You will participate in our marine conservation identification dives to discover the wonders of the marine world. We also cover many more topics from ocean acidification, climate change, to global warming and you will discover things you can do to combat these issues. Join us and make a difference!

ReefCI is located on a beautiful picture-perfect private island that is part of the Sapodilla Cayes Marine Reserve Park, located in southern Belize. Our island is a coral island located directly on the Belize Barrier Reef 25 miles from the mainland off the coast of Placencia, Belize. The island is about 1½ acres with lots of hammock space shaded by coconut trees. It really is a perfect Caribbean paradise surrounded by turquoise coral seas with dive sites 5-10 minutes away!
Accommodations are basic but clean and comfortable and can best be described as hostel-like. If you are expecting or wishing for a 5-star resort then our island is not for you. The location however is 5 star!! Quirky, stone cabanas surround the island and house our single volunteers.
Our main cabana building houses couples, families, and groups. Every cabana has incredible views of the Caribbean Sea! Imagine waking up to the sound of waves lapping against the shore and a spectacular Belizean sunrise! For groups, friends and couples, there are double, twin, family rooms in the main cabana building with their own bathroom. Volunteers staying in individual cabanas have shared bathrooms. We do not have air conditioning on the island as the strong trade winds provide a continuous cooling breeze on the island. However, rooms can occasionally become stuffy so all rooms have fans if needed.
There are no mosquitoes or sand flies on our island! We are blessed due to our location 25 miles from the mainland, the strong trade winds, and the absence of fresh water and suitable breeding habitat on the island. Our island is the perfect Caribbean castaway island!
Travel Details and Schedule
Our Marine Science Internship dive trips are Monday thru Friday – we depart for our island at 9:30am on Monday from Placencia, Belize and return to the mainland (Placencia) on Friday anywhere from 11am-1pm.

PADI Specialty Course – Invasive Lionfish
Thirty years after their accidental introduction, lionfish have conquered the Atlantic and Caribbean Oceans and are wreaking havoc on coral reef ecosystems. Unlike in its native Pacific Ocean habitats, there are no natural predators in the Atlantic and Caribbean to keep this invasive species in check. Hence, lionfish populations have exploded, gobbling up native coral reef fish that have no natural defense mechanisms against this invasive species. Lionfish threaten the very survival and sustainability of coral reef ecosystems in the Caribbean and Atlantic Oceans. Learn what action is needed to control the lionfish population and, learn practical ways to safely and humanely capture and euthanize these fish.
Prerequisite: PADI Open Water Certified and be at least 15 years old.
PADI Specialty Course – Coral Reef Conservation
Everyone likes to scuba dive or snorkel in warm, clear water on a vibrant coral reef, yet many people know little about what they’re seeing or the importance of reef ecosystems.

The Coral Reef Conservation specialty course will cover the following topics:
How coral reefs function and the complex nature of life on a reef.

Specialized deep diving equipment
Deep dive planning, buddy contact procedures and buoyancy control
Managing your gas supply, dealing with gas narcosis and safety considerations
