Our Marine Conservation Expedition consists of 6 days of full adventure, learning, laughter, and purposeful work. This expedition on Costa Rica’s Pacific Coast is led by Marine Biologists Dr. Randall Arauz and/or Daniel Arauz.

This program focuses on monitoring the health of sea turtle populations in the area, which is crucial for the management and conservation of our local marine habitats.

• The expedition runs with a minimum of 6 participants required for confirmation.

• Dive sites are chosen based on daily weather and sea conditions

We’ll meet at the shop for the first of our two-tank local dive days. After a detailed boat briefing from our team, we’ll take a short 10–15 minute ride to our first dive site. This initial dive will serve as a check dive, giving everyone the chance to fine-tune weighting, get comfortable with their equipment, and adapt to local ocean conditions.

Following a 45-minute to 1-hour surface interval, we’ll head out for the second dive, where we’ll begin actively looking for sea turtles and start collecting data. We expect to return to the beach between 12:00 and 12:30 PM.

On Day 2, you will head out for a second 2-tank field research dive alongside the marine biologists. Building on the first day’s experience, you will actively assist with species spotting and support ongoing conservation efforts both underwater and on the boat when needed.

On Day 3, we will offer the option to upgrade your 2-tank dive to a 2-tank Catalinas Islands if the weather allows it (upgrade can be paid on-site).

On Day 4, you will head out for another 2-tank field research dive while exploring different local dive sites selected based on conditions and research priorities.

You will have the opportunity to take part in a special evening visit to a sea turtle sanctuary and nesting beach in the North Pacific of Costa Rica.

On Day 5, you will head out for another 2-tank field research dive while exploring different local dive sites selected based on conditions and research priorities.

Day 5 marks the final day of the expedition. Guests will complete their last 2-tank field research dives, putting into practice everything they have learned throughout the week.

In the afternoon, the group will gather for a closing debrief to review the week’s findings.
