Longs Peak Conditions (as of September 12, 2014)

Conditions in Rocky Mountain National Park can change at any time.

Please take appropriate gear to endure these changing conditions. Also, be prepared to turn around when conditions exceed your abilities.

Remember your safety is in your own hands.

Longs Peak Trail

The Longs Peak Trail is dry all the way to the Boulderfield. The trail may still be covered in some places by standing water, especially after severe rain and thunderstorms.

Keyhole Route Conditions

Currently, the route past the Keyhole is wet and has substantial sections of snow and ice. In particular, the Ledges and Trough have the most snow and ice. These current conditions are making travel more difficult for visitors. Projected temperatures and weather for the week will likely lead to the persistence of snow and ice on route. Snow and ice are unavoidable while on route. Please be prepared for these conditions.
