Cathedral Lake isn’t just a destination—it’s an experience that captures the heart of Aspen’s alpine beauty. This 5.6-mile round-trip hike is as challenging as it is breathtaking, winding through aspen groves, cascading streams, and rugged switchbacks to one of Colorado’s most pristine mountain lakes.
The trail begins just beyond the quaint town of Ashcroft, at the Cathedral Lake Trailhead. From the first steps, the dense canopy of aspen trees surrounds you, their golden leaves glowing in fall or vibrant green in summer. The path climbs steadily, with each turn revealing more of the Elk Mountains’ grandeur. Soon, you’ll hear the soothing sound of Pine Creek rushing alongside the trail, its cool waters adding a refreshing touch to your ascent.
As you climb higher, the trail becomes steeper and more rugged, winding through a series of rocky switchbacks that demand both strength and focus. But the effort is rewarded tenfold as you crest the final rise and Cathedral Lake comes into view. Framed by dramatic peaks and jagged cliffs, the turquoise waters shimmer like a jewel set in the Rockies. It’s the kind of sight that makes every mile worth it.
The lake’s shores are the perfect spot to rest, soak in the views, and enjoy a well-earned snack. For those feeling adventurous, a scramble up the nearby ridges provides even more stunning vistas of the surrounding wilderness. As you make your way back down, the descent offers a new perspective on the trail’s beauty, leaving you with a deep appreciation for the rugged charm of Aspen’s high country.
The hike to Cathedral Lake is a 5.6-mile round-trip journey through the White River National Forest, offering stunning alpine scenery and a challenging but rewarding climb to one of Aspen’s most beautiful high-altitude lakes.
