Indian Heaven Wilderness, Nature reserve in Skamania County, United States.

Indian Heaven Wilderness is a federally protected wilderness area on a forested plateau in Skamania County, Washington State. It lies within Gifford Pinchot National Forest and is scattered with volcanic peaks, along with a large number of lakes, ponds, and wetlands spread across the high country.

Congress designated this area as wilderness in 1984, giving it formal protection under federal law. Before that, it had been used by Indigenous peoples for an extremely long time, long before European settlers arrived in the region.

For thousands of years, Native tribes traveled to this highland each season to fish, hunt, and gather berries. The name "Indian Heaven" itself reflects this long history of use by Indigenous peoples, whose connection to the land is still recognized today.

The Pacific Crest Trail passes through the area and connects most of the lakes and ridges, making it the main route for exploring on foot. Once inside, there are very few facilities, so visitors should come prepared for changing mountain weather and self-sufficient travel.

The Indian Heaven volcanic field covers 230 square miles and holds about 60 eruptive centers on a 19-mile fissure zone trending N10°E. Its volume is roughly 20 cubic miles, and it forms the western part of a larger 770-square-mile Quaternary basalt field in the southern Washington Cascades. Big Lava Bed records the most recent activity, about 8,200 years ago.
