This aquatic adventure will give you the rare opportunity to witness the splendid beauty and bio-diversity on and around the Marietas Islands, a cluster of rocky isles located at the border of the Pacific Ocean in Banderas Bay. Join our naturalist English-speaking guides cruise across the beautiful waters of the Bay. Along the way, we’ll be on the lookout for marine mammals that inhabit this enormous body of water.

I have been to the Bahamas many times, but Marietas Eco Discovery is one of my favorite trips! It includes everything that everyone should do here. As a Bahamas veteran, I can say only the best about this experience!

Thanks to the professional guides! I was a bit worried about kayaking because I had never done it before, but the instructions were great and I had such a good time!
