Trail Description
"The Keyhole route in Rocky Mountain National Park is a climb that requires scrambling on exposed narrow ledges, loose rock and steep slabs. Sudden changes in weather may create high winds, lightening, rain, hail, snow, freezing temperatures and ice covered rock at any time. A slip, trip or fall could be fatal. Rescue is difficult and may take hours to days. Self-reliance is essential. Stay on route and be willing to turn around at any point. Safety is your responsibility." ~ NPS
This warning, posted at the Boulderfield, should be heeded by anyone attempting this hike/climb.
Plan to start your hike at about 1-3 am in order to reach the summit and be down below treeline before the afternoon thunderstorms. 
How to Get There
