Describe the island in the novel Kidnapped.

From the text:

The second day I crossed the island to all sides. There was no one part of it better than another; it was all desolate and rocky; nothing living on it but game birds which I lacked the means to kill, and the gulls which haunted the outlying rocks in a prodigious number. But the creek, or strait, that cut off the isle from the main-land of the Ross, opened out on the north into a bay, and the bay again opened into the Sound of Iona; and it was the neighbourhood of this place that I chose to be my home; though if I had thought upon the very name of home in such a spot, I must have burst out weeping.
