Cub Lake Trail

Overview

This classic meadow-to-lake hike starts at the Cub Lake Trailhead about 1.3 miles down Fern Lake Road on the west side of Moraine Park. The route crosses the Big Thompson River and meanders along the edge of broad, wildlife-rich meadows before climbing more steeply and rockily up to Cub Lake. Expect variety: open valley walking, pockets of forest and ponds, and a short, tougher finish to reach a small lake fringed in marsh and water lilies.

Distance, Elevation, and Options

Out-and-back to Cub Lake is 4.6 miles total (2.3 each way) with roughly 540 feet of elevation gain. A popular loop option runs about 6.0 miles with around 700–750 feet of gain: continue past the lake to connect with the Fern Lake Trail, pass river features like The Pools, then walk a short segment of Fern Lake Road to close the loop back to your car. The loop is scenic, but factor in the road walk or a shuttle connection.

What You’ll See

The first miles trace the western edge of Moraine Park—prime habitat for elk and mule deer, with frequent moose sightings near wetter areas. Near the lake you’ll notice a recovering burn landscape from the 2012 Fern Lake Fire: charred trunks mixed with vibrant regrowth, more open views, and seasonal wildflowers. Cub Lake itself is shallow and often carpeted in lily pads; it’s pretty and distinctive, but much of the shoreline is marshy with limited dry spots to sit.

Trail Feel and Who It’s For

It’s widely regarded as a moderate hike. The meadow sections are gentle and sunny; the final approach to the lake is the crux—rockier and steeper. Trekking poles help, especially on the descent. If you’re chasing big alpine cirques, this isn’t that; the draw here is wildlife, meadows, and a unique lily-pad lake with a flexible loop along a river.

Best Time to Hike

Summer is prime for lilies and wildflowers, but it’s also busy and exposed—start early for parking, cooler temps, and better wildlife activity. Fall brings aspen color and the elk rut (dawn and dusk are electric). Winter is a great off-season option if you’re prepared—expect packed snow or ice at times and bring traction or snowshoes as conditions dictate. Weekdays and early starts beat crowds year-round. Soft morning light is best for meadow photography; afternoons can be hot and buggy.

Logistics and Tips

Parking is limited at the Cub Lake Trailhead; in summer, the Moraine Park Shuttle serves the area (park at the Bear Lake Road Park & Ride). During peak season, timed-entry may be required to access this corridor by vehicle. No pets on this trail. If you’re planning an overnight on connected routes, backcountry sites (like Cub Creek or Arch Rocks) require advance reservations. Pack water, sun protection, and insect repellent (ticks are present; wear long sleeves/pants when possible and do periodic checks). Expect mosquitoes near the lake. In winter, carry layers, traction, and a simple emergency plan. If you do the loop, remember there’s a short road segment to finish.
