Ahjumawi Lava Springs State Park is one of California’s most remote and rewarding state parks, accessible only by boat — there are no roads in. Spanning nearly 6,000 acres along the shores of Big Lake and Horr Pond in Shasta County, this park protects a striking volcanic landscape where massive lava flows meet some of the largest freshwater springs in the country. Crystal-clear water bubbles up through the basalt at an astonishing rate, feeding the waterways that surround the park.

The name “Ahjumawi” comes from the Pit River people, meaning “where the waters come together,” and you’ll understand why the moment you arrive. The convergence of springs, rivers, and lakes creates exceptional habitat for bald eagles, ospreys, and great blue herons. Birding here is outstanding year-round.

Paddling is the primary way to explore — kayaks and canoes launch from Rat Farm Landing, about a 15-minute paddle to the park’s shoreline. Once on land, hiking trails wind through juniper woodlands and across dramatic lava fields dotted with ancient petroglyphs. Fishing for largemouth bass and crappie in the surrounding waters is excellent.

Primitive boat-in campsites are available along the shore, offering solitude that few California parks can match. Bring everything you need, including water.

Visit between late spring and early fall for the best conditions. Summer mornings are calm for paddling, though afternoons can bring wind. With just 36 reviews and a 4.1 rating, this park remains a genuine hidden gem for those willing to earn the experience.
