Discover an underwater world with a glass bottom safari

Join the islands’ only glass-bottom boat for a unique journey beneath the surface, where large viewing panels reveal a hidden underwater world as you travel. Designed for comfort and visibility, the purpose-built boat carries small groups, offering uninterrupted views of marine life gliding through the clear waters below.

As you explore the shores and surrounding islets, keep watch for Atlantic grey seals, seabirds, and even dolphins, while beneath the surface you’ll spot fish, kelp forests, and drifting jellyfish. Each trip showcases the rich biodiversity of the Isles of Scilly, one of the UK’s most vibrant marine environments.

With a range of routes and durations to choose from, every trip is guided by an experienced local skipper with deep knowledge of the islands’ wildlife and history. Whether you’re seeking a short family-friendly adventure or a longer wildlife safari, it’s a relaxed and memorable way to experience the Isles of Scilly
