Ahjumawi Lava Springs State Park

Ahjumawi Lava Springs State Park is a remote California state park that protects a complex of spring-fed waterways and low basalt lava flows in the northeastern part of the state. It preserves a largely undisturbed wetland and freshwater spring system important for regional wildlife.

Canoeing and kayaking through clear, spring-fed channels is the principal visitor activity; trails and road access are minimal. Shoreline camping is available in a limited number of primitive sites and the park is used for wildlife viewing and boating rather than traditional day-use facilities.

The landscape was formed by volcanic lava flows that dammed streams and created spring-fed lakes and channels. The area has long associations with local Indigenous people of the region and later was set aside for conservation to protect its water resources and native habitats.

The park sits in northeastern California near the small community of McArthur in Shasta County, on waterways tied to the Pit River drainage. The nearest larger towns are rural; the area is dominated by lakes, wetlands, and volcanic bedrock.

• Access: Most access is by water; there are no public roads into the main park area so visitors arrive by canoe, kayak, boat, or small aircraft.
• Landscape: The park protects a network of spring-fed channels, lagoons, and low basalt lava flows that create clear, slow waterways and wetland habitat.
