17 BUMPASS HELL PARKING AREA. The Bumpass Hell self-guiding nature trail, with explanatory leaflets provided enroute, is a 1.1 mile walk to the edge of the hot spring basin. This is Lassen’s most spectacular and diversified hydrothermal area. The walk through it involves another mile. In midsummer wildflowers are excellent along the trail: bog kalmia and Brewer mountainheath (low pink flowering shrubs), coast erysimum (orange), Newberry penstemon (red), and silverleaf lupine are the most conspicuous. Pinemat manzanita (white), rabbitbrush (yellow), and chinquapin (cream-colored) are dwarf shrubs which are also common.
