AAA Editor Notes
Lake Lenore Caves are 9 mi. n. of Soap Lake on SR 17. The caves formed on the east wall of Grand Coulee's basalt cliffs during Ice Age floods some 12,000 years ago. The site has 3 miles of hiking trails; an interpretive board at the trailhead describes the caves and their history. A gravel trail along a ledge leads to a series of caves in the cliff face, which provide nesting niches for swallows and swifts.
From the upper trail a sweeping view extends across Lake Lenore to the west wall of Grand Coulee. Archeologists have found small scrapers used to prepare animal skins, evidence that Native Americans once used the caves as temporary shelters.
Note: This is a large, unsupervised natural area; there is no ranger on site, and guided tours are not offered. Explore the area at your own risk and stay on the marked trails. As at other state parks in eastern Washington, be aware that rattlesnakes are active from late spring into fall.
Picnicking is permitted.
