Halverson Lake is a strange and lovely destination in the Snake River canyon south of Melba, Idaho, a small desert lake tucked beneath rimrock cliffs and tall sand dunes, reached by a walk through some of the most geologically odd country in the state. The trail starts at Celebration Park, Idaho's only archaeological park, and follows the Snake River before branching off to the lake, which makes this one of those rare hikes where the walk in is as interesting as the destination.

The landscape is the reason to come. Melon rocks litter a fairly barren, wide-open scene: these are melon gravel, boulders rounded and scattered by the catastrophic Bonneville Flood, and they give the whole area an otherworldly look. The lakes themselves are depressions ringed on one side by lava tube cliffs, and the Halverson Bar and Lake area is unique for its curving two-mile sandbar along the Snake River paired with two shallow lakes sitting below the rimrock. Halverson Lake covers about 13.4 acres and takes its name from brothers Al and Roy Halverson, who once farmed property to the north.

The hike is moderate and manageable: about 3.8 miles with only 147 feet of elevation gain, taking most people an hour to an hour and a half. Usefully, the first mile follows a gravel road, so you can drive that section and cut the walk substantially if you'd rather spend your time at the lake. The trail hugs the Snake River bank before turning off toward the water.

Celebration Park itself is worth the trip alone, with petroglyph-covered boulders recording thousands of years of human presence in the canyon, plus interpretive programs and a historic bridge. Climbers find routes on the basalt, and the area is popular with horseback riders as well as hikers.

This is exposed high-desert canyon country with essentially no shade, and summer heat here is serious, which is why spring and fall are far better seasons than July. Rattlesnakes are genuinely present, so watching where you put hands and feet among the rocks is worth the habit.

Bring more water than a four-mile hike suggests, sun protection, sturdy shoes for the rocky ground, and a camera for the melon rocks and rimrock. Between Bonneville Flood boulders, lava tube cliffs, ancient petroglyphs, a two-mile sandbar and a quiet desert lake at the end, Halverson is one of the most interesting short hikes in southwestern Idaho.
