If you drive north from Toronto on Highway 400, Simcoe County is the first region that feels like you have left the city behind. Barrie appears about 90 minutes in (less without traffic, considerably more on a Friday afternoon in July), and from there the county fans out westward toward Georgian Bay, northward to Orillia, and along the Highway 26 corridor to Collingwood and Wasaga Beach. It is the most visited part of Southern Ontario outside the GTA, and for good reason: the geography ranges from Lake Simcoe's flat agricultural shore to the Niagara Escarpment's ski hills and Georgian Bay's rugged coastline.
Barrie: The Gateway
Barrie is the county seat and by far the largest community, with a population around 150,000. It has GO Transit commuter rail service to Toronto's Union Station, a waterfront trail along Kempenfelt Bay, and the kind of retail and services you would expect from a mid-sized city. For many visitors, Barrie is simply the last stop for groceries before heading further north. But the downtown has improved over the past decade, and the lakefront is genuinely pleasant for a walk or a summer afternoon.
Barrie is also where Highway 400 traffic converges, which means it bears the brunt of the Friday evening and Sunday afternoon cottage rush. Plan accordingly.
Collingwood and Blue Mountain
Collingwood, about 45 minutes west of Barrie on Highway 26, has transformed from a quiet shipbuilding town into one of the most popular four-season destinations in the province. Blue Mountain Resort, just outside town, is Southern Ontario's main downhill ski area, with a season running from early December through late March. The Blue Mountain Village at the base is busy but commercial; the better dining and shopping are on Collingwood's Hurontario Street, where the downtown has filled with restaurants, brewpubs, and independent shops.
In summer, the area pivots to cycling (the Georgian Trail runs from Collingwood to Meaford along the bay), golf, and the scenic caves. The Collingwood Elvis Festival in late July is a genuinely strange and entertaining weekend. Parking in the village area on winter weekends and summer long weekends is a known frustration; arrive early or walk from town. For local listings and community information, the guide at collingwood.net is a useful resource.
Wasaga Beach
Wasaga Beach has 14 kilometres of freshwater sand along Nottawasaga Bay, making it one of the longest freshwater beaches in the world. In summer, the main beach areas (Beach 1 and Beach 2) draw enormous crowds, with tens of thousands of visitors on hot weekends. The atmosphere at the main strip leans toward fast food, ice cream, and beach gear shops. Further along the shore, Beaches 4 through 6 are quieter and more suited to families.
The town has been working to redevelop the beachfront area for years, with mixed progress. Off-season, Wasaga is very quiet. More at wasagabeach.net for local updates and visitor information.
Stayner and Clearview
Between Barrie and Collingwood, the Township of Clearview includes the small towns of Stayner, Creemore, and New Lowell. These are agricultural communities, quieter and less tourist-oriented than their neighbours. Stayner has a compact main street and serves as a service centre for the surrounding farmland. Creemore, home to the Creemore Springs brewery, draws weekend visitors to its single-block downtown. The local community guide at stayner.com covers Stayner and area, and clearview.ca has information for the broader township.
Midland and Penetanguishene
At the southern end of Georgian Bay, the twin towns of Midland and Penetanguishene are the gateway to the 30,000 Islands and Georgian Bay Islands National Park. Midland is home to Sainte-Marie among the Hurons, a reconstructed 17th-century Jesuit mission that is one of the province's most significant heritage sites. The Wye Marsh Wildlife Centre, next door, offers canoeing and boardwalk trails through marshland habitat.
Penetanguishene, with its francophone heritage and Discovery Harbour historic site, is smaller and quieter. Boat tours to the Georgian Bay Islands depart from both towns in summer.
Orillia
Orillia sits between Lake Simcoe and Lake Couchiching at the county's eastern edge. It is Stephen Leacock's Mariposa, the small-town Ontario of literary imagination, though the modern town is a city of about 33,000 with a lively arts scene, waterfront parks, and Casino Rama on the nearby Rama First Nation. The downtown has good restaurants and an independent bookstore. The Orillia Opera House hosts theatre and music year round.
