CONSTRUCTION ALERT AT (GAP mile 10) associated with the slide repair. Construction is underway and all bike traffic will need to exercise caution and walk their bike around the construction area (i.e. between the track rails). The area will be fenced off and barricades will be placed at the east and west ends of the site. Detour signs will be placed on the barricades indicating a right and left detour respectively. Construction equipment will be utilizing the trail from the Woodcock Hollow trailhead to the construction site. The heavy equipment will impact the trail and most likely kick larger stone onto the trail. All riders must be aware of the construction activity and use caution in this area. Construction is anticipated through mid-April. The grass shoulders and bike trail will be restored to equal or better condition at the conclusion of the project.
The Paw Paw Tunnel of the C&O Canal (C&O mile 155) requires the temporary closure of the north (downstream) tunnel portal and towpath. The project will involve assessing, removing or "scaling" loose and unstable rock, and then pinning solid rock to increase stability above the towpath. We are excited that this work will begin in late February! During the project a portion of the towpath at the north or downstream end of the tunnel will be closed to all users. A less steep bypass trail will be signed directing thru-bikers and hikers to the top of Tunnel Hill then connecting with the existing trail. Hikers will be able to continue to use the entire Tunnel Hill Trail during the project. Please see the attached FAQ for the project.
APR 7 2017 | Water & Restroom Facilities
There are chemical toilets at the campgrounds and GAP access areas, but limited potable water, especially since the NPS is no longer treating the pump water at the hiker/biker campgrounds. Carry at least a quart of water more than you think you need. Take advantage of towns along the way for water resupply.
