For the full Scilly experience, hire a motor boat or sailing boat from Hut 62 directly on Green Bay and see the islands from a different perspective. Hire some fishing tackle and catch a few mackerel whilst you are at it!
You can also indulge in some watersports and get up close and personal with marine life on a SUP, pedalboard, kayak or even a transparent kayak for the best view of what lies beneath.
