Niwot Ridge - 10.1 Miles Round-Trip
The Niwot Ridge Trail climbs 1800' from the Long Lake Trailhead to a narrow, divisive ridge between the South St Vrain Creek and North Boulder Creek drainages. The latter is part of the Boulder Watershed, a string of six glacier-fed alpine lakes providing the balance of Boulder County's water supply. The Niwot Ridge Trail offers a rare glimpse down this secluded valley.
The Niwot Ridge Trail passes through the 1200 hectare Niwot Ridge Biosphere Reserve, established in 1979 for the study of alpine tundra. Visitors will enjoy diverse alpine landscapes, good trail conditions and arguably some of the best views in the Indian Peaks:
The trail follows a level path to the Jean Lunning Trail (.2 miles) and veers left over Long Lake's outlet. It continues clockwise to an unmarked split (left) for the Niwot Ridge Cutoff Trail (.4 miles : 10,558').
The trail enters a spruce forest at the base of Niwot Ridge and climbs methodically up its north face on long, winding switchbacks. This section is well-defined but can be obstructed by deadfall and snow.
The trail clears treeline (1.65 miles : 11,220') and moderates through open tundra to the first of two Niwot Ridge Biosphere Reserve markers (1.75 miles : 11,275'). Here it bends decisively south for a saddle in the lower, eastern portion of the ridge.
Behind you (north) are views of Longs Peak (14,259'), Mt Meeker (13,911') and Mt Audubon (13,223'); to the east a good look over Left Hand Park Reservoir. Look for ptarmigan, marmot, elk, moose, bighorn sheep and mountain goat in the open tundra.
The trail passes a second Niwot Ridge Biosphere marker (2.3 miles : 11,425'), crests on the ridge's saddle (2.6 miles : 11,460') and drops south to a 4x4 road. The valley ahead is part of the Boulder Watershed, a chain of lakes framed by Kiowa Peak (13,276') and Arikaree Peak (13,150').
The trail fades but is adequately marked by cairns to its convergence with the road and official Niwot Ridge Trail (2.9 miles : 11,407').
The road-trail rises steadily up the south-side of Niwot Ridge with great views across the open tundra and valley below. Watershed boundary markers and research facilities line the way for guidance.
In 4.1 miles the trail bends north for the ridge's high, narrow center with simultaneous views of the Watershed and South St Vrain Creek valleys.
Perennial snow clings to upper valley walls, the water system's primary benefactors. Navajo Peak (13,409'), Apache Peak (13,441'), Shoshoni Peak (12,967') and Isabelle Glacier (12,025') emerge to the west and north as the trail levels on the ridge top.
The trail reaches the last research post and cairn marking its unofficial end (5.05 miles : 12,285'). You may continue west to Navajo Peak and the Divide, or roll north for a look over the Isabelle Glacier valley. Honor the Watershed boundary, which extends all the way to the Divide.
