Activities on the lake

There are plenty of activities to enjoy on Three Mile Lake. Boat lovers can easily access the lake through the public boat launch on Shea Road, located on the south side. However, the lake’s shallow and narrow depths make it best suited for boats up to 20 feet long. For fishing enthusiasts, Hammell’s Bay is the ideal spot as it is the deepest part of the lake and home to a healthy population of smallmouth bass, largemouth bass, and walleye.

For those looking for more adventurous water sports, wakeboarding and wave surfing are popular activities on the lake. Personal watercraft like Wave Runners and JetSkis are also allowed. If swimming is more your style, the lake’s bays and inlets offer excellent conditions for a refreshing dip. Echo Beach, located on the eastern side of Hammell’s Bay, features a hard-packed sandy shore, perfect for sunbathing or playing beach volleyball. So grab your gear and enjoy all that Three Mile Lake has to offer!

Exploring the area

If you’re looking for a break from the lake, there are some fantastic golf courses just a short drive away, including Windermere Golf & Country Club and Diamond in the Ruff Golf Club. If you’re willing to venture a bit further, there are more courses in Port Carling and around Lake Joseph. While you’re in Port Carling, a charming town in Muskoka, why not make the most of your time?
