an incredible variety of species, including humpback whales, dolphins, sea turtles, and tropical fish.
One of the park’s most famous landmarks is the Whale’s Tail, a naturally formed sandbar and reef structure that, at low tide, resembles the shape of a whale’s tail. This unique formation is visible from above and is one of the most photographed spots in Costa Rica.
Best Things to Do in Marino Ballena National Park
1. Whale Watching in Uvita
Marino Ballena National Park is one of the best places in the world for whale watching. Every year, humpback whales migrate to these warm waters to breed and give birth. Visitors have a chance to see these magnificent creatures from July to November (Southern Hemisphere whales) and again from December to April (Northern Hemisphere whales).
Whale watching tours in Uvita offer an unforgettable experience, allowing you to witness breaching whales, playful dolphins, and other marine wildlife in their natural habitat.

2. Snorkeling and Marine Life Exploration
While snorkeling in Marino Ballena National Park is possible, it may not be the best choice for those looking for a truly spectacular underwater experience. The park’s waters are home to some coral formations, tropical fish, and occasional sea turtles, but visibility can be inconsistent, especially during the rainy season or after strong tides. The best snorkeling spots, such as the Whale’s Tail reef and Ballena Island, offer a glimpse into Costa Rica’s marine life, but they don’t compare to other top snorkeling destinations in the country.
For the best snorkeling near Uvita, consider visiting Isla del Caño, located just 50 minutes away by boat. This protected biological reserve offers crystal-clear waters, thriving coral reefs, and a much higher diversity of marine life, including reef sharks, manta rays, and large schools of tropical fish. If snorkeling is a priority during your trip, booking a tour to Isla del Caño is highly recommended for a truly world-class underwater experience.
3. Relaxing on Uvita Beach
Uvita Beach is one of the most beautiful and peaceful beaches in Costa Rica. With its golden sand, calm waters, and scenic views, it’s an ideal place to relax, sunbathe, or enjoy a peaceful walk along the shore. The lack of large crowds makes it one of the best hidden beaches in Costa Rica.
4. Hiking and Wildlife Spotting
Although Marino Ballena National Park is mostly known for its marine attractions, it also offers opportunities for hiking and exploring coastal rainforests. Trails within the park lead to secluded beaches, mangrove forests, and scenic viewpoints where you can spot howler monkeys, iguanas, scarlet macaws, and other exotic wildlife.
