Discover 934 campgrounds in Ontario — from provincial and national park sites to private RV parks and municipal campgrounds: 185 provincial, 9 federal, 733 private and 7 municipal.
Ontario has the largest provincial park system in Canada — Ontario Parks runs 340 parks, with reservable sites at over 100 of them. Algonquin alone has eight major car-camping campgrounds. Reservations open 5 months in advance through the Ontario Parks Reservation Service and the most popular sites (Bon Echo, Killbear, Sandbanks) sell out at the moment of opening.
Algonquin Provincial Park is the spiritual home of Canadian camping. Paddle a canoe into the interior on routes that Tom Thomson and the Group of Seven painted a century ago — the autumn colour here is legendary, with sugar maples turning every shade from gold to crimson. For car campers, Mew Lake and Pog Lake campgrounds offer easy access to wolf howls (the park runs guided events in August) and morning mist rising off still lakes.
Killarney Provincial Park on Georgian Bay is often called Ontario's most beautiful park, and it's hard to argue. The white quartzite ridges of the La Cloche Mountains contrast with sapphire-blue lakes, and the backcountry campsites on George Lake and OSA Lake feel like private retreats. Nearby, the town of Killarney serves the best fish and chips in Northern Ontario — the Herbert Fisheries restaurant is a pilgrimage for paddlers.
Southern Ontario surprises with Sandbanks Provincial Park's massive freshwater sand dunes on Lake Ontario — the largest baymouth barrier dune formation in the world — and Prince Edward County's wine region next door. Bon Echo Provincial Park's 100-metre cliff face covered in Ojibwe pictographs is best seen from a canoe at sunrise. And for families, Killbear on Georgian Bay has warm shallow water, smooth rock sunbathing, and some of Ontario's best stargazing.
Northern Ontario is the province's wild secret. Pukaskwa National Park on Lake Superior's north shore offers some of the most rugged coastal hiking in Canada — the 60 km Coastal Hiking Trail and backcountry sites at Hattie Cove are reserved months in advance. Lake Superior Provincial Park's Agawa Rock pictographs, painted by Ojibwe artists hundreds of years ago, are accessible from a short coastal scramble. And the vast network of Crown Land in Northern Ontario means free dispersed camping is genuinely abundant for those willing to drive past the busy southern parks.
For RV travellers and big families, Ontario's private resort campgrounds add a dimension Sépaq and provincial systems don't cover. The Trent-Severn Waterway corridor, the Thousand Islands and the Niagara Peninsula host hundreds of full-service parks with pools, mini-golf and on-site activities. Pair a few nights at one of these with a wilderness night at Algonquin or Killarney for a varied itinerary that suits every member of the family.
Season: early May – mid-October · Reservations: Ontario Parks Reservation Service — 5-month rolling window
Ontario's camping geography is staggering — from Lake Erie sand dunes to subarctic Hudson Bay. Most campers stick to four core regions.
The classic Ontario canoe-tripping wilderness. Front-country campgrounds along Highway 60 plus 2,000+ km of interior routes.
Granite shorelines and Canadian Shield lakes within 2–3 hours of Toronto. Books up faster than anywhere else in the province.
Turquoise water, white limestone cliffs, the Grotto. Reserved year-round, day-use needs a separate vehicle pass in summer.
Wild, rugged, gloriously empty. Lake Superior's coastline rivals anything in the Maritimes for sheer drama.
| Month | Weather | Crowds | Notes |
|---|---|---|---|
| May | 10–20 °C, blackfly hatch begins mid-month in the north | Low | Most parks open Victoria Day. Algonquin interior still cold for swimming. |
| June | 18–25 °C, blackflies peak first 2 weeks | Moderate | Lakes warming up. Bug nets mandatory in Algonquin. Cottage country fills by mid-month. |
| July | 22–28 °C, humid | Peak | Reservation window opens 5 months ahead — set an alarm. Lake swimming at its best. |
| August | 23–28 °C, thunderstorm risk | Peak | Bruce Peninsula needs a same-day vehicle reservation just to enter. Plan ahead. |
| September | 12–22 °C, no bugs, clear nights | Moderate | Arguably Ontario's best camping month. Fall colour in Algonquin peaks last week. |
| October | 5–15 °C, peak fall colour | Low | Most electric sites stay open until Thanksgiving. Pack a 0 °C bag minimum. |
Five months ahead, to the day. So a July 15 arrival opens for booking at 7am Eastern on February 15. Popular sites sell out in seconds.
Many smaller and Northern Ontario parks (Esker Lakes, Rene Brunelle, Restoule on weekdays) have walk-up availability. Algonquin's interior canoe sites are reservable but rarely sell out outside July long weekend.
Basic car-camping sites are $42–$48/night, electrical sites $50–$60. There's also a daily vehicle permit ($14–$22) on top of camping fees.
Free camping on Crown Land is allowed for Canadian residents (up to 21 days at a single location) in most of Northern Ontario. Non-residents need a Crown Land Camping Permit.
Killbear, Pinery and Bon Echo are widely considered Ontario's best entry-level campgrounds: well-serviced, easy car access, swimming beaches, comfort-station washrooms and active interpretive programs. Reserve at least 3 months ahead for July and August.
Yes. Dogs are welcome at all Ontario Parks campgrounds on a maximum 2-metre leash. Most parks have dedicated dog beaches and pet-friendly trails — check individual park pages, since a few have pet-restricted loops.
Generators are restricted to specific quiet hours (typically 8am–10am, 12pm–2pm and 4pm–7pm) and are banned outright in most radio-free or quiet campgrounds. Many electrical sites make generators unnecessary anyway.
Late June through early September is peak season. For autumn colour, the last two weeks of September into the first week of October at Algonquin and Killarney are spectacular and far less crowded — but bring warmer sleeping bags.
Yes — anyone aged 18 to 64 fishing in Ontario needs a valid Outdoors Card and a fishing license, available online from the Ministry of Natural Resources. Camping permits do not include fishing rights.
Most Ontario Parks campgrounds accommodate RVs up to 12 metres (40 ft), but specific loops vary. Use the 'site finder' tool when booking and filter by 'maximum vehicle length' to confirm your rig fits before you arrive.
Yes — about a dozen Ontario Parks offer year-round camping, including Algonquin (Mew Lake), Killarney, Pinery and MacGregor Point. Yurt and cabin rentals are popular alternatives for cold-weather trips.
