Brownsea Island

Dorset

Owned by the National Trust, Brownsea Island sits in Poole Harbour in Dorset. The boat trip to the island features a postcard-worthy coastline stretching 2.4km.

The island itself is a unique haven for wildlife and is home to a rich habitat including woodland, heathland and a magnificent lagoon. Although there is no accommodation on the island itself, visitors can stay nearby on the Poole mainland.

Isles of Scilly

The Isles of Scilly are an archipelago off the Cornish coast, in southwest England, just 28 miles off Land’s End. Famed for its temperate climate and flourishing sub-tropical gardens, Scilly consists of more than 100 islands, most of them rocky outcrops inhabited only by seals and seabirds.

The slow pace of life harks back to another age: there is very little traffic and the closest it gets to a rush hour is a crowd of day-trippers queuing on St Mary’s quay for the morning boats to the ‘off islands’ (St Martin’s, Tresco, St Agnes and Bryher).

Stay at the iconic Star Castle, a star-shaped fortress built in 1593 featuring thick stone walls, a dry moat, bell tower, dungeon bar and views of the off islands from lawned ramparts.

Sleep under oak beams in the castle or in an airy garden room, and dine in one of two atmospheric restaurants. The food is superb: home-grown produce, fresh seafood and, from this year, wines from the hotel’s own Scillonian vineyard. Doubles from £306, including a three-course dinner.

Anglesey

Wales

The Isle of Anglesey, or Ynys Mon, is an island and county in the northwest of Wales.

The island has a population of almost 70,000. With a high penetration of Welsh speakers, tourism is one of the major industries for the area.

Famous faces from Anglesey include Lemmy from Motorhead and actor/comedian Dawn French.

The island is rich with history; situated on the shore of the Menai Strait, Plas Newydd House & Gardens dates back to the 18th century. Now managed by the National Trust, it houses a military museum, an Australian arboretum and an exhibition of Rex Whistler paintings from the 1930s.

A must-visit for those wanting to have a staycation further afield amidst the beauty that is Wales.
