About Us

Osa Great Adventure is a family-owned business that has been organizing and running tours in Corcovado National park since 20208, it has been founded by Allan Guevara, who has been working as a tour guide in Corcovado before founding the tour operator. 

This has given us a huge advantage since we do know really well Corcovado and have deep knowledge of the field.

Why Choose Us

We are focused on responsiveness and try our best to organize tours for travelers that contact us. This is very important since Corcovado National Park has limited spaces.

Diane WNot to be missed: two-days at Sirena Station

We spent a total of 5 weeks in Costa Rica over the past year, spending nights at over a dozen locations—all of which were picked for their proximity to nature. Our two-day/one-night tour at Sirena Station was easily the most unique for us and definitely not to be missed. A one-day trip to Sirena definitely would not have given us enough time to explore this area. Osa Great Adventures provided timely communication and fulfilled all their promises—arranging guide services, transportation, park access, lodging, and meals.
