Free: 1 Leslie St, Toronto · Season: year-round
Tommy Thompson Park, universally known as the Leslie Spit, is one of the most extraordinary urban wilderness areas in the world — a 5-kilometre artificial peninsula jutting into Lake Ontario, built from construction debris and lakefill over decades, now transformed into a thriving ecosystem that supports over 300 bird species, mammals, reptiles, and extraordinary plant communities. Completely free, open weekends and holidays, and offering some of the most dramatic lake views in Toronto, the Leslie Spit is a genuine wilderness experience minutes from downtown.
What to Expect
The Leslie Spit was never intended to be a park. It began in the 1950s as a dumping ground for construction debris, earth, and dredged material from Toronto harbour projects. Over decades, the peninsula grew to over 500 hectares, extending 5 kilometres into the lake. Nature colonized the rubble — grasses, shrubs, trees, birds, insects, and mammals all found a home on this accidental island.
In the 1970s, the public began accessing the spit, and the Toronto and Region Conservation Authority (TRCA) recognized its extraordinary ecological value. Today, it is managed as an urban wilderness park, with limited public access to protect the wildlife while allowing visitors to experience one of the most important bird habitats on the Great Lakes.
The spit is wild. There are no paved paths in the natural areas, no facilities beyond the entrance, and no services. You walk on dirt trails through tallgrass prairie, shrub thickets, and along the rocky lake shore. The city skyline looms behind you, but ahead is open water, wild vegetation, and the sounds of birds.
Wildlife
The Leslie Spit is one of the most significant bird habitats in eastern North America:
Birds: Over 300 species have been recorded. The spit is a critical stopover for migrating songbirds, waterfowl, and shorebirds. Spring migration (April-May) and fall migration (August-October) are peak birding times. Common sightings include warblers, sparrows, ducks, geese, herons, and birds of prey.
Mammals: Coyotes, red foxes, rabbits, raccoons, and muskrats all live on the spit. The coyotes are particularly notable — a small population hunts the abundant rabbits and rodents.
Reptiles and Amphibians: Several species of turtles, snakes, and frogs inhabit the wetlands and ponds.
Butterflies and Insects: The wildflower meadows support abundant insect life, including monarch butterflies during migration.
The Trail
The main trail runs the full length of the spit from the entrance gate to the lighthouse at the tip. The walk is approximately 10 kilometres round-trip and takes 3-4 hours at a leisurely pace with stops for viewing and photography. The trail is unpaved — dirt, gravel, and occasionally muddy. Sturdy footwear is essential.
Along the trail, you pass through distinct ecological zones:
- **The entrance area:** shrub thickets and young forest
- **The prairie section:** tallgrass meadows with extraordinary biodiversity
- **The lake shore:** rocky beaches and open water views
- **The wetlands:** ponds and marshes teeming with life
- **The tip:** the lighthouse and 360-degree lake views
The Lighthouse
The tip of the Leslie Spit features a small lighthouse and breakwater, offering 360-degree views of Lake Ontario, the Toronto skyline, and the distant shorelines. This is one of the most dramatic viewpoints in the city — open water in three directions, with the towers of downtown framed by lake and sky.
Seasonal Highlights
Spring (April–May): Peak spring migration. Warblers, sparrows, and waterfowl pass through in extraordinary numbers. The wildflower meadows begin to bloom. This is the best season for birdwatching.
Summer (June–August): The spit is lush and green. Resident birds are nesting. Butterflies and dragonflies fill the meadows. The lake is warmest for swimming (though there are no lifeguards and swimming is at your own risk).
Fall (September–October): Peak fall migration. The meadows turn golden. The lake is often calm and beautiful. This is the second-best season for birding and arguably the most beautiful time on the spit.
Winter (November–March): The spit is open on weekends and holidays year-round. Winter birding can be excellent, with waterfowl congregating in the harbour. The landscape is stark and beautiful. Dress very warmly — the wind off the lake is severe.
How to Get There
The Leslie Spit entrance is at the foot of Leslie Street, south of Lake Shore Boulevard East. The 83 Jones bus from Pape Station stops nearby, or you can walk/cycle from the Distillery District or the Waterfront Trail. Limited parking is available at the entrance. The spit is only accessible on foot — no vehicles, bicycles, or dogs are permitted beyond the gate.
Accessibility
The Leslie Spit is not wheelchair accessible. The trails are unpaved, uneven, and can be muddy or sandy. The walk to the tip and back is 10 kilometres and requires reasonable fitness. There are no benches, washrooms, or water fountains along the trail — bring everything you need.

Photography Tips
The Leslie Spit offers extraordinary photography opportunities. The lighthouse at the tip with the skyline behind is the classic shot. Bird photography requires a long lens (300mm minimum recommended). The wildflower meadows in summer are beautiful for macro work. The juxtaposition of wilderness and industrial cityscape is compelling. Morning light is best for the east-facing lake shore.
