The peak may be reached by either of two trails which lead to the Boulder Field, the highest point on the climb to which horses may be taken. The east trail, which begins near Longs Peak post office, 9 miles south of Estes Park, winds up the slope of Battle Mountain, passes timberline at an elevation of more than 11,000 feet, swings to the crest of Mills Moraine, overlooking Chasm Gorge, then skirts the slope of Mount Lady Washington, goes through Granite Pass, and leads to the shelter cabin in the center of the Boulder Field, at an elevation of 12,700 feet, a distance of 6 miles.
From Glacier Gorge Junction on the Bear Lake Road, the north trail winds its way up the north slope of the peak through the great burn of 1900 and joins the east trail at Granite Pass, a mile and a half below the Boulder Field cabin. The distance to the Boulder Field by this trail is 9 miles.
From the Boulder Field cabin the ascent to the summit may be made by either of two routes. The north face route, which is the shorter, climbs the precipitous north side of the summit, skirting along the rim of the east precipice, with magnificent views down the sheer drop of 1,200 feet into Chasm Lake in the gorge below. The Longs Peak climb includes the hazards usual to any major mountain ascent. Visitors are cautioned that use of the assisting cables on the North Face route is at their risk and the Government is in no way responsible. The other route leads across the Boulder Field to the Keyhole, half a mile distant and some 500 feet higher, where there is a small storm shelter.
On passing through the Keyhole, one sees the imposing Front Range, and 2,000 feet below the Glacier Gorge. To the left there is a narrow, steeply inclined ice-filled gulch, called the Trough. Finally, after what is to the amateur often an exhausting climb, one passes along the Narrows, up a steep incline known as the Homestretch.
The trip to the Keyhole is well worth while for those who do not care to climb Longs Peak, but who do wish to see at close range the rugged grandeur of the mountains. Another splendid foot trip from the Boulder Field cabin is to Chasm View, half a mile distant, where one sees the precipitous east face of Longs Peak, from the summit down to Chasm Lake, 2,500 feet below.
Chasm Lake
One may ride on horseback almost to Chasm Lake. The view from here is magnificent, and the upper gorge is one of the most impressive in the park. Both Chasm Lake and the Keyhole may be visited in a day. This is an exceptionally fine trip, and if horses are used it is not difficult.
Wild Basin
The splendid Wild Basin area south of Longs Peak and east of the Continental Divide is dotted with lakes of superb beauty in a sublime mountain setting. It is entered from Copeland Lake by an unimproved road up the North Fork of St. Vrain Creek, which soon lapses into a trail. From mountain tops on the south may be had unsurpassed views of the snowy mountains. The largest lakes of Wild Basin—Thunder Lake and Bluebird Lake—are both above timberline but are easily accessible by trails.
