What is the highest hill in Ontario?

The highest point in Ontario is Ishpatina Ridge, in the Temagami area of northeastern Ontario, at about 693 metres (2,274 feet). It's not a hill most people hike — there's no developed trail to the summit, and it's reached by canoe and bushwhack. For hikers, the highest point in a provincial park is Silver Peak in Killarney Provincial Park, at 543 metres. Blue Mountain has the highest vertical drop of any Ontario ski resort, at 220 metres.

Can you hike the Bruce Trail in sections?

Yes, and most people do. The Bruce Trail is over 890 km long end to end, and only a small number of hikers complete it in a single trip. The trail is divided into nine sections, each managed by a local Bruce Trail Club, and each section can be hiked in day trips or overnight trips. The Bruce Trail Conservancy publishes the Bruce Trail Reference guidebook, which is the standard map and description for section hiking. An end-to-end hike typically takes 4 to 6 weeks.

Do you need a reservation for Dundas Peak?

Yes, during the fall foliage season and on most summer weekends. Spencer Gorge Conservation Area, where Dundas Peak is located, uses a reservation system managed by the Hamilton Conservation Authority. Reservations open in late summer and the fall slots sell out within days. You book a time slot in advance and pay the day-use fee and parking fee as part of the reservation. Outside the reservation period, you can pay at the gate, but the lot still fills on weekends.

What is the best time of year to hike in Ontario?

September and October are the best months for hill hiking in Ontario. The weather is cool, the bugs are gone, and the hardwood forests are in fall colour. Late September is peak colour in Algonquin and the La Cloche Mountains; early to mid-October is peak on the Niagara Escarpment. July and August are the most reliable for backcountry trips in the north, but they're hotter, more crowded, and buggier in the first half of summer.

Is Sleeping Giant Provincial Park worth the drive?

If you're already in the Thunder Bay area, yes. The Top of the Giant Trail is one of the best day hikes in Ontario, with cliff-edge lookouts 250 metres above Lake Superior. The park is about 40 minutes from Thunder Bay, so it's a realistic day trip from the city. If you're coming from southern Ontario, it's a 15-hour drive or a flight to Thunder Bay, so it's a trip to plan around rather than a side trip.

Are the pictographs at Bon Echo accessible?

The pictographs on Mazinaw Rock are best seen from the water. Bon Echo Provincial Park rents canoes at the lake, and the park also runs a boat tour along the cliff face during the summer season. You can see some of the pictographs from the Clifftop Trail above, but the main viewing is from a canoe or boat. Do not touch the pictographs — the red ochre is fragile and touching is prohibited under provincial and federal law.

Can you camp at these parks?

All of the provincial parks in this guide have camping. Killarney has a car campground at George Lake and backcountry sites reached by canoe or hike. Bon Echo has car camping at the Main Campground and backcountry sites on the lake. Sleeping Giant has car camping at Marie Louise Lake and backcountry sites. Blue Mountain has resort lodging but no camping. Spencer Gorge, Rattlesnake Point, and Mount Nemo are conservation areas with day-use only, except for a small walk-in campground at Rattlesnake Point. Reservations for provincial parks open in March and fill quickly for summer weekends.

Do you need a permit to hike in Ontario provincial parks?

Yes, you need a day-use permit for any provincial park, even for a day hike. The permit is paid at the gate when it's staffed, or online through the Ontario Parks day-use permit system when the gate is unstaffed. For backcountry overnight trips, you need a backcountry permit reserved in advance through the Ontario Parks reservation system. Conservation areas (Spencer Gorge, Rattlesnake Point, Mount Nemo) charge a separate day-use fee managed by the local conservation authority.

When most people picture Ontario, they picture the lake country — Algonquin, Muskoka, Georgian Bay, the Great Lakes shoreline. But Ontario's geography is also defined by ridges, cliffs, and escarpments that produce some of the best hill hiking in eastern North America. The province sits across two major geological features: the Canadian Shield, the ancient bedrock that covers most of the north, and the Niagara Escarpment, a long ridge of sedimentary rock that runs from Niagara Falls all the way to the Bruce Peninsula. Between them, they create the elevation, the lookouts, and the cliff-edge trails that make Ontario hill country worth the trip.

This guide covers the best hills, hiking spots, and scenic hill destinations in Ontario — from the province's highest ski resort to a giant of stone lying on Lake Superior. It's written for people who want to actually get out and walk, not just look at a view from a parking lot.

## Blue Mountain (Collingwood)

Blue Mountain is Ontario's largest ski resort, and for most southern Ontarians it's the first hill destination that comes to mind. It sits on the Niagara Escarpment near the southern shore of Georgian Bay, in the town of The Blue Mountains, just west of Collingwood and about two hours northwest of Toronto by car.

### The numbers

Blue Mountain Resorts Limited was established in May 1941, which makes it one of the older ski operations in Canada. The resort spans 147 hectares (about 360 acres) of skiable terrain with a vertical drop of 220 metres (720 feet). As of 2024 the resort maintains 43 named runs, including its four terrain parks. The top elevation is 450 metres (1,480 feet). It is the largest ski resort in Ontario by vertical drop and skiable acreage, and it draws the biggest crowds of any hill in the province.

### What to do

In winter, Blue Mountain is a ski and snowboard mountain first. The 43 runs are served by a network of lifts, and the resort has night skiing on a good portion of the terrain. The pedestrian village at the base — a faux-Alpine cluster of hotels, restaurants, and shops — is where most of the après-ski activity happens. It's busy, it's commercial, and it's not for anyone seeking solitude, but it's the most convenient ski-in/ski-out setup in Ontario.

In summer, the resort flips into a downhill mountain biking and scenic gondola operation. The Ridge Runner Mountain Coaster runs year-round, and there's an open-air gondola that takes visitors to the top of the escarpment for views over Georgian Bay. The surrounding area — Collingwood, Thornbury, Craigleith — is a weekend destination in its own right, with cideries, breweries, and apple orchards in the Beaver Valley to the south.

### When to go

Ski season typically runs from mid-December through late March or early April, depending on snow and snowmaking. January and February are the coldest and most reliable months. March brings longer days and softer snow but bigger weekend crowds. Summer and fall are the resort's second high season, especially on long weekends. Fall colour on the escarpment here peaks in early to mid-October.

### Practical notes

- **Getting there:** About 2 hours from Toronto via Highway 427 north to Highway 26, or via the GO Transit weekend bus to Blue Mountain in season.
- **Lift tickets:** Buy online in advance for the best rates. Walk-up window prices on peak weekends are the most expensive in Ontario skiing.
- **Parking:** Paid lots in the village; off-site lots with shuttle service on peak days.

## Sleeping Giant Provincial Park (Thunder Bay Area)

If you want a hill that doesn't feel like a resort, drive 50 miles east of Thunder Bay to Sleeping Giant Provincial Park. The park takes its name from a formation of flat-topped mesas that, seen from across
