Trails
Maroon Snowmass Trail: 21.6 Miles Round Trip | 6,640 Feet Elevation Gain | Class 3
This is really the only route to the summit of Snowmass (some alternate options explained below). It begins at the Maroon Snowmass trailhead through private property where hikers encounter 3 gates within the first 2 miles of the hike. Across the first two miles very little elevation gain occurs. Hikers simply remain on the Maroon Snowmass Trail which stays close to Snowmass Creek nearly the entire duration to Snowmass Lake.
Within the first 3-4 miles there are various dispersed campsites along the trail, some of which are traveled enough to appear to be the true trail but are not. Remember to simply take the trail that stays closest to the Maroon Snowmass Trail, except for 1.3 miles in when hikers reach the marked junction towards the West Snowmass Trail.
6.3 miles in, hikers will reach a log jam created at the end of a pond. Here, hikers cross the log jam to the other side of the water and follow the well established trail. In high water, the crossing is a little more difficult, but generally, the logs make for a pretty easy crossing. Be extra careful because it is easy to get a wet boot, or twist an ankle during this crossing.
8 miles in, hikers reach a junction that is well marked. Here, follow the signs and trails towards Snowmass Lake, not towards Geneva Lake or the Maroon Snowmass Trail.
8.3 miles in, and 2,580 feet higher from your starting point, you’ll reach Snowmass Lake and some absurdly stunning views. You can see the summit from here.
Cross the river leading out of the lake heading towards the south and east side of the lake. It is very easy here to head up the Geneva Lake Trail which you do not want to do. Follow the trail close to the lake so you’ll only rise 20 ish feet above the lake. If you start to rise 50-100 feet above the lake, you have gone too far to the left.
Hikers make there way around the lake and see the scree slopes heading up the gully towards the summit. The hike is difficult from here on out. Lots of scree, lots of boulders, lots of class 3 hiking.
The key to this entire section is to follow cairns all the way to the base of the last push to the summit. Simply follow cairns in the direction of the summit, though you can be off path a little bit without recognizing it. Just follow the easiest route for you.
Hikers have a choice of taking the direct route to the summit, which heads up steep scree and takes people to the ridge right near the summit, or taking a more stable rock approach and going around the left hand side. (Pictures below to describe this).
Our recommendation is to go up the left, and down the direct route scree field.
Alternate Routes
Hikers technically have the option to start at the Capitol Creek Trailhead or from the East Snowmass Trailhead. Both of which add a whole lot of miles and elevation gain. We don’t recommend this unless you are doing a backpacking trip and loop out to another trailhead.
Hikers also have two options for the last summit push. The direct route, or a loop around the left hand (southeast side) of summit ridge. (Pictures below should make this easier for you)

Hiking Snowmass Mountain in Winter
Snowmass is not an easy hike even in the best of weather. Add in some snow, and you can be in for quite a long day, and a bit of extra danger, not to mention the extra weight of gear you have to carry. However, snow may actually make this route a little easier to travel with the right conditions, plus, it makes the direct route to the summit a bit more accessible.
Camping For Snowmass Mountain & Lake
There are dispersed campsites near the trail at numerous points before hikers reach Snowmass Lake. The best sites are near Snowmass Lake where there are many of dispersed sites. Backpacking permits are necessary, and the area does have bears, so having proper bear equipment and storage is necessary.
