Slopes of Mount Bross with Mine Opening

USFS Adds Mount Bross Land to National Forest, but the Summit Remains Closed

PARK COUNTY, Colo. — March 20, 2026

A long-running Colorado access issue just shifted in a meaningful way. On March 18, the U.S. Forest Service announced that 480 acres on Mount Bross have been permanently added to the Pike-San Isabel National Forests, expanding public ownership on a heavily used stretch of the DeCaLiBron Loop near Alma.

The acquisition matters because the DeCaLiBron Loop — the popular route linking Mount Democrat, Cameron, Lincoln, and Bross — has been shaped for years by a patchwork of private land, liability concerns, and changing access agreements. The newly acquired parcel includes a section of the route on Mount Bross and is intended to support public trail access while also protecting wildlife habitat and critical headwaters in the South Platte basin.

But hikers should not read this as a full reopening of Mount Bross. The actual summit remains privately owned, and legal access to the top is still not permitted. In other words, this is a real public lands win, but not a green light to leave the designated route or trespass in hopes of claiming the summit.

According to the Forest Service, the purchase was made from The Conservation Fund, which acquired the property in 2025 as part of a larger effort to stabilize long-term access and protect the alpine landscape. The deal builds on an earlier 2023 acquisition that helped secure other parts of the DeCaLiBron area, including land near Kite Lake and portions of the loop on nearby peaks.

The Forest Service said the parcel will be managed for public trail access as well as resource protection. Partners involved in the broader effort have emphasized that the land also helps conserve alpine tundra, wildlife movement corridors, and headwaters that support downstream communities. Funding came through the Land and Water Conservation Fund, which receives permanent support through the Great American Outdoors Act.

For Colorado hikers, the practical takeaway is simple: access on the DeCaLiBron Loop is more secure than it was before, but Mount Bross is still not a completely open peak. That distinction matters. This is exactly the kind of situation where outdated GPX files, old blog posts, or word-of-mouth beta can give people false confidence about what is and is not legal on the ground.

It also underscores a larger lesson about recreation in Colorado’s high country. Access is not static. It depends on landownership, stewardship, local partnerships, and the willingness of hikers to respect boundaries. When visitors ignore closures or wander off-route, they do more than risk a bad day — they can make already fragile access situations harder to preserve over the long term.

For anyone planning a DeCaLiBron trip this year, the best move is to verify current access before you go, stay on the designated trail, and avoid treating the Bross summit as open just because more of the mountain is now public. The mountains are inherently unpredictable, and access on complex private-public landscapes can be just as important to check as weather, gear, and turnaround time.
