Twin Owls Loop: 11.05 miles

Lumpy Ridge Trailhead

Description

The Twin Owls Loop circles and scales Lumpy Ridge, a massive granite rock complex located in the northeast section of Rocky Mountain National Park. Passing through ponderosa woodlands, montane forests and lower-subalpine communities, The Twin Owls Loop is quietly one of the most ecologically and terrestrially diverse trails in the Park. This lengthy and lightly traveled loop is highlighted by good wildlife viewing opportunities, sweeping views, summer wildflowers, mature aspen groves and exceptional autumn foliage.

Traveling clockwise from the new Lumpy Ridge Trailhead Parking Lot is recommended for a more solitary experience. Note that, regardless of which way you travel, the trail begins outside Park Boundaries and staying on the designated trail is a must.

Traveling clockwise, the trail rises and drops along the southern slope of Lumpy Ridge. It reaches the National Park Boundary in .6 miles and access for Gem Lake just a few steps away. The trail winds through sculpted boulders and mixed forest to the former Twin Owls Parking Lot, through which it quickly passes and splits left down the Black Canyon Trail (.75 miles).

The trail drops through a gorgeous, open south-facing valley with panoramic views of the Continental Divide. A good map will help you identify many prominent peaks such as Longs Peak (14,259’), Estes Cone (11,011’), Taylor Peak (13,163’), Powell Peak (13,208’) and McHenrys Peak (13,327’). It bypasses climbing access points (The Book Area: 1.55 miles, The Pear: 1.87 miles), enters a dense ponderosa forest (2.0 miles) and re-enters the Park Boundary through a gate after 2.1 miles (7,990’).

Here it begins a steady, unapologetic climb to the Black Canyon Trail Junction (3.88 miles : 9,092’). Note how ponderosas are gradually replaced by lodgepole pines as you gain elevation. Bear right at the Black Canyon Trail split (towards Cow Creek Trailhead) to continue the loop. The trail reaches its max elevation at the 4 mile mark (9,134’), after which it begins a moderately steep descent through aspen stands to the north side of Lumpy Ridge.

The north side of Lumpy Ridge is a broad, verdant valley. Cow Creek – lined by notably tall and dense aspen stands – cuts through its center. Look for deer, elk, fox, coyote and turkey moving about the hillsides. The trail gently drops through the valley to the Gem Lake junction (6.5 miles : 8,135’).

The Peregrine Backcountry Campsite (5.55 miles : 8,330’), a creek crossing (5.65 miles : 8,292’) , Bridal Veil Falls Trail junction (5.7 miles : 8,278’) and Rabbit Ears Backcountry Campsite (6.34 miles : 8,134’) are all passed en route. Follow signs to Gem Lake.

The trail undulates through commingling aspen, ponderosa, lodgepole, spruce and fir to the final crossing of Cow Creek (6.7 miles : 8,057’) and the base of Lumpy Ridge, where it begins an arduous climb to Gem Lake. A mostly unforgiving grade yields excellent views of the valley below and frequent glimpses of the distant Mummy Range, where the formidable summits of Mount Ypsilon (13,514’) and Fairchild Mountain (13,502’) rise above the northwestern horizon.

The trail momentarily eases on a verdant plateau and remains flat to the Balanced Rock Trail junction (8.15 miles : 8,665’). From here the trail abruptly drops and rises over uneven terrain to Gem Lake (9.4 miles : 8,830’), which fills a shallow granite depression atop Lumpy Ridge. Expect small crowds at this popular destination. A rough trail drops quickly from Gem Lake through pretty aspen and ponderosa stands for the final 1.65 miles to the trailhead (11.05 miles : 7,870’).

Worth Noting

The trail’s lower elevations and far-east location make it an ideal 3-4 season hike, with autumn being an especially nice time of year to visit.

Bridal Veil Falls is a worthwhile 1.9 roundtrip excursion if time permits. Be cognizant of time and approaching weather, as you must climb through higher, exposed elevations on the return to Lumpy Ridge Trailhead.

The Twin Owls Loop passes through transitional ecosystems, which typically host a greater abundance and diversity of wildlife.

Trailhead Information

To reach the Lumpy Ridge Trailhead: From US 36 in downtown Estes Park, drive north on MacGregor Avenue. Shortly after crossing US Highway 34, MacGregor Avenue will turn into Devils Gulch Road. Continue on Devils Gulch Road bypassing the gateway to the MacGregor Ranch area. Less than a mile ahead, the turn off to the trailhead is marked by an NPS sign. Turn left (north) onto the trailhead access road which dead ends several hundred yards from Devils Gulch Road. The trailhead and parking area have pit toilets.
