Snakes in Alaska: Identification Guide and Where to Start Looking
Snakes do show up in Alaska, and the best first step is matching habitat, timing, and recent local conditions. Start with the state wildlife hub, compare likely cover and movement windows, use the animal facts page for field marks, and plan one realistic route before heading out.

What snakes have been found in Alaska?
The only snake species ever documented in Alaska is the common garter snake (Thamnophis sirtalis), and that is extremely rare. Most reports come from the southeast region, particularly near Ketchikan or Juneau, likely from hitching rides on barges or in cargo. These snakes are small, non-venomous, and typically 18-26 inches long. They have three distinct stripes: one down the back and one on each side. There is no established breeding population.

How can you identify a garter snake in Alaska?
If you spot a snake in Alaska, check for a slender body with three light stripes (yellow, green, or white) on a darker background. The head is slightly wider than the neck, but not triangular like a pit viper. Eyes are round. They are not aggressive and will try to escape. Garter snakes are the only snake likely to be seen, but again, sightings are extremely rare. For more detailed identification, see oursnake identification page.
What animals are most often mistaken for snakes in Alaska?
By far, the most common 'snake' sighting in Alaska is actually a stick, a root, or a piece of rope. Also, eels (like the Pacific lamprey) and certain fish can wriggle and look snake-like from a distance. The short-tailed weasel (ermine) in summer coat might also be mistaken. If you see something slithering, it's almost certainly not a snake. Focus on the key identifier: a true snake has scales, no legs, and a forked tongue.

Where in Alaska have snakes been spotted?
The few credible snake sightings in Alaska come from the southeast panhandle, especially around Ketchikan, Juneau, and Skagway. These are often near ports or ferry terminals. There are also isolated reports from Anchorage and Fairbanks, but those are almost certainly escaped pets. If you're looking for snakes in Alaska, the best odds are in the warmer, wetter coastal areas in summer, but expect to find only garter snakes if anything.

What is the best time of year to see a snake in Alaska?
Snakes are cold-blooded and need warmth. The best time is the warmest months: June through August. Even then, daytime temperatures rarely reach high enough for snakes to be active for long. If you are in southeast Alaska on a sunny day with temps above 70°F, you might encounter a garter snake basking on a rock or log. Most people who spend time in Alaska never see a snake, so don't set your hopes high. Alaska's climate is tough on reptiles; learn more on ourAlaska wildlife page.
How do you distinguish a snake from a lookalike?
Look for these clues: Snakes have scales that are smooth and dry, no visible legs or ears, and a long slender body. They move side to side. A snake will flick its forked tongue. In contrast, a stick is rigid and doesn't move; a fish or eel has fins and gills; a weasel has fur and legs. If you're not sure, watch from a safe distance.
