The Greenbrier River Trail (GRT) has two “Friends” groups dedicated and actively engaged in promoting, preserving and improving the Trail. First, the Greenbrier River Trail Association (GRTA) that has been in existence for more than 40 years and was largely responsible for establishing the Trail. In June 2020, the Greenbrier River Trail Foundation (GRTF) was formed by members of GRTA. By creating a state park foundation, GRTF has access to WV State Park matching grant funds used to expand Trail improvement projects.
GRTF and GRTA share the same governance, Board structure, officers, bylaws and operations. Both groups are dedicated to fostering trail health and vitality and work closely with the WV Division of Natural Resources (DNR) which oversees regular maintenance, grant and volunteer opportunities, and annual trail events. Finally, both groups are 501 (c) (3) organizations and continue to support the needs of the GRT.
