Boulder to the Diamond: A Stunning Look at Longs Peak’s Most Iconic Face

The Diamond of Longs Peak rises in the distance — elevation 14,259 ft — as seen from this iconic trail sign viewpoint

Today’s Outdoor Picture of the Day brings you a breathtaking moment that perfectly captures Colorado’s alpine beauty—a rustic trail sign pointing the way to Longs Peak, with the Diamond Face rising dramatically in the background.

Visible from Boulder on clear days, Longs Peak is more than just a fourteener—it’s a symbol of Colorado’s rugged wilderness. Standing at 14,259 feet, it’s the highest summit in Rocky Mountain National Park, and one of the most recognizable peaks in the state. What truly sets it apart is the Diamond Face, a nearly vertical 900-foot wall of granite that attracts seasoned climbers from around the world.

While many Boulderites are familiar with the silhouette of Longs Peak from afar, few get to witness the mountain’s east face—known as the Diamond—up close. This photo captures that view in perfect clarity, with sunlight lighting up the rock and the blue Colorado sky providing the perfect backdrop. For outdoor lovers in Boulder, this is a reminder of the incredible mountain adventures just an hour’s drive away.

How to Get There from Boulder:

Getting to the trailhead is straightforward. Head north on Highway 36 through Lyons, then take Highway 7 toward Allenspark. You’ll see signs for the Longs Peak Trailhead, which serves as the main access point to the mountain’s popular Keyhole Route.

Even if you’re not planning to summit, the early miles of this trail offer spectacular views of the Diamond and surrounding peaks. It’s a fantastic day hike option for those looking to experience high-altitude terrain without a technical climb.

This part of Colorado also teems with wildlife and seasonal color—from golden aspens in the fall to wildflower-covered meadows in the summer. Whether you’re an experienced hiker or simply seeking a scenic escape, Longs Peak delivers.

From Boulder to the Diamond, the journey is short—but the view will stay with you forever.
