Lassen Park Highway
CA 89Mineral to Manzanita Lake
A volcanic high road past steaming fumaroles and a lava peak.
CA 89 winds through Lassen Volcanic National Park beneath Lassen Peak, climbing past steaming sulphur vents, boiling pools and old lava flows to over 8,500 ft. Open only in the warmer months; mind the altitude, the late-lying snow, and stopping sightseers.
