The Isle of Erraid, Scotland
The tiny Inner Hebridean Isle of Erraid is a tidal island, just off the tip of the Ross of Mull.
For an hour or two either side of low tide, the Isle of Erraid is linked to the mainland by a broad expanse of sand that you can cross.
Erraid is one of the driest and sunniest places in Scotland, with less than 1,000 millimetres of rain and 1,350 hours of sunshine annually, so you’re virtually guaranteed great days out on the beach.
Brownsea island, Dorset
After glimpsing Brownsea Island, Enid Blyton wrote about Whispering Island in the Famous Five book, Five Have a Mystery to Solve.
Nowadays, the island is owned by the National Trust and said to be a wildlife haven, home to red squirrels, a variety of exotic birds, bats, and deer.
Accessible from Poole Harbour, passengers will need to board a small foot ferry to reach Brownsea which takes around 20 minutes and costs £13, and holidaymakers will also need to pay an admission fee to visit the island which is £.950 for adults and £4.75 for kids (although it's free for National Trust holders).
Anglesey, Wales
With over 125 miles of unspoilt coastline, in Anglesey you’ll find rugged cliffs, uncrowded sandy beaches and clear water.
The calm and shallow waters are ideal for a gentle swim, or for little ones to enjoy a paddle.
The whole island has been designated as an Area of Outstanding Natural Beauty so you can also explore the lush countryside.
Unst, Scotland
Unst is roughly 178 miles away from the Scottish mainland.
There are thought to be just 600 people living on the tiny island, making it the most northerly inhabited place in the UK.
Unst has just one pub, one hotel, one school, three shops and a lone bus route.
