The courses range from Open Water Diver through to Advanced Adventurer, and specialties such as Buoyancy, Marine Ecology and Fish Identification are also available for volunteers who have completed the Open Water and Advanced certification courses.

Marine Conservation Volunteering in Belize

Marine Conservation Volunteer - Diving in Belize with IVHQ

Want to take part in a marine conservation on an island in the Caribbean? Marine Conservation volunteering in Belize gives you the unique opportunity to live on, and dive in the ocean around, a beautiful and remote island in the Caribbean sea. This small island sits 26 miles off the mainland of Placencia, Belize.

During your weekends, head back to mainland Belize to get your dose of life above the waves - start the day with an amazing coffee, then explore ancient Mayan ruins, wander through one of the many wildlife sanctuaries and finish the weekend off zip-lining through the jungle.

You’ll become a pro at spotting and identifying marine wildlife, including lionfish, corals, whale sharks and queen conch! On a day-to-day basis, you’ll work alongside local marine biologists to gather data, conduct surveys and remove invasive species.

Your role on this project can include:

  • Coral Reef Surveying: Climate change is having a tangible effect on coral reefs, and volunteers play an important role in collecting data about these changes, which is shared with conservation groups.
  • Invasive Species Removal: Lionfish are native to the Indo-Pacific and were introduced to the Caribbean by humans. They have no natural predators, feed on the native species and reproduce at a fast rate. You’ll help to remove these invasive and damaging species by spearfishing and taking the fish back to the island where they can be eaten or have their spines turned into jewelry.
  • Marine Species Survey: Lobster surveys are conducted regularly to gain insights into why their population has decreased significantly over the last few decades. Queen Conch is a large marine mollusk and is overfished due to the commercial value of its large spiral shell. The purpose of carrying our Queen Conch surveys is to gather data on their breeding patterns.
  • Whale Shark Research: The whale shark is the largest fish in the sea and survives mostly off plankton. Their fins and meat are well sought after, which has led to overfishing and their population declining. While it can’t be guaranteed that you will see a whale shark during your time on the program, if you do, it will certainly be an amazing experience!

Certified divers will be able to start diving and assisting with marine conservation volunteering in earnest on arrival to the island. For volunteers completing their certifications on the island, the first three days consist of completing the written and practical certification modules. Once certified, you will join the conservation efforts alongside the other volunteers.

Those who have already completed their PADI Open Water Certification have the option of taking more advanced courses, such as Dive Master Certification, Rescue Diver, and much more.

It’s important to note that due to the size of the island, there is a maximum capacity of 17 volunteers on the program at any given time. With this in mind, we recommend applying and registering with as much notice as possible, to maximise your chances of securing a spot on this unique marine conservation program.

Belize Volunteer Program Highlights:

  • The program is based on a beautiful and remote island in the Caribbean sea
  • Flexible program durations from 1 - 8 weeks
  • The program is available year-round and starts every Monday
  • Affordable program fees from US$855 for one week
