The western shores of Bleaker Island are low-lying and fringed by shallow stone beaches.

The east coast of the island is characterised by low cliffs, interspersed with sand and pebble beaches and gulches and is directly exposed to the Atlantic Ocean.

The island was managed by Arthur Cobb, a locally well-known agriculturalist and amateur naturalist, in the early 20th century who wrote a book on the subject, containing forty six of his own black and white photographs.

The most famous of these was the French tall ship 'Cassard' wrecked on the southern tip of the Island carrying a cargo of coal in May 1906.

Overgrazing was a problem but reduced grazing pressure is helping the slow regeneration of tussac and native flowering plants.
