Trailhead: Longs Peak Trailhead (Longs Peak Ranger Station)
Activities: Hiking, Camping Map
Closest City / Town: Estes Park, Colorado
Hiking Distance: 14 miles (roundtrip)
Description: At 14,259 feet tall, Longs Peak should not be climbed by individuals who fear heights. This hike is probably the most classic trek in Rocky Mountain National Park. One of this site's authors has climbed Longs Peak five times and has seen people in dire straits. Although the Keyhole Route isn't terribly technical, certain portions (such as the narrows) can really scare the pants off people.
You must possess basic bouldering skills to pass through the Keyhole and the chokestone in the Trough. If you attempt Longs Peak, be sure to allocate the whole day to the climb - hit the trail early in the morning. Moreover, bring plenty of water and food. The last thing you need is to be tired, without fuel in your body.
Also, do not attempt to travel beyond the Keyhole if bad weather is approaching. Storms can build and move quickly through Rocky Mountain National Park. Many people have lost their lives by attempting to summit Longs Peak during poor weather.
Worth Noting: The view from the privies is one of the best in the Rockies. If you've "got to go," there is no better place to do it.
