unknown national parks Lassen
Lassen Volcanic National Park, Calif.

Yosemite and Death Valley may be California's two most iconic national parks, but relatively remote Lassen is well worth your visit, too. It's home to wide wildflower-filled meadows and, as its name implies, an active volcano, Lassen Peak. Daring visitors can make the three-mile trek to and from Bumpass Hell; aside from its evocative name, Bumpass thrills with hot springs, steam vents and rainbow-like soil formations colored by sulfur.
