The high mountain pass of Highway 89 allows easy access to the summit of Lassen Peak. The 2.5-mile (4 km) trail to the summit begins from a parking lot on the highway. The trip to the peak and back is a total of five miles (8 km) with a climb of about 2,000 feet (610 m). The average time for the round trip is 3-5 hours. The elevation of the trail is from 8,000 feet (2,430 m) to 10,457 feet (3,187 m) so care should be taken if you are not used to high altitudes.
