Cub Lake Trail
Rocky Mountain National Park • Estes Park, Colorado
Overview
An easy hike through Moraine Park's meadows and aspen groves to Cub Lake, a small lily-pad-covered lake surrounded by pines. Wildflowers in July, fall colors mid-September, and one of the most beginner-friendly RMNP trails outside the Bear Lake area. The full route covers 4.6 miles round trip with about 540 feet of climbing, and most hikers finish it in around 3 hours. It sits in the Rocky Mountain National Park, near Estes Park in Larimer County, topping out at 8,620 feet.
Trail Highlights
How Hard Is It?
This is rated easy. The moderate-length 4.6-mile distance paired with steady 540 feet of gain is what sets the effort level. You hike out to the turnaround and return the same way, so you see the route twice and can turn back early without missing the payoff. The elevation stays low enough that altitude is not a major factor for most hikers. If you hike regularly, plan for roughly 3 hours of moving time; add a buffer for photos, snack stops, and the slower pace at altitude.
Best Time to Hike
The best seasons here are spring, summer, and fall. Summer is the reliable window once the snow clears, though that also means the busiest trailheads and the daily afternoon thunderstorm risk. In Colorado the weather turns fast in the high country, so start early, aim to be heading down by early afternoon, and watch the sky. Lightning, not distance, is what turns most summer hikes around.
Getting to the Trailhead
The trailhead is in the Rocky Mountain National Park, closest to Estes Park (Larimer County). You need a National Park entrance pass, and many park trailheads also require a timed-entry reservation in peak season. Check the park website before you drive out. The parking coordinates are 40.3562, -105.6158; plug those into your map app rather than the trail name, since several Colorado trailheads share names. Mountain weather and road closures can change access, so confirm the access road is open before a long drive.
Dogs & Kids
Dogs are not allowed on this trail, which is common inside national parks and sensitive alpine areas. Kids can handle it with breaks, especially given the 4.6-mile length. Bring extra snacks and water and let the pace be theirs.
What to Pack
Pack the Colorado basics: more water than you expect, layers for a 30-degree temperature swing, sun protection for the high-altitude UV, and rain protection for the afternoon. For a moderate-length, steady hike like this one, the gear that earns its weight most is comfortable footwear and a solid shell. Here is what we actually recommend for trails like this:
