Uvita de Osa is a small town on the Pacific coast of southern Costa Rica, on the shore known as Bahía Ballena. It is the tourist and adventure tour hub of the Costa Ballena region, so travelers use it as a base for tours. Restaurants and places to stay are easy to find in town. Local operators run tours ranging from whale watching to horseback riding.
Humpback whales pass through regularly. Some spend the season off Alaska and California, while others come up from Antarctica, each group at a different time of year, so the season you visit shapes which whales you may see. Dolphins, sea turtles and other whales, such as false killer and pilot whales, also share these waters. Hacienda Baru National Wildlife Preserve lies about fifteen minutes north of Uvita, and more than 350 bird species have been recorded there, including scarlet macaws and many hummingbirds. Venomous snakes live in the area, so watch your step on trails.
Uvita in five
- Plan the whale tail around low tideSINAC's Spanish page says the tombolo can be entered only during the six hours of low tide, and Playa Arco only at low tide via the Ballena sector. Check the tide table at the entrance before you set a time.
- Carry a card for the park ticketSINAC's Spanish page lists $6.78 for non-resident adults, tax included, payable only by credit or debit card. The ticket is valid all day, and the English page says it covers the four sectors.
- Book whale watching for the right monthsSINAC gives two humpback seasons: December to April from the north and July to November from the south. Resident dolphins are seen all year. Pick a licensed operator and ask about its viewing distance.
- Snorkel at low tide, with mask onlySINAC's English page says snorkeling near the tombolo is allowed at low tide with a mask and snorkel, and that diving fins are not allowed. Ask rangers if the rule has changed before you buy gear.
- Arrive by coach and plan the last legSINAC says Tracopa coaches from San José via the Costanera stop in Uvita, and Transportes Blanco runs San Isidro to Uvita. From town you arrange private transport to the sector you want.Quepos

When can you walk out to the whale tail?
Only at low tide, for roughly six hours a day on SINAC's reckoning. Arrive early, check the tide table posted at the entrance and walk back before the water returns.
What is the best time for whale watching in Uvita?
SINAC gives two humpback seasons, December to April and July to November, with resident dolphins year round. December to April falls in the dry season and July to November in the green season, so the weather differs.
How much does Marino Ballena cost?
SINAC's Spanish page lists $6.78 for non-resident adults and $5.65 for children, tax included, payable by card only. Check the entrance booth for the current rate and whether the sector you choose is open.
How do you get to Uvita from San José?
By Tracopa coach on the Costanera route, which SINAC says stops in Uvita, or by road. From San Isidro, Transportes Blanco runs to Uvita. Arrange a taxi or private transport from town to the park sector.
Is Uvita good for a first Costa Rica trip?
Yes if you want a quieter Pacific stop with a marine park, but it is far from the main airports. Combine it with Quepos and Manuel Antonio to the north, and give the southern Osa its own trip.
