How to get there
Plan your arrival at Tamandua Biological Station: the final road, transport connections and changing rainforest conditions.
Location and access
Tamandua Biological Station is situated approximately 5 km from Agujitas Beach in Drake Bay. Access to Drake Bay is available via bridges, but the road from Drake Bay to the station presents significant challenges, including steep slopes and six river crossings.
To enter by car, a high-clearance 4x4 vehicle is mandatory. During rainy conditions, river levels can rise and certain sections of the road become extremely slippery and difficult to navigate.
Transportation options
If you are using public transportation, you can travel toward Sierpe using TRACOPA services from San José. The current information available to Tamandua includes an 8:30 am service. Another option is to travel via Palmar Norte and continue to Sierpe by bus or taxi. Allow around four to seven hours for the bus journey, including two stops. Please confirm current bus and boat schedules, routes, connections and journey times with Tamandua before travelling, as services can change.
Once in Sierpe, there are two public boats to Drake Bay daily, leaving at 11:30 am and 4:00 pm (16:00). Reserve your boat seat in advance, confirm the schedule and arrive in time to manage your luggage before departure. We can help you with the boat reservation. The boat ride to Drake Bay takes around 40 minutes and passes through the Térraba–Sierpe wetland, with its mangrove forests and the possibility of observing crocodiles.
You can also fly with Sansa from the domestic terminal of Juan Santamaría International Airport to Bahía Drake Airport. The flight takes approximately 40 minutes; confirm the current itinerary when booking. Once you arrive, you will need a taxi to reach the station. We can assist you with arranging this transfer.
If you are coming with a rental car, check the weather and access conditions in Bahía Drake beforehand. You can travel through Chacarita or cross the Sierpe River by ferry. In heavy rain, leaving the car in a parking lot in Sierpe and continuing by boat may be the safer option. Discuss current conditions with Tamandua before choosing a route. Once in Drake Bay, we can assist in organising internal transfers with local taxis.
Climate considerations
The rainy season generally runs from July to November, with drier conditions from December to June. Conditions vary from year to year, and rain can fall in any month. Come prepared for rain and check access conditions before travelling: rising river levels can sometimes make vehicle crossings impossible.
