Gem Lake Hike

Lumpy Ridge Trailhead

The hike to Gem Lake starts at the Lumpy Ridge Trailhead. This trailhead is located just north of Estes Park. To get here, you will take Devils Gulch Road to Lumpy Ridge Road. You will not pass a park ranger booth to get to the trailhead.

Next to the trailhead are toilets. Two trails start at this trailhead. Go right to hike to Gem Lake. The trail to the left is the Lumpy Ridge Trail.

Hiking to Gem Lake

From the trailhead, it is an uphill walk almost the entire way to Gem Lake. Some sections are rather steep and you need to be prepared to hike up long staircases made from giant rock steps. This is a short hike but it is tiring. It will have you stopping to catch your breath occasionally.

The trail starts climbing immediately. Over the 1.7 miles to get to Gem Lake, you will be hiking in and out of the forest and along giant granite boulders and walls.

Occasionally, the trees will break and you will be treated to wonderful views of Estes Park. There is one wide clearing, about halfway up the trail, where you get amazing views of Estes Park and Rocky Mountain National Park.

The final third of this hike is the hardest. The trail gets steeper and through most of this section you will be hiking up and over large rock steps. It’s tiring on the way up but it can also be tough on the way down, since the steps are so large. If you have bad knees, consider bringing hiking poles to help you on the way back down the trail.

The trail ends at Gem Lake. The water that fills this lake is from snowmelt from the cliffs and higher land that surround the lake. There is no stream or river leading into or out of this lake.

Walk around the lake for photos. There is a sandy, beach-like area on the western side of the lake. During our visit, kids were climbing and playing on top of the cliff walls that surround the lake.

If you want to go further, you can continue on the trail until you reach Bridalveil Falls and the Twin Owls Loop.

Tips to Have the Best Experience

Even though it is a tough hike, this is a good trail to hike with kids. We saw kids as young as 5 and 6 at Gem Lake, playing on the rocks.

Trail updates. As you plan your trip to Rocky Mountain National Park, and just before doing this hike, check the National Park Service website for updates on trail and road closures.

What to Bring on the Hike

Hiking shoes or a good pair of walking shoes. As long as there is not snow on the ground, a good pair of walking shoes or running shoes are sufficient. The trail is rocky and uneven but hiking shoes are not necessary for this hike.

Sunscreen, hat, and sunglasses. For most of the hike you will be walking through a forest but once at Gem Lake you will be exposed to the sun.

Camera. Even a smartphone will do. For great photos of the trail and the mountains, use the panorama feature of your smartphone.

Hiking poles. Due to the steep nature of this trail, hiking shoes are beneficial if you suffer from any knee or leg pain on hikes with steep descents or stairs.

Mosquito repellent. There can be mosquitoes, primarily around the lake. When we did this hike in early July, we did not encounter any mosquitoes, but I have read other trail reports of mosquitoes in the summer months.
