About Abe's Snorkeling & Biobay Tours
Abe's Snorkeling & Biobay Tours is the longest-running tour company on Vieques Island, with over 30 years of experience guiding visitors through the island's most spectacular natural attractions. Based in the seaside town of Esperanza, Abe and his crew have introduced thousands of travellers to Mosquito Bay — the brightest bioluminescent bay in the world — as well as the pristine snorkelling reefs that ring the island.
Their most popular offering is the Mosquito Bay Bio Bay Night Tour, a kayak-based outing where guests paddle through waters glowing with billions of dinoflagellates. During the day, they run snorkelling excursions to the reefs and seagrass beds around Vieques, where encounters with sea turtles, rays, and nurse sharks are common. They also offer mangrove kayaking tours and combination packages that bundle multiple activities into a single day on the water.
Abe's reputation is built on three decades of consistent, safe, and genuinely fun tours led by guides who grew up on Vieques. Their deep local knowledge — of tides, weather patterns, and the best seasonal spots — is impossible to replicate. Visitors consistently praise the personal attention and authentic island experience that only a veteran Vieques operator can deliver.
