The Diamond: Casual Route

The Diamond: Casual Route

There is only one 14,000 ft. Peak in Rocky Mountain National Park and it is Longs Peak. Being a stand alone 14,000 ft peak draw in large crowd’s on a year round basis. But, these crowds can be dispersed among the variety of hiking and climbing routes that Longs Peak provides.  But, the world famous alpine wall, “The Diamond”, holds many classic alpine climbing routes that people from all over the world travel to and climb.  The classic 5.10a Casual Route on Longs Peak, is the easiest route on the infamous Diamond, but this does not mean it should be taken for granted. This is a world class climb and listed as one of the 50 classic climbs. The Casual Route incorporates high altitude climbing with wild exposure and high alpine weather.

This 2 day outing climbs the Casual Route on Longs Peak in Rocky Mountain National Park.  We’ll hike in, bivy at Mills Glacier in the spectacular Chasm Cirque, then make an attempt to climb the most coveted rock route in Colorado.  This outing always runs at a ratio of one guide to one client.

Time: 2 days , 8am – 6pm and Alpine start to 5pm.
