Cub Lake - 4.6 Miles Round-Trip
Cub Lake is a family-friendly, 3-4 season destination highlighted by the Big Thompson River, large elk herds in Moraine Park and vibrant autumn colors:
The trail heads south over Big Thompson River and undulates gently along the western fringe of Moraine Park, a vast meadow where glaciers once settled and receded, leaving a broad, level expanse in its place. Bordering ridges - called moraines - were formed by glacial movements that push churned land to its margins.
Today Moraine Park is braided by the Big Thompson River and Cub Creek, which give rise to bountiful grasses teeming with life.
Every fall large elk herds congregate in these food-rich meadows for their annual rut, a spectacular ritual where dominant bulls battle for mating rights. Mule deer gather in smaller numbers and are common throughout the year.
Smaller residents such as squirrels, voles, rabbit and hare attract larger predators such as coyote, fox, bobcat and raptors, while bears seek out autumn berries along meadows and streams for their long winter hibernation.
The trail reaches an unmarked split for South Lateral Moraine Trail and bends decisively west up valley (.55 miles : 8,095'). Small-medium sized ponds and thick grass beds dot the valley floor, ideal habitat for seeing elk. Well-spaced ponderosa, spruce, aspen and fir create good wildlife viewing lanes across the lower valley.
The trail moves quickly on a mild grade that steepens past 1.75 miles (8,285') and enters a thick aspen grove. Enjoy this colorful section from the trail, as the stream-laced forest floor is covered in ivy.
The winding trail relaxes on the edge of a marsh at the Cub Creek Backcountry Campsite spur (2.2 miles : 8,603'), and continues west to the northeast corner of Cub Lake (2.3 miles : 8,624').
Cub Lake is ringed by thick timber, limiting access and extensive exploration. Its east shore and outlet area are open but marshy. A social trail drops down to and traces the lake's north shore, while the main trail rises over the lake for .3 miles to the Mill Creek Trail junction (2.6 miles : 8,725'). Consider hiking to this point for additional perspective and better afternoon lighting.
Those seeking a longer outing may continue on to The Pool, Fern Lake or Mill Creek Basin. The Pool - a turbulent pocket below the convergence of Fern Creek, Spruce Creek and Big Thompson - is one mile from this point, and Fern Creek a more challenging 2.1 mile climb. A loop around Moraine Park can be made via the South Lateral Moraine Trail on the return.
