A Nationally Recognized Trail Under the BOLT Act
The Maah Daah Hey (MDH) Trail is one of only 10 trails nationwide selected for inclusion in the federal BOLT Act, a designation that recognizes its exceptional recreational value and economic impact. This recognition puts the MDH Trail on a short list of iconic long-distance trails eligible for targeted federal support, helping ensure its long-term sustainability. Being chosen underscores the trail’s importance not just to North Dakota, but to the broader outdoor recreation community across the country.
Why Bikes Are Restricted in TRNP Wilderness Areas
While the MDH Trail passes near Theodore Roosevelt National Park (TRNP), it’s important to understand that bicycles are not permitted in designated Wilderness Areas within the park. These restrictions are part of federal Wilderness Act regulations, which limit mechanized travel to preserve natural conditions and wildlife habitat. As a result, mountain bikers cannot legally ride through the TRNP Wilderness sections, creating a discontinuity for riders attempting to complete the full MDH Trail experience.
Working Toward a North Unit Bypass for Bikers
The Save the Maah Daah Hey (STMDH) organization is actively working on a solution to address this gap by developing a safe, legal bypass around the TRNP North Unit. The goal is to maintain trail continuity for cyclists while respecting federal land-use regulations and conservation priorities. This effort involves coordination with land managers, stakeholders, and local partners to create an alternative route that preserves access, safety, and the overall integrity of the MDH Trail experience.
