Endless Mountains Gravel Bikepacking Loop (EMGBL), in Bradford, Sullivan, Susquehanna, and Wyoming Counties, is an adventurous 430-mile cycling route winding through the scenic landscapes of northeastern Pennsylvania. It offers riders a blend of challenge and exploration. About 65% of the route is gravel or dirt, with the remaining portion on quiet paved roads. Riders experience over 42,000 feet of elevation gain, tackling varied terrain that tests endurance and skill. The loop brings riders to or near five state parks, a state forest, and the Susquehanna River North Branch Water Trail. Guided by wayfinding and interpretive signage, cyclists can explore charming small towns, heritage sites, and local eateries, adding a cultural dimension to the ride. The availability of diverse lodging options makes the loop suitable for multi-day bikepacking trips. To accommodate a more diverse group of cyclists, 15 to 20 shorter loops are incorporated. The EMGBL, the first official bikepacking loop in Pennsylvania, was the brainchild of a Sullivan County cycling enthusiast who formerly served as County Commissioner and Endless Mountain Heritage Area board member. With her encouragement, the Heritage Area teamed with county tourism agencies, the Northern Tier Regional Planning and Development Commission, and several avid cyclists to bring the project to fruition. Challenge events have attracted riders from Pennsylvania and beyond. The EMGBL has become an economic driver for the rural communities throughout the region and a symbol of endurance and exploration.
