Trout Lake

Natural Attr★★★★☆

Overview

About This Attraction

The loop trail circles Trout Lake, tracing the shore with open views toward Soda Butte Creek valley. The lake sits in a high alpine basin at the base of the Absaroka Mountains. Glacial ice carved the basin during the Pleistocene, later filled by meltwater and precipitation. This landscape records glacial history within a volcanic frame—glacial processes carved the basin, and volcanic uplift continues to shape the surrounding terrain.

Best Time to Visit

Late spring through early fall. Mornings bring softer light and calmer water. From mid-June to early July, trout spawn, and the lake sees higher activity and more visitors to the nearby trails. The fishing season opens Memorial Day weekend.

Visitor Tips

  • Start early to secure parking; the small trailhead fills during peak season.
  • Bear spray is essential; maintain distance from bears and wolves.
  • Winter traction devices and warm clothing are advised for the ascent.
  • Carry sufficient water; no potable water at the trailhead or lake.
  • Stay on the shore if venturing near the lakebed, which can be muddy and treacherous.
