Main image

Dall Island is a large, forested island in the Alaska Panhandle, part of southeastern Alaska’s island archipelago and named after the naturalist William Healey Dall.

The island is visited for its remote coastline, wildlife viewing and fishing opportunities rather than for developed tourist infrastructure; its rugged shores and nearshore waters are important habitat for marine species. Access is generally by private boat or local water transport and the island has little in the way of permanent visitor facilities.

Indigenous use and maritime activity have long been part of the island’s history; later mapping and naming by American naturalists and explorers gave it the current name.

Dall Island lies off the southwestern side of the Alexander Archipelago in the Alaska Panhandle and is separated from larger nearby islands by coastal waterways.

  • Name and character: Named for the naturalist William Healey Dall, the island is largely remote and sparsely populated with extensive shoreline used by marine wildlife.

How to Get to Dall Island #

Dall Island is remote and has no road connections; it is reached only by boat or floatplane. Access is typically by private boat or chartered floatplane from nearby coastal towns in Southeast Alaska or from ports in British Columbia (arrange a charter from the nearest regional service center).

Tips for Visiting Dall Island #

  • Treat Dall Island as a remote, no‑services destination: arrange a charter boat or floatplane in advance and expect to be self‑sufficient (fuel, food, communications) for the duration of your visit.
  • There are no formal visitor facilities-landings, trails and camps are informal-so research landing spots and local regulations before you go and file trip plans with Alaska authorities.
