        Most of my earliest childhood memories are of the beach-in the hot sun, building sandcastles,

burying Dad in the sandNow the coast has a pleasant and relaxing attraction beyond words. I looked

forward to a windy cliff-top walk or a rainy day rock-picking just as much as those rare moments when

Iget to a short sleep in the sun. But there's nothing more pleasurable than turning up at a beach to find it

deserted.

      These are my favourite secret beaches-ones either not well known or take a bit of effort to get to.

Most of those listed scored highly in the Marine Conservation Society Good Beach Guide 2009; the

others are too secret even for them.

     Sennen Clove is just a mile northeast of Land's End, the westernmost point of mainland England. It's

a beautiful spot, with white sands, deep green sea and amazing sunsets over the Isles(群岛) of Scilly, 28

miles away.

     The west-facing beach is popular with surfers, with bigger waves and winds often found at the Gwenver end. There's a beach restaurant with good views of the bay and the sunsets.

     The smallest of Isles of Scilly, Bryher is a mile long, half a mile wide-and a natural wilderness of

unbelievable scenery. Walk along the narrow sandy roads to the eastern seaboard and you come to

two quiet beaches.

     Green Bay has views over to the palm trees of Tresco's Abbey Gardens, and a little further south is

Rushy Bay, a beautiful beach facing the deserted island of Samson.

     On Bryher, farm shops sell locally grown produce, and they trust you to leave the money in the pot.

It's that kind of place.
