Horsethief Butte is a popular destination for rock climbers. Parking may be next to impossible on some spring days, despite the off-highway parking area. For botanists, one may view those species more common in the east end of the gorge, especially those that tend to like sandier soils. There is a vault toilet at the trailhead. A trail heads southwest from the trailhead and wraps around to the south side of the butte. A rough trail leads to the summit from the south side. Hikers with vertigo issues should be aware that the summit has 100' drops all around. A user trail can be followed along the south side and back around the east and north side of the butte.
The bluffs facing west over Horsethief Lake are a good place to set up a spotting scope to observe waterfowl on the lake during clear days in winter.
At nearby Horsethief Lake, one may picnic, swim, or camp. There are restroom facillities there, but that part of the park is closed to visitors during the winter. One may see a number of plants that like drier, sandier habitats around the periphery of the developed area. There are also some vernal ponds in the area to see species that live in such a habitat, but their access may be restricted......check with the park ranger first before visiting the vernal pools.
