North Fork Trail to Kettle Tarn - 10.25 Miles Round-Trip
The North Fork Trail stretches 7.2 miles along the North Fork Big Thompson River from the Dunraven Trailhead in the Comanche Peak Wilderness Area to Lost Falls in Rocky Mountain National Park. Kettle Tarn fills a shallow depression in a bordering moraine 5.1 miles from the trailhead.
Hikers, runners and equestrians will enjoy miles of aspen-lined river banks, lengthy meadows, diverse forests, eleven backcountry campsites and renowned fishing along the North Fork Big Thompson en route to this interesting glacial feature.
The trail begins from the south side of the Dunraven Trailhead parking lot and drops quickly to the North Fork Big Thompson River (.35 miles : 7,670').
It turns upstream on a mild grade along its open, luxuriant banks. Well-spaced trees and deadfall clearings provide good viewing lanes for wildlife - notably deer, elk, bear and turkey - in this first mile.
The trail moves quickly to a second major bridge crossing (1.15 miles : 7,804'), passing for a short time through private property and a more crowded forest. It reaches a spur for backcountry campsite #1 (2.15 miles : 8,038') and crosses back on a sturdy bridge to the south bank.
The North Fork Trail continues easily to a side trail for horses and spur for backcountry campsite #2 (2.75 miles : 8,170'), just past which it crosses the river once more to the edge of a sloping meadow and spur to backcountry campsite #3 (2.8 miles : 8,175').
The trail now relaxes between the river and string of meadows, ponderosa parks and aspen stands for the next .65 miles, in which the next six backcountry campsites are located. This section is well-suited for picnics, fishing and wildlife viewing, and is a good turnaround point for shorter outings.
The trail passes backcountry campsite #9 (3.45 miles : 8,418') and inches up into a thicker forest. It turns abruptly north (3.6 miles : 8,482') and steepens on a markedly rockier path through uniform lodgepole before curling west and edging back toward the river.
The North Fork Trail moderates through a notably diverse forest to the Rocky Mountain National Park Boundary (4.35 miles : 8,934'), past which no dogs are allowed and anglers and backpackers must be cognizant of applicable regulations (described below).
A variously thin and diminutive forest offers a teasing glimpse of Mount Dickinson (11,831') and more distant peaks in the Mummy Range as it undulates to the Boundary Creek Backcountry Campsite (4.5 miles : 8,968'). The trail eases to the Kettle Tarn Backcountry Campsite spur (5.07 miles : 9,230'), which you'll follow over the river on an oft-slippery log bridge to the south bank.
A faint but intuitively followed path crests a moraine and drops to the open shore of Kettle Tarn (5.12 miles : 9,240'). The tarn is adjacent to a similarly shallow pond, both ringed by a generous, sandy shoreline that's easily explored.
