As temperatures begin to rise across Ontario, families looking for an affordable summer getaway will soon have access to Canada’s largest outdoor swimming pool.
The massive pool at Byng Island Conservation Area is scheduled to open for the 2026 summer season on June 20 and will remain open daily until Labour Day on September 7.
Located near the community of Dunnville, approximately two hours southwest of Toronto, the pool covers an impressive 1.85 acres and can accommodate up to 1,000 swimmers at a time. The facility features both shallow swimming areas suitable for children and a deeper section equipped with a diving board for more experienced swimmers.
Operated by the Grand River Conservation Authority, the pool will be open seven days a week from 11 a.m. to 6:30 p.m., weather permitting.
The conservation authority encourages visitors to consider weekday visits when possible, as midweek days generally offer lighter crowds, easier parking, and more room to enjoy the water.
The pool is one of the main attractions within the 190-hectare Byng Island Conservation Area, a popular destination known for its scenic natural surroundings where the Grand River flows toward Lake Erie. Visitors can enjoy Carolinian forests, wetlands, riverfront landscapes, and a variety of outdoor recreational activities.
Admission remains affordable for families. Day-use entry to the conservation area costs $9.50 for adults, $4 for children aged four to twelve, $7.50 for seniors and persons with disabilities, while children three years of age and under are admitted free. Access to the pool requires an additional fee of $3 per person for guests aged four and older.
Beyond swimming, visitors can take advantage of a wide range of recreational opportunities. The conservation area offers camping facilities, hiking trails, cycling routes, picnicking areas, wildlife viewing opportunities, and watercraft rentals including kayaks, canoes, and paddle boats. Complimentary lifejackets are available both at the pool and with watercraft rentals.
Nature enthusiasts can explore several walking trails within the park, including the Creekside Trail, Carolinian Trail, and Pines Trail. Together, the trails provide approximately two kilometres of scenic pathways through forests and wetlands.
A visit to Byng Island can easily be combined with a trip to nearby Dunnville, a picturesque riverside community where the Grand River meets Lake Erie. The town offers restaurants, specialty shops, historical attractions, and waterfront scenery that make it a popular day-trip destination for Ontario residents.
Local attractions include the historic Port Maitland Lighthouse and the No. 6 RCAF Dunnville Museum, which celebrates the region’s aviation heritage.
With its combination of swimming, outdoor recreation, nature trails, camping, and nearby attractions, Byng Island remains one of Ontario’s most unique summer destinations. For families seeking a fun and affordable way to cool off this season, Canada’s largest outdoor pool is once again ready to welcome visitors.
