So who wants to go on a UK holiday where the sea is as good as (although maybe not as warm!) the Caribbean or South Africa?! Deserted beaches and turquoise waters surround this small island filled with subtropical plants and pretty rock gardens. The Scilly Isles is 28 miles off the coast of Cornwall and offers the most exceptional staycation summer escape, it’s a hidden secret and once you have experienced it you will want to go back every year!
