Athabasca Pass

When exposed at low tide, this rock bridge connects a dog-friendly beach to a strangely shaped island.  

Built by a local resident to help keep feet dry when passing to an off-shore island, Athabasca Pass magically appears at low tide. From Sand Street Beach—a public dog-friendly spot with a handful of wobbly, warped docks—you may journey over to locally-known “Half Dolphin Island” (for the way it looks from above when exposed).

From here, there are beautiful views of the bay and Gamecock Cottage. It is possible to venture over to that beautiful green gabled historic spot and Trustees Road at low tide, thanks to this hidden passageway.

The pass remains open at spots to allow water and organisms to continue to flow freely. As such, these gaps should remain open at all times. Feel welcome to add a personal rock to the blocked sections, leaving a memory of your visit to this beautiful landscape.

Know Before You Go

Get free parking at Sand Street Beach, and then walk along the shore until you see it. Remember to go at low tide!


Enjoy the West Meadow Wetlands from a new angle! Bring a kayak in the summer or some gloves and a ball for your dog in the winter.
