From the west:
If you are driving east across the island portion of the province on the Trans-Canada Highway, you can take Exit 35 onto Route 90, which will put you on the beautiful Irish Loop Route. This secondary highway takes you south to St. Mary’s Bay, around the southern rim of the Avalon Peninsula, and through Trepassey to the Edge of Avalon Interpretive Centre at Portugal Cove South. From there, the Irish Loop Route continues along Route 10 to St. John’s.
You can also choose to exit onto Route 13, the Witless Bay Line to Bay Bulls, where you can turn right on Route 10 and proceed to Portugal Cove South.
From St. John’s
You have two options when leaving St. John’s to visit the edge of avalon: you can take Highway 1 (the Trans-Canada) and take Exit 37 onto Route 13 as described above, or you can take Route 10 (known locally as the Southern Shore Road) all the way from St. John’s.
Trans-Canada, heading West:
You can gain access to Highway 1 West from any of the main roads heading out of St. John’s, including Torbay Road, Logy Bay Road, Portugal Cove Road, Allandale Road, Thorburn Road, Kenmount Road or Topsail Road. Look for the green maple leaf symbol with a “ 1” on it and be sure to take an exit for Highway 1 West.
Once on Highway 1, drive approximately 30 minutes to Exit 37 onto Route 13, the Witless Bay Line, which takes you to Bay Bulls on Route 10. There you turn right and follow the road signs for Trepassey. Approximately 1.25 hour’s drive on> will bring you to for the Edge of Avalon Interpretive Centre Portugal Cove South.
Southern Shore Road:
Water Street in downtown St. John’s is North America’s oldest street. It starts just one street up from the harbour apron, in the east end of the downtown below Signal Hill. Follow Water Street, heading west until you see signs directing you to Route 10. Route 10 takes you through the busy towns of Kilbride and the Goulds, which are now part of St. John’s. It gradually becomes more rural as it passes through Bay Bulls and Witless Bay. Road signs showing distances to Trepassey will keep you on track for the Edge of Avalon Interpretive Centre in Portugal Cove South. The drive will take approximately 2 hours and treat you to some extraordinary coastal scenery.
