Lake Rosseau

Beautiful Lake Rosseau in the early morning light.


Two hundred kilometres north of Toronto, Lake Rosseau is known to be one of the most prestigious lakes in Ontario. As one of the Big Three, Lake Roseau – along with Lake Muskoka and Lake Joseph – is part of a series of regionally connected lakes. And as such, Lake Rosseau provides access to 500+ kilometres of shoreline to enjoy and explore.

Activities on Lake Rosseau

As a massive lake with several bays and islands, Lake Rosseau is great for all water sports and activities. Sailing, water skiing, wakeboarding, canoeing, swimming and fishing are excellent ways to spend a day on the water.

There’s even an Ice Bar, where guests are served tapas in a -15° setting while they experience signature flights of Crystal Head Vodka. I can already taste it.

Exploring the area

Food and drink are only some of what Lake Rosseau has to offer. The village of Rosseau is a charming little hamlet on the north side of Lake Rosseau. The legendary Rosseau General Store, filled with old-world charm and the Rosseau Ball Diamond and Field house features a multi-purpose play area for various activities. And you can’t miss Rosseau Waterfront Park, a landscaped park with a sandy beach, a large playground, picnic facilities, a boat launch, public washrooms and change rooms equipped with showers.

At Lake Rosseau’s south shore, you’ll find Port Carling, the hub of the three Muskoka lakes. Port Carling is known for its friendly local businesses and beautiful shops. Stop in for a quick lunch at the dock overlooking the lake at Turtle Jack’s, cruise the lakes in an antique wooden boat, or explore the local heritage at the Muskoka Lakes Museum.

Whether you prefer to lounge at the lakeside swimming in the sun, spend your days touring the lakes on the boat, discover the sights and sounds on the numerous trails, or explore the local attractions of nearby communities, sought-after Lake Rosseau offers it all!
