About this program

The Department of the Interior National Park Service funds preservation, protection, and development of the National Trails System (CFDA 15.935) through cooperative agreements that emphasize volunteer involvement and partner engagement, with the most recent grant award issued on October 1, 2025.

The program finances trail operation and maintenance, resource protection, planning and trail development, interpretation and educational activities, and public outreach initiatives across National Scenic, National Historic, and National Recreation Trails. Funded activities include deferred maintenance projects such as facility rehabilitation (shelters, privies, bridges, parking areas), trail tread repair and erosion control, volunteer program coordination, interpretive programming and educational materials, disaster recovery work, geospatial data management, and visitor center operations. Recent awards reflect work on the Appalachian National Scenic Trail, Lewis and Clark National Historic Trail, Anza National Historic Trail, and other designated routes. The program also supports digital platforms, trail mapping, and initiatives that engage Tribal nations in cultural resource documentation and community-based workshops.

Cooperative Agreements comprise 97 percent of awards by count (520 of 534 total), with Project Grants representing the remaining 3 percent. The National Park Service Northeast Region leads funding concentration at $33.2 million in federal dollars across 96 awards, followed by the National Park Service (undifferentiated) at $15.5 million across 252 awards and the National Park Service National Office at $8.7 million across 53 awards. Eight distinct federal agencies participate in the program, though NPS dominates funding delivery.

Combined federal dollars obligated total $73.9 million across the portfolio, with combined total obligated (federal plus non-federal match) at $86.4 million. Award magnitudes span widely—from $10 thousand (pilot design projects) to $1.9 million (comprehensive trail association support). Representative recent awards include $1.85 million for the National Pony Express Association to enhance volunteer efforts on the Pony Express National Historic Trail; $1.52 million for Appalachian Trail disaster recovery following Hurricane Helene; and $904 thousand for cyclic maintenance and volunteer engagement along the Appalachian Trail.

The program has sustained activity over nearly two decades—the earliest award in the portfolio dates to June 2007—with recent annual output averaging 26–30 awards per year. No open competitive solicitations were identified in the most recent opportunities block; the listed opportunities are notices of intent to award to specific recipients, dating back to 2019–2020. Applicants include 501(c)(3) nonprofits, state and local governments, county governments, and Tribal entities. Pre-application coordination is strongly encouraged, and an environmental impact assessment is required for all projects.
