The interior of the island is a tableland, of which the highest point, 375 feet 

 above the sea, is at the Mill. The cliffs rise in general to about 200 feet, 

 but on the north and south, and also on the west of Brecqhou, there are 

 slopes down to the sea. The base of the cliffs is seldom accessible, and 

 except in a few of the bays no beach of any kind exists.
