Southeast Alaska is completely different from the rest of the state.

This is coastal Alaska—rainforest, ocean, islands, and towns that are not connected by road. Travel here happens by boat or plane, and the entire region feels more like a chain of remote coastal communities than a connected landmass.

If your trip involves a cruise, ferry, or coastal exploration, this is where you’ll likely spend your time. You can start mapping out transportation and logistics in the Alaska Travel Planning Guide, then build your route from there.

Geography & Landscape

Southeast Alaska is defined by water and forest.

The region sits along the Inside Passage, a network of islands, channels, and fjords protected from the open ocean. Dense temperate rainforest covers the land, and mountains rise steeply from the coastline.

Glaciers, waterfalls, and coastal cliffs are common here, and the environment feels lush compared to the rest of Alaska.

Climate & Seasons

Southeast Alaska has a maritime rainforest climate.

Summers are mild, usually in the 50s to 60s, but rain is frequent. You should expect wet conditions at any time of year.

Winters are relatively mild compared to the rest of Alaska, often staying above freezing, but still very wet and cloudy.

Alaska Native Culture

Southeast Alaska is home to the Tlingit, Haida, and Tsimshian peoples.

These cultures are deeply connected to the ocean and forest, with traditions centered around fishing, carving, and coastal living. You’ll see their influence throughout the region in totem poles, artwork, and community life.

This is one of the strongest regions in Alaska for visible cultural presence and history.
