Sao Miguel, the largest island in the Azores, offers some of the most engaging snorkeling experiences in Europe. Thanks to its clear waters, volcanic formations, and abundant marine life, it’s a perfect destination for underwater exploration. We’re especially fond of the Glass Bottom Boat Tour & Snorkeling in São Miguel, which combines comfort with a chance to see the island’s underwater wonders without even getting wet — though there are plenty of options for those eager to jump in.

For those wanting an active day that combines hiking and snorkeling, the Sao Miguel: Hike and Snorkeling into the wild with a local is well worth considering.
