Diamond Lake Trail, located in Indian Peaks Wilderness, is a moderately challenging out-and-back hike with beautiful views of Diamond Lake and the surrounding peaks. Altogether, the hike is about 5.4 miles in length and gains roughly 1,220 feet in elevation.
Pro tip: make sure to check the weather frequently, as it can change very quickly in the mountains. The forecast the night before we hiked was clear but we ended up getting rained on about a mile into the hike and again during the last quarter mile! Which reminds me…
Pro tip: ALWAYS pack rain gear (if space/weight in your pack allows) – even if the forecast is clear.
The hike begins on Arapaho Pass Trail which departs from the end of Fourth of July Road, just past the town of Eldora. The trail will lead you gradually uphill through dense forests, until you reach a junction at about 1.2 miles, where you’ll bear left to begin on Diamond Lake Trail.
From here, the trail gradually descends, leading you over a creek crossing. After the creek, you’ll begin ascending once more until you reach Diamond Lake after about a mile. Diamond Lake offers lots of options for walking around and exploring the surrounding meadows!
After a few days of haze, the smoke has finally begun to clear and reveal the beautiful views Colorado has to offer. In celebration, I decided to venture over to Indian Peaks Wilderness for the first time and hike to Lake Isabelle.
Pro tip: the Brainard Lake Recreation Area that this hike is located in requires a timed entry reservation which you can acquire here.
Indian Peaks Wilderness is located along the Continental Divide and offers some of the most beautiful hiking in Colorado. Located about an hour west of Boulder, Indian Peaks Wilderness offers some fantastic day hikes and backpacking areas.
Indian Peaks is located about 2.5 hours from where I live in Colorado Springs, so I left town around 5:45am and made it to the parking lot just after 8am. The ranger at the entrance instructed me to park at the Brainard Lake Trailhead, though I later learned I could have continued on and parked at the Long Lake Trailhead. I didn’t mind parking at Brainard Lake because the walk from Brainard Lake to the Long Lake Trailhead was a good warmup, but it did add 2 miles roundtrip.
Long Lake was another beautiful sight as well, and I was hoping to see some moose or even a bear as the park ranger said there had been recent sightings, but I suppose they were all taking the day off because I didn’t see any wildlife.
The proper hike to Lake Isabelle, which begins at the Long Lake Trailhead, is fairly moderate, meandering along the edges of Long Lake before veering right and uphill to reach Lake Isabelle. The last half mile or so of the hike is fairly steep, though the views that soon emerge make it well worthwhile. Lake Isabelle itself was absolutely stunning, and you have plenty of options for exploring the shore of the lake and the surrounding meadows. The lake is framed by stunning peaks and the area was one of the most beautiful I’ve seen in the state.
The lake wasn’t too crowded by the time I arrived, but after stopping to rest and take some pictures, the hike back was fairly busy. All Trails reports the hike to be about 5.5 miles roundtrip with about 550 feet of elevation gain. I would say this hike is appropriate for new and experienced hikers, and there were lots of families when I went! Because of how popular this area can be, I would recommend visiting during the week or earlier in the morning on the weekend.
Pro tip: dogs are welcome but must stay on leash – there were lots of dogs when I went, and I even brought my own, Willie, but if you’re doing the same, please abide by the leash rules! There were several times unleashed dogs approached Willie and I, and though Willie is friendly, not every dog is. Plus, there’s always the chance you’ll see some wildlife, and even well-behaved dogs have been known to take off after other animals.
Overall, this was a gorgeous hike and I hope to return again soon. Let me know if you’ve hiked to Lake Isabelle yourself, and drop your recommendations for hikes in Indian Peaks Wilderness!
