In 1912, reformatory prisoners built this wooden trestle bridge over the Eramosa River from Douglas fir logs transported by train from British Columbia. The Guelph Hiking Trail Club will lead 30-minute 400-metre walks (1,300 feet) (on demand) from 10 a.m. until 3:30 p.m., visiting the Guelph Escarpment and the dry-stone walls around the remnants of Guelph's original 1908 oak aqueduct.
