About Ahjumawi Lava Springs State Park

Ahjumawi Lava Springs State Park sits in remote northeastern Shasta County and can be reached only by boat, since no public roads lead to it and private motor vehicles are barred. Visitors launch onto Big Lake from a PG&E public ramp known as Rat Farm, reached from McArthur. Much of the land is covered by lava flows from the last several thousand years, including jagged black basalt. Clear aqua bays and small wooded islets line the shore, and freshwater springs run out of the lava along the water. The park has more than twenty miles of trails, but off-trail travel needs careful preparation. Wildlife such as bald eagles, ospreys, and mule deer are common, and the park offers views of Mt. Shasta and Mt. Lassen.
