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.

What Makes It Special

High-alpine setting with a glacially carved basin; native trout ecology including Yellowstone Cutthroat and Rainbow Trout; otters seen during spawning season

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.

Safety Considerations

Bear spray required; maintain 100 yards from bears and wolves and 25 yards from other wildlife; steep ascent and muddy lakebed demand caution; no natural safety barriers around the lake; water is perpetually cold

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.
