Chicago Lakes is a pair of alpine lakes nestled beneath the flanks of Mount Evans in Clear Creek County, consistently rated as one of the most beautiful hiking destinations in Colorado. The trail passes through varied terrain — from forested slopes and cascading waterfalls to alpine meadows filled with columbine wildflowers — before arriving at a lower and upper lake surrounded by towering mountain walls. With a 4.9 rating from visitors, this is a hike that delivers on its reputation.
The trail begins near Echo Lake, which is a scenic destination in its own right. From there, the path to Upper Chicago Lake takes roughly two hours and 15 minutes at a steady pace, with the return trip taking about an hour and a half. The hike is classified as difficult, with steep sections that challenge even experienced hikers, particularly the final push to the upper lake. Some stretches are mentally demanding for those uncomfortable with heights, and the climb back out at the end tests endurance. Bringing plenty of water is essential, and hikers should plan to take their time on the steeper pitches.
Wildlife is abundant along the Chicago Lakes trail. Visitors report sightings of moose, mountain sheep, mountain goats, and diverse wildflowers, especially during late summer when hills of columbine are in full bloom. The lakes themselves sit in a dramatic cirque setting with mountain peaks as a backdrop, creating scenery that multiple visitors describe as among the best they have encountered anywhere in Colorado.
The trailhead parking lot fills early — by 8:00 AM on weekends, roadside overflow parking is already in use. Arriving before 8 AM is advisable to secure a spot. The trail gets busy after 9 AM during summer months. Wind can be strong at the lake level, so packing a wind layer and rain jacket is recommended. Late summer is the ideal window for visiting, as earlier in the season snow can block portions of the trail.
Camping is possible in the area, though there are no designated campsites with facilities. Fishing is available at the lakes during summer. The trail can also be accessed from the top of Mount Evans by descending to the upper lake, a steep and rocky route that does not require climbing gear but demands caution. The diversity of terrain, spectacular alpine scenery, and accessible trailhead near Echo Lake make Chicago Lakes a must-do day hike for anyone exploring the Mount Evans corridor.
