Ashbrigde's Bay is the start of the eastern Beaches--which are far superior, at least as beaches for swimming, volleyball, etc., to the western beaches. The park runs along the beach areas, as does a boardwalk. The easternmost kilometres of the Martin Goodman bike trail run through the park, and it's the most pleasant part of the trail to ride through in the entire east end.
At the west end of Ashbridge's Bay is huge water treatment plant, which can really put the whiff of sewage in the air if the wind picks it up. Something to keep in mind if you're thinking of joining the Ashbridge's Bay yacht club.
