There are 3 main ways that you can access the Cabot Trail, after you cross the Canso Causeway.
Follow the rotary just after the causeway, towards Inverness and Cheticamp, route 19, Ceilidh Trail
Take the Trans-Canada-Highway #105, turn left onto the Cabot Trail, at the Red Barn Restaurant and Gift Shop, in Nyanza. (approximately 77kms from the Canso Causeway)
Take the Trans-Canada-Highway #105 through to St Ann’s, here you can travel by road past the Gaelic college or stay on the highway a few more minutes and cross by the English Town Ferry. Route 312 (approximately 110kms from the Canso Causeway)
This has got to be one of the best places on god’s earth. Pleasant Bay, the Hostel and staff included. Thanks for making my stay with you memorable.
