Audio Guide of Sierpe River

Sierpe River is a natural river, so it does not have opening and closing hours. The main access is through boat tours from Sierpe, which is the departure point for Drake Bay and the Osa Peninsula. Most lodges and tour operators in Drake Bay offer excursions along the river. We recommend contacting local operators such as Ojochal de Sierpe or Sierpe and Drake Bay Tours to arrange your trip. Departure times are usually in the morning.

Navigating the Sierpe River itself does not have a fee, as it is a public waterway. However, boat tours that explore its mangroves and connect to Drake Bay, or those specifically for wildlife watching, do have a cost. Prices vary depending on the duration, the type of boat, and whether specialized guides are included. We suggest asking tour operators directly about their rates.

The length of the visit can vary depending on your interests. A standard mangrove and wildlife observation tour can last between 2 and 4 hours. If you are using the river as transport to Drake Bay, the boat trip from Sierpe can take approximately 1.5 to 2 hours, not including stops for wildlife sightings. For a more complete experience, consider a half-day tour that includes exploring the tributaries.

The Sierpe River is vital because of its mangrove system, one of the largest and most important in Central America, recognized for its rich biodiversity. Historically, it was a key transport route for Indigenous communities and later for the banana industry. Culturally, its mangroves are a crucial ecosystem that supports local fishing and provides irreplaceable habitat for countless species, a true natural treasure of Costa Rica.

The best time to visit is during the dry season (December to April), when the weather is more stable and there is less rain. However, the rainy season (May to November) offers a lusher landscape and fewer tourists. As for the time of day, the early morning hours (between 6 and 9 AM) or late afternoon (between 3 and 5 PM) are ideal for wildlife watching, as animals are more active.

Accessibility for people with reduced mobility can be challenging. The boats that are usually used often require stepping up and down small steps. We strongly recommend checking with tour operators in advance to see whether they offer wheelchair options or adaptations, or if they have assistance staff. Some boats may be easier to board than others, so prior communication is key.

So many! The Sierpe River is the gateway to the stunning Drake Bay and Corcovado National Park, known for its incredible biodiversity. You can also visit Caño Island National Park for diving or snorkeling among coral formations. Other activities include birdwatching, jungle hikes, and dolphin- and whale-watching tours (in season).

Of course—here are a few: bring insect repellent (essential), sunscreen, a hat, sunglasses, and a camera with good zoom. Wear light clothing in neutral colors. Don’t forget your binoculars for better wildlife viewing. Listen to your guide—they know the best areas for sightings. And above all, maintain a respectful attitude toward the natural environment—it is a very fragile ecosystem!
