Tips from the Community
Brainard Lake is a beautiful alpine lake in the Indian Peaks Wilderness below the Continental Divide surrounded by subalpine forest. It is in the Brainard Lake Recreation Area, which during the summer season usually requires a reservation and a fee, but if you are on your bike you do not need to pay or reserve a time slot. Because of the area's high elevation, snow typically remains until late spring, even on the paved road to the lake.

If you're looking for a picturesque spot off the beaten path, you should definitely check out Red Rock Lake. At an elevation of around 10,500 feet, this hidden gem is often overshadowed by Brainard Lake, but it's worth a visit. The lake offers stunning reflections and vibrant colors, making it a photographer's paradise, especially during sunrise or after sunset. Red Rock Lake is located inside the Brainard Lake Recreational Area off the Peak to Peak Highway (Hwy 72) near Ward, CO. You can visit the area throughout the summer and into October without a fee if you are on your bike.

There is a sizeable parking lot here with restrooms. You can run up to Blue Lakes or Audubon and Paiute Peaks. The Blue Lake run is a great alpine trail run. The push up Audubon is a talus scramble but quite doable. The route over to Paiute is a dangerous loose ridgeline of the same talus and should not be attempted unless the weather is good and you have mountaineering experience.

Taylor Mountain is a fantastic, small mountain close to Allenspark. One huge benefit of this peak is that unlike in Rocky Mountain National Park, dogs are allowed on the trail. From the summit, which is marked by a stone cairn, you get great views of Mount Meeker, Meadow Mountain, and Twin Sisters Peaks. You can also traverse east to tag the summit of the neighboring Big John Mountain, but there is not an official trail so it can be a little hard to follow.

Brainard Lake Recreation Area is set in a glacially carved valley offering visitors spectacular panoramic views of Brainard Lake, surrounding subalpine forest, and high peaks along the Continental Divide. Because of the area's high elevation, snow typically remains until July.
