Swimming & Beach.
Elora Quarry Conservation Area is a former limestone quarry now operating as a designated GRCA swim area with cliff backdrops; Rockwood's swimming hole sits in a glacial pothole bowl on the Eramosa; and Byng Island carries a Grand River beach near the Lake Erie mouth at Dunnville. Three different watershed swim features — quarry, pothole, river beach — within a short drive of each other.
The brief.
Elora Quarry has timed entry on busy summer days; arrive early or off-peak to be sure of access. Rockwood's pothole swim is small and crowds quickly on hot weekends.
Byng Island's beach is gentler and family-oriented near the river mouth. Swimming season is roughly mid-June through early September; the GRCA gates each area, with day-use fees and capacity rules.
Spring runoff makes the river itself unsafe for swimming until levels drop, generally by late May or early June.
