CHALLENGING DAY HIKE
12.7 miles 1,450' elevation gain
An excellent long loop hike through varied terrain.
Two fords of the largest creek along the Lassen hikes provide some excitement, but be careful, flowing water can be dangerous. The crossing at the 3-mile point is probably the harder one, and gives you a chance to turn back if the water is too high.
The namesake Grassy Swale is a special treat to Pacific Crest Trail hikers more accustom to dry ridges and stiff climbs, it is lovely, green, gentle, and water-blessed.
Twin and Swan Lakes aren't too bad either :-)
is in Lassen National Park; owned by the public, managed by Lassen
National Park. Backpacking at least 200' from water, no campfires,
bear-proof food storage, in-person self-service permit from any Park
