This provides a short cut to paddle to the west, instead of paddling around Cape Sable Island . This can also be used as an exit or launch if you want to paddle around Cape Sable  Island. Just across the causeway at North East Point is another good access.
Barrington Passage gives the paddler a lot of choices for stocking up on supplies if you are doing an extended trip. If there is something you especially need for your kayaking trip inquire at any one of the local stores. If you want to stretch your legs for awhile take time to walk the Barrington Bay Trail accessible at the causeway.
