Chasm Lake lies nestled in a rocky alpine cirque below the towering summits of Longs Peak (14,255 feet) and Mount Meeker (13,911 feet), the two highest summits in Rocky Mountain National Park. Chasm Lake is accessible from the Longs Peak Ranger Station and Trailhead. The Longs Peak Trailhead is on the east side of the Continental Divide between Estes Park and the village of Meeker Park. Longs Peak Road provides access to the trailhead from Colorado Highway 7. Turn west on
to Longs Peak Road from Highway 7 at a junction approximately 9 miles south of Estes Park, or 2 miles north of Meeker Park. Look for a left (south) turn to the trailhead parking area, about 1 mile from Highway 7, where Longs Peak Road continues straight (west) to the Longs Peak Campground. Parking is very limited and the lot fills up early in the summer season.  About 3.5 miles from the Longs Peak Trailhead, the Chasm Lake Trail splits from the Longs Peak Trail and heads south. This 0.7 mile trail to the lake heads downhill to a creek crossing just above Columbine Falls. Just beyond a Park Service patrol cabin, the trail disappears in the rock slabs, but routes to the lake are marked with cairns. Most of this trail is above timberline, so special attention must be given to weather conditions. Large snowfields near the lake may persist into summer months, and should be crossed with extra caution.

This lake is found at the base of Longs Peak in the Rocky Mountain National Park.  It is usually fishable from June to October. There is a hitch rack and toilet at the beginning of the trail. Horses are not permitted on this trail. Chasm Lake is at N40°15.520' Latitude and W105°36.208' Longitude with an elevation of 11,760 ft. 

Chasm Lake is one of the most beautiful alpine lake in Colorado.  Fishing for cutthroat trout is rated fair.  The lake is deep with rocky edges. The closest campgrounds to the lake are Goblin's Forest (1.2 miles one-way from trailhead) - 6 individual sites and Battle Mountain (2.8 miles one-way from trailhead) - 1 group site.

This list is intended as a guide only and no responsibility is taken for any incident arising from mis-information. The ultimate responsibility as to whether the trail is safe to travel, within the capabilities of yourself and your vehicle, or indeed open at all, is taken by YOU.
