Muskoka Waterfront Cottage on Three Mile Lake

Escape to this peaceful Muskoka retreat on Three Mile Lake. Enjoy your private sandy beach, calm swimmable water, and 3 bedroom cottage stocked with all the essentials.

Step outside and enjoy stunning lake views from the deck, grill dinner on the BBQ, gather around the outdoor fire pit, or unwind on the private dock. Spend your days pedal boating, paddle boarding, swimming, or ice fishing in the winter.

1. Three Mile Lake:
Our cottage sits directly on the beautiful shores of Three Mile Lake. While the lake is a wonderful spot to relax and take in the views, please note that blue-green algae blooms can occur in late summer, particularly after August 10th. This doesn’t happen every year, but when it does, swimming may not be possible.

Because water conditions are out of our control, we kindly recommend considering this if swimming is an important part of your stay—especially if booking later in August. We want you to have the best experience possible!

2. Watercrafts:
You`re welcome to bring your own watercraft. The dock is equipped with tie-offs for secure mooring during your stay.

3. Water Depth:
Three Mile Lake is shallow at the shoreline—only 3.5 to 4 ft deep at the dock. The lake’s median depth is 11 ft, with a maximum of 36 ft. For safety, diving is strictly prohibited at all times.

4. A/C:
The living room features air conditioning controlled by remote, and each bedroom is equipped with its own ceiling fan.

5. Drinking water:
The cottage has a drilled well and a UV filtration system—tap water is safe and drinkable.

6. Pets:
You are welcome to bring a pet along. A pet fee is applicable.
Please note: guests must clean up after pets, be responsible for any pet-related damage, and assume responsibility for pets to not enter the lake if a blue-green algae bloom occurs.

7. Power Outages:
Power outages can occasionally occur in Muskoka. Please note that this property does not have a backup generator. During an outage, electricity and water will be unavailable as the cottage operates on a well system.
