The Credit River gorge at Forks of the Credit Provincial Park is a shale cut in the Niagara Escarpment with waterfalls on the river, the walk from Mississauga. Bruce Trail blazes show up on the posts along the loops from the lot, because the park is on the trail. You stay with the river on those loops until they bring you back to the lot.
Ontario Parks runs Forks of the Credit as day use only, with automatic entry gates and a permit bought ahead, as of September 2026. The van stays in the lot while you walk, and summer weekends fill that lot early.
Mississauga has no public campground of its own, so the night is the campground at Albion Hills Conservation Area in Caledon, a Brampton trip. If you need more sleeping space than a van, look at RV rentals in Mississauga.
Belfountain Conservation Area
The Credit is still in the picture at Belfountain Conservation Area, escarpment woods and connector loops that run toward the Forks. You can walk here and at the provincial park in one day, and you can start those loops from this trailhead. Caledon is the township around the trees.
Terra Cotta Conservation Area
Terra Cotta Conservation Area has its own loops on the same Credit River corridor and the Bruce Trail, and it still belongs to the walking day from Mississauga.
Port Credit and the Mississauga waterfront
On a day you stay in Mississauga, walk Port Credit's marina shore on Lake Ontario. Sailboat masts fill the marinas, and the path meets a shale beach where the lake starts. The Rattray Marsh boardwalk takes you out over the wetland on the same shore day. You can do this whole walk from a van that stays in the city.
Jack Darling Memorial Park is how those pieces connect on foot. The city's paved Waterfront Trail crosses the park and joins the walking trails in Rattray Marsh Conservation Area. The beach is unsupervised, and swimming depends on water-quality results.
Lakefront Promenade has a sand beach and a marina on the same waterfront pathway, with Lakefront Promenade Marina, Mississauga Sailing Club, and Port Credit Yacht Club nearby. You do not camp on this shore.
Bronte Creek Provincial Park is the Oakville overnight along the lake. If you want Algonquin, that trip starts from Toronto.
