ITINERARY
DAY 1: ARRIVE TO SAN JOSE
You will be picked up at the San Jose Airport and taken to La Rosa de America in Alajuela, a quiet hotel with beautiful gardens and a pool. Get a good night's sleep to rest up for the fast paced trip. (Dinner not included this first night and can be purchased at the hotel for $10).
DAY 2: DRIVE TO THE OSA PENINSULA
After breakfast, you'll head to the South Pacific coast in a private vehicle (about a 5 hour drive). Along the way, you will stop for lunch and take in the beautiful views. After settling in to your cabins, researchers from our partner Latin American Sea Turtles (LAST) will give an orientation to the turtle research and train you in data collection techniques.
This evening, relax and get a good night’s sleep. Overnight at Delfines de Golfo, a simple family lodge with electricity, private bath with hot water, and tv’s.
DAY 3: SEA TURTLE RESEARCH
Today is all about sea turtles. Head out in a shaded boat with researchers to help set nets in key turtle spots (timing dependent on the tide). Once caught, researchers will bring them to the beach where you will have the opportunity to help carry in the turtles and help measure, weigh, and release them.
You’ll be looking for green turtles and hawksbill turtles. In between turtles, take a swim in the beautiful Golfo Dulce or explore the coastline to look for wildlife like scarlet macaws and sloths.
DAY 4: MANGROVE RESTORATION
Today, you will be protecting sea turtles by land, by supporting reforestation and organic farming. This morning, you will participate in LAST's mangrove reforestation program by working in the nursery and planting young trees. Mangroves are critical habitat for juvenile sea turtles, fish, and other ocean life and this area has lost much of its mangrove forests over the past few decades (the wood is popular for construction).
In the afternoon, there will be free time to take a swim, rent a sit-on-top kayak to paddle around on the gulf, visit Puerto Jimenez to souvenir shop, or other options. That evening, the group will gather at the cabins for dinner. (B, L, D)
DAY 5: HAWKSBILL TURTLE RESEARCH
Today you will be studying hawksbill sea turtles, which are critically endangered around the world primarily due to the trade in products made from their shells. These turtles are also usually juveniles and are smaller than the greens, averaging 2-3 feet in length and 30-40 lbs.
You will collect data including their length and width, check their shells for parasites (not a risk for humans), and weigh and tag them before releasing back to the water. (B, L, D)
DAY 6: ORGANIC FARM CHOCOLATE TOUR
Today you'll visit a nearby organic farm to taste a variety of fruits from around the world and to learn about the origins of chocolate, which is native to this region. You will see the entire process of making chocolate, from growing cacao to harvesting, drying, fermenting and of course tasting, finishing up with a dark chocolate fondue.
The afternoon is open to choose from a number of options. Dinner will be with the group at the cabins. (B, L, D)
DAY 7: RETURN TO THE CENTRAL VALLEY
Today, after breakfast, the group will pack up the bus and head back north to San Jose. The drive will be broken up with lunch and a walk along the way, getting back to the city in the afternoon. Feel free to take a walk in the city and visit a museum if time allows, before joining the group for a celebratory dinner on the town this evening. Overnight at Rosa del Paseo. (B, L, D)
DAY 8: DEPART FOR HOME
Rosa del Paseo provides a delicious breakfast for your last morning. After, head out for the airport in time for your flight, taking along your memories, photos, souvenirs, and stories to tell friends! You can also extend your stay and visit other parts of the country. (B)

Is This Trip Right For Me?
Costa Rica is a safe and beautiful country that receives more than 1 million international tourists annually. This is a fairly an active trip that requires some of physical fitness and an ability to manage sometimes challenging conditions including weather and heat, bugs, and long bus rides.
