Longs Peak Winter Conditions Advisory
Winter conditions have taken over in the high country of Rocky Mountain National Park. Any venture beyond the trail head will require route-finding skills, proper winter equipment, and knowledge of winter travel. Travelers should expect to encounter cold temperatures, snow and ice, avalanche hazards, and high winds. Winter routes are not marked and often vary from the established summer trails. Periods of excellent weather do occur, however they are short lived and backed by long periods of intense winter conditions. Also, be prepared to turn around when conditions exceed your abilities. Remember, safety is your responsibility.

Regular reports on the Keyhole Route on Longs Peak will be posted from June through September.

Remember your safety is in your own hands.
