Fox Island Wilderness Lodge, Alaska
An hour's boat ride from the town of Seward on Alaska's Kenai Peninsula, Fox Island Wilderness Lodge has just eight cabin bedrooms, each presenting wonderful panoramas of sea and mountains. Wildlife on the tiny island is plentiful: bald eagles nest here, and on summer evenings sea lions play in the bay beyond the lodge.

Lupita Island Lodge, Tanzania
Fringed by dramatic rocks and beaches, and with a private airstrip, tiny Lupita lies on Lake Tanganyika. Last December a sublime lodge opened here, its 14 open-sided villas offering fabulous furnishings and views. Beyond the gardens is bush – home to otters and vast numbers of birds. Each villa has a plunge pool, and activities include kayaking and snorkelling.

Home to puffins, guillemots and seals, and with a resident human population of just 28, Lundy Island lies 16 miles off the Devon coast, in the Bristol Channel. Tibbets, a former signal station, was built in 1909. The accommodation for four is hardy: you sleep in bunks and pump your own water. It is the only property here with no electricity.
