Marine & Environmental Conservation Internship in Costa Rica

The 4-week Marine and Environmental Conservation Cohort Internship in Costa Rica costs $4,980. The fee covers housing, in-country transfers, meals, medical insurance, organized excursions, and 24/7 support. Flights, visas, and personal expenses are not included, giving participants the flexibility to manage their own travel.

The internship runs for 4 weeks, from January 4 – 31, 2026. Participants rotate through multiple project sites, including wetlands, coastlines, and coral reefs. Each week is dedicated to a different conservation focus, such as sea turtle protection, reef restoration, or marine debris reduction, ensuring a well-rounded, hands-on experience.

Interns assist with sea turtle patrols, coral reef monitoring, bird counts, and community education programs. Additional activities include beach clean-ups, snorkeling, and guided tours of ecosystems like mangroves and rainforests. Group excursions, cultural events, and cohort-based activities complement conservation work, offering both learning and exploration.

The program is open to university students, graduates, and conservation enthusiasts with at least intermediate English. A background in biology or environmental studies is helpful but not required. No Spanish is necessary, though participants will have the chance to learn basic phrases through daily interactions and informal lessons.

Applications are open until September 14, 2025, for the Winter 2026 cohort. Interested participants can submit an online application through World Endeavors. Once accepted, interns receive pre-departure guidance and orientation materials to prepare for travel, conservation work, and living arrangements during the 4-week internship abroad.
