Tongass National Forest

The Tongass National Forest covers 17 million acres and includes islands, mountains, glaciers, ice fields, fjords, waterfalls, and an abundance of wildlife. Included in the forest is Prince of Wales Island, one of the largest islands in the USA. On the island is El Capitan cave, with a network of passages. Tours of the cave are offered by the Forest Service during the summer months.

The Forest Service also provides rental cabins, most of which are accessible only by air.
