Lassen Peak from Lake Helen
Lassen Peak is a small volcano but large enough to have Lassen Volcanic National Park. A tourist trail climbs easily 2.5 miles from the main park road to the summit. Unfortunately, only a week before we climbed, a family was hit by falling rocks and a teen was killed. This is surprising as the majority of the route is on a ridge and safe from any dangers. Since this mountain was erupting in 1914-1916, the summit crater looks quite active. Lassen is the 9th highest Cascades peak and also on the Ultra 57 prominence list.

The Route: Your online resource for hiking, climbing and travel
Follow the main road through the park to the highest point in the road. The signed trailhead and massive parking lot will be obvious.
Follow the easy trail up to the summit. Interpretive signs are placed along the whole route. After the fatal accident, the trail was closed halfway up. Check with the park to see if it has re-opened. Since this is a quick climb, be sure to hike Bumpass Hell, a nearby trail to the best hydrothermal area in the park.
