If you’re heading to Vieques, Puerto Rico, and craving a truly unique experience, then this Clear Bottom Kayaking and Snorkel Reef Exploration tour might just be what you’re looking for. For around $145 per person, you get about two hours of paddling and snorkeling that reveal some of the most vibrant marine life and natural phenomena in the Caribbean. Starting from the lively Esperanza Beach area, the tour takes you out to Cayo Real, a calm islet just off the coast, with a focus on eco-friendly adventure and intimate encounters with nature.
What we love about this experience is the personalized small-group setting, limited to just 8 travelers, which means fewer crowds and more personalized attention from your guides. The ability to see beneath the water through clear-bottom kayaks offers a fascinating perspective that enhances the thrill for both snorkelers and casual observers alike. Plus, the chance to explore Puerto Mosquito Bay, the world’s brightest bioluminescent bay, adds a magical glow to your night adventure.
The only caveat? This tour’s reliance on good weather could be a consideration—if storms roll in or conditions turn rough, your plans might shift, though a full refund or rescheduling is available.

A Closer Look at What You Can Expect

This tour begins at 107 Calle Flamboyan in Vieques, a convenient meeting point near public transportation. From there, you’re introduced to your guides, who are experts in both marine biology and local history. The initial part of the tour involves paddling out in a clear-bottom kayak, giving you a stunning view of the underwater world without even getting wet—perfect for those wary of snorkeling or just wanting to see more of the marine ecosystem.
Paddling out to Cayo de Afuera, a tranquil island shaped like a whale, is an enjoyable part of the trip. You’ll love the way the crystal-clear waters allow you to observe a vibrant variety of fish, lobsters, octopuses, and even the occasional stingray—just as Thomas from a recent review described, “a huge stingray, octopus, lobster, and a variety of fish and life chillin’.” This firsthand glimpse into reef life enhances the overall experience and adds a sense of discovery.
Once at the islet, you’ll have the opportunity to snorkel with provided equipment, exploring the reef’s colorful inhabitants up close. The guides explain the science behind the glowing waters of Puerto Mosquito Bay, which, as they detail, is the brightest bioluminescent bay in the world. While the tour focuses primarily on Cayo Real and its surrounding waters, many find this segment especially magical when viewed under a night sky—think stars twinkling above, and the water shimmering with every movement.
We appreciated the environmentally conscious approach of Mosquito Bio Bay Tours, which emphasizes preserving the natural beauty of Vieques’ marine ecosystems. The tour’s small size, respectful conduct, and focus on eco-tourism make it a responsible choice for travelers concerned about sustainability.
