Three Mile Lake

Tranquil Three Mile Lake Muskoka Lakes.


Three Mile Lake (Muskoka Lakes) is nestled between Rosseau, 24 kilometres to the north, and Port Carling, 20 kilometres to the south. It has a surface area of 8.7 square kilometres and a shoreline perimeter of over 31 kilometres. The lake’s unique shape and its rugged beauty keep visitors returning year after year.

Activities on the lake

Activities on Three Mile Lake are relatively easy to come by. The lake allows motorized vehicles for boat lovers, and the public boat launch on Shea Road on the south side of the lake offers easy access. However, Three Mile Lake is best suited for boats up to 20 feet long due to its shallow and narrow depths. So launch your boat, and head out to Hammell’s Bay. As the deepest part of the lake, you should have no trouble catching a bite here. A healthy fish population of smallmouth bass, largemouth bass, and, most notably, walleye live within the lake’s depths.

For those adventurous water sports enthusiasts, wakeboarding and wave surfing are popular activities on the lake, as are personal watercraft like Wave Runners and JetSkis. Or, if a simple swim is more your style, this lake’s many bays and inlets offer splendid conditions for a dip. For example, if you head over to Echo Beach, on the eastern side of Hammell’s Bay, you’ll find this entire area is a hard-packed sandy shore. So grab your beach blanket or set up a volleyball net and have at it.

Exploring the area

If you want to get away from the lake for a while, you’ll discover a series of exceptional golf courses only a short drive away, such as Windermere Golf & Country Club and Diamond in the Ruff Golf Club. And if you want to venture even farther out, there are several more courses in Port Carling and around Lake Joseph. And while you’re in the picturesque town of Port Carling, why not take advantage of the best that Muskoka has to offer? You’ll discover a cornucopia of restaurants and shops to explore. Whether items you need for the cottage or trendy gifts for family and friends at home, you will find them there.
