What Travellers Say
Reviews Summary
Visitors consistently rave about Caño Island, calling it a 'magical trip of a lifetime' and a 'super excursion.' The abundant marine life, including manta rays, sharks, and dolphins, is a major highlight. While some note occasional visibility issues, the overall experience is overwhelmingly positive, with many recommending specific tour operators for small-group, impactful adventures.
"There's no place like Cano! This is the magical trip of a lifetime. The best place to stay in the area is The Jaguar's Jungle Lodge. From there you can literally SEE the island from your room! Their trips are great because they are small groups of people as opposed to the groups of 15+ people all the other boats had. Highly recommended."
Leo Ramsey
"Super excursion snorkeling at Cano island. We tried 3 different spots and we saw a ton! We could even hear the whales.
On the way to the island and back we saw whales breaching and also some dolphins. On the way back the dolphins were racing with our boat and jumping around. They were so close we could almost touch them. It was a very unique experience! Our tour company was Bahia aventuras, I would definitely recommend them!"
Julien Riegel
"I recently went scuba diving at Caño Island and had a great time. Only gave 4 stars because visibility was lacking a bit but we saw lots of cool wildlife, colorful coral, etc, and I really enjoyed my time!"
