Snakes in Washington: Identification Guide and Where to Start Looking

What Types of Snakes Are Found in Washington?

Washington hosts about 15 snake species. The most widespread are the common garter snake, western terrestrial garter snake, and the gopher snake. You'll also find the northwestern garter snake, rubber boa, and the northern Pacific rattlesnake in the eastern parts. For a full species breakdown, check out oursnake hub.

How Can You Identify the Most Common Snakes in Washington?

Focus on pattern and scale features. Garter snakes have three light stripes running the length of their body. Gopher snakes have a blotched pattern similar to a rattlesnake but lack a rattle and have a narrow head. The northern Pacific rattlesnake has a broad triangular head, vertical pupils, and a rattle at the tail. Start with stripe vs. blotch to narrow it down.

Where in Washington Do You Usually See Snakes First?

Your best chance is east of the Cascades in dry, open habitats: sagebrush flats, rocky slopes, and near agricultural fields. West-side snakes are more common in forest clearings, meadows, and along stream banks. Start with the Columbia Basin and the lower elevations of the Okanogan region.

When Is the Best Season for Snake Sightings in Washington?

Snakes emerge in early spring (April) and remain active through October. Peak activity is on warm days between 70°F and 85°F, especially after a rain. Early morning and late afternoon in late spring and early summer give you the best odds.

Are There Venomous Snakes in Washington?

The only venomous snake is the northern Pacific rattlesnake. It's found east of the Cascades, especially in dry, rocky areas. It has a heavy body, distinct rattle, and a diamond-shaped head. Non-venomous lookalikes like gopher snakes often mimic its pattern but lack the rattle and have a narrower head. Learn more about safe identification on oursnake page.

How Do You Tell a Gopher Snake from a Rattlesnake?

Gopher snakes are often mistaken for rattlesnakes because they flatten their heads and hiss. Key differences: rattlesnakes have a thick body, a rattle, vertical pupils, and a heat-sensing pit between eye and nostril. Gopher snakes have round pupils, no rattle, and a narrower head. If you see a snake with blotches but no rattle, it's almost certainly a gopher snake.
