Swimming & Beach.
Innisfil Beach Park runs about 50 acres on Cook's Bay at the foot of Innisfil Beach Road in Alcona — the largest municipal lakefront park on Lake Simcoe and the centre of the town's identity as a Lake Simcoe waterfront community. The long sand swimming beach is the flagship; Belle Ewart Beach a short distance south adds a second town-managed swim.
The brief.
Cook's Bay is shallower than Kempenfelt Bay's deep central trough to the north, so summer water at the swim beach warms earlier and stays in the upper teens to low 20s through July and August. Innisfil Beach Park is a day-use park with paid in-season parking for non-residents; the grounds carry three boat launch ramps, a marina, a splash pad, sports fields, and picnic shelters alongside the beach.
The Lake Simcoe Region Conservation Authority regulates shoreline activity within 120 metres of the lake under the Lake Simcoe Protection Plan, including any development at the shore. Best season is July and August for warm-water swimming; June and September are shoulder swims with cooler water.
Belle Ewart Beach is the smaller, quieter alternative.
