The Tomifobia Nature Trail is a multifunctional 19-km rail-trail located in the Tomifobia River valley, between Rte. 141 in Ayer’s Cliff, and Rte. 247 in Beebe (Stanstead), Quebec. It lies in the heart of the Eastern Townships’ natural and architectural heritage site. Sentiers Massawippi, a non-profit membership organization and a registered charity established in 1990, created the Tomifobia Nature Trail on an abandoned railway right-of-way, in 1993. Open year round to bikers, hikers, joggers, snowshoers, birdwatchers, fat bikes, cross-country skiers and dogs on a leash.
