The section of the GHTA trail from the junction of the railway line and Brentwood Road (44.35386, -79.96300) to the junction Concession 3 and the railway tracks (44.35384, -7996378) follows an abandoned railway line. Railway ties and considerably overgrowth of shrubs tangled with vines makes numerous sections of this portion of trail very difficult to hike.
Maintenance of this section of trail is planned for the future, with the County of Simcoe considering transformation of the abandoned railway line into a multi-use trail (hopefully in the not-too distant future).
This trail section remains open for use, but the Mad River team wants hikers to be aware of the difficult hiking conditions.
