Marino Ballena National Park is just minutes from our dive center in Uvita, making it one of the most accessible snorkeling spots on Costa Rica’s Pacific coast. This half-day trip works great for families, beginners, or anyone who wants to explore vibrant coral reefs without spending the whole day at sea. We visit spots like Whale Rock, Ballena Island, and the Three Sisters, where colorful fish dart between coral formations and sea turtles glide through the clear water.
The boat ride from Uvita beach takes only 10-15 minutes, so you spend more time in the water and less time getting there. I often suggest this tour to guests staying in the area who have a free morning, or to those who want to try snorkeling before deciding on a full-day trip to Caño Island.
Costa Rica created Marino Ballena as its first marine national park back in 1990, and the results speak for themselves. The reef system here hosts 18 different coral species and over 80 marine species, all thriving thanks to more than three decades of protection. You can expect to see parrotfish, butterflyfish, blue tangs, moray eels, and if you are lucky, a hawksbill turtle cruising past.
The park protects over 5,300 hectares of ocean, including the famous Whale’s Tail sandbar that inspired the park’s name. Between snorkeling sessions, you can spot this natural formation stretching into the Pacific. Humpback whales migrate through these waters twice a year, and while they stay at the surface, hearing their distant songs while floating in the warm water adds something magical to the experience.

Visibility at Marino Ballena ranges from 20 to 50 feet during the dry season, with the clearest water typically from January through April. The ocean stays warm all year, between 78°F and 84°F, so most snorkelers feel comfortable in just a swimsuit or a thin rashguard for sun protection.
The snorkeling sites here are shallow, usually between 3 and 10 feet deep, which makes them perfect for beginners and families with kids. You can float right above the coral formations and watch the action unfold below without needing to dive down.
Sea turtles are the stars of the show here. Hawksbills and olive ridleys feed on sponges and algae growing on the rocks, and they tend to ignore snorkelers who keep a respectful distance. Watching a turtle munch on coral just a few feet away is one of those moments that sticks with you.
Colorful reef fish are everywhere. Parrotfish crunch on coral, butterflyfish flutter between formations, and blue tangs school together in bright clouds. Look closer at the rocks and you will spot pufferfish, moray eels peeking from holes, and the occasional octopus blending into its surroundings.
During whale season (July through November and December through April), humpback whales visit Marino Ballena to give birth and nurse their calves. You might spot them breaching from the boat between snorkeling stops, and if you are really lucky, you will hear their songs carrying through the water while you float at the surface.
Marino Ballena National Park sits right at our doorstep in Uvita, making it the most accessible snorkeling destination on Costa Rica’s southern Pacific coast. The boat ride takes just 10 to 15 minutes from the beach, which means more time exploring the reef and less time getting there. For families and first-time snorkelers, this short journey removes the stress of long open-water crossings and seasickness concerns.
The snorkeling sites within the park deliver a surprisingly rich underwater experience for a coastal location. Visibility ranges from 20 to 50 feet during dry season, with shallow reefs sitting just 3 to 10 feet below the surface. Sea turtles are the highlight here. Hawksbills and olive ridleys feed calmly on sponges and algae, often allowing snorkelers to watch from just a few feet away. Parrotfish crunch on coral, butterflyfish flutter between formations, and blue tangs school together in bright clouds that seem to shimmer in the sunlight.
Choosing Marino Ballena makes sense for travelers who want a taste of Costa Rica’s underwater world without committing to a full-day expedition. The tour wraps up by late morning, leaving the entire afternoon free to walk the famous Whale’s Tail sandbar, chase waterfalls near Uvita, or simply relax at your hotel. It works perfectly as a warm-up before tackling the longer Caño Island trip, or as a standalone adventure for visitors with limited time.
The intimate group sizes on our Marino Ballena tours create space for genuine connection with the ocean. Our guides know exactly where the turtles feed, which crevices hide octopuses, and how to help nervous beginners feel comfortable in the water. For anyone seeking an easy, rewarding introduction to snorkeling in Costa Rica, Marino Ballena offers the ideal combination of convenience, marine life diversity, and that rare feeling of floating above a protected reef just minutes from shore.
