With its diverse landscape of volcanoes to beaches, Costa Rica is celebrated as one of the Earth’s most biodiverse locations. The heart of this biodiversity lies in the Osa Peninsula and surrounding areas. Located in the southern part of the country and extending into the Pacific Ocean, the Osa Peninsula is bordered by the Golfo Dulce (“Sweet Water”) to the east and the Pacific Ocean to the west.

The first part of our Costa Rica science students tour takes place in the San Jose area. Students will be introduced to Costa Rica’s cloud forests and animals at the La Paz Waterfall Garden and Poas Volcano. On the same day, a fun and educational visit to a coffee plantation (one of Costa Ricas’ major industries) will help students understand coffee production from the bean to the cup.

The real adventure begins on this Costa Rica science students tour when we hop on a prop plane and fly 45 minutes down to the Osa Peninsula to Puerto Jimenez. From here, we take a boat across the Gulfo Dulce to the edge of the Piedras Blancas National Park. We spend 2 nights here. Daily adventures will take us by foot, paddle, and snorkel to see and learn about animals and plants of primary rainforest, mangroves, and the Gulfo Dulce.

To reach our next destination on the Costa Rica science students tour, we take a boat back across the Gulfo Dulce to Puerto Jimenez, then take 4 x 4 taxis two hours to the end of a dirt road. To access our next eco-lodge, we need to walk 2 miles through the rainforest! At this location, we will hike on the trails near the Corcovado National Park. We’ll even climb onto platforms in a 130 ft tall Garlic Tree using ropes and harness to learn about ecology in the treetops.

The morning before the students depart from our Costa Rica science students tour, we explore the town of Sarchi, learn about it’s history, and participate in an art project.

Costa Rica science students tour is an active adventure. Students will be hiking up to 2 miles 1-2 times per day, depending on the activities. Most activities are easy to moderate for healthy teens. Students who are not very active should consider a walking program before the trip to get prepared for their adventure. It will be hot, and you will get sweaty. Anyone can do this trip, but the more prepared the students are, the more enjoyable the experience will be on our Costa Rica science students tour and adventure.
