10 of the best island adventures around Britain

From Anglesey to Jersey, escape from everyday life and find dramatic landscapes with a trip over the water from a new book on island bagging

Enjoy the last of the season’s warmer waters with a swim from the golden sands of Kynance Cove around the jumble of translucent green serpentine rocks at the base of this island. Start this wild 2km swim from the sandy tombolo between the mainland and island at the west end of Kynance Cove (note at high tide the beach and tombolo disappear, so check tide times for Lizard Point). Swim independently or guided by Sea Swim Cornwall (some experience of open-water swimming necessary, £40 a trip). Finish with a coffee and pasty in the Kynance Cove Beach Cafe nearby.
