Butterfly Lake Boat Ramp provides water access to Butterfly Lake, a small, quiet lake of roughly 65 hectares in the Township of Muskoka Lakes, near the village of Glen Orchard at the junction of Muskoka Roads 118 W and 169.

The lake is well suited to boating, swimming, and watersports, with a maximum depth of 6 metres and good clarity. Anglers launching here can target northern pike, smallmouth bass, largemouth bass, and yellow perch.

The lake's compact size and numerous small inlets also make it a popular destination for canoe and kayak exploration. Butterfly Lake Resort, situated on the shoreline, maintains a private boat launch alongside the lake's recreational amenities.
