The Cinder Lake Boat Ramp is a backcountry access point located off the Cinder Lake access road, which branches from Black River Road in the Algonquin Highlands region of Ontario.

It serves as one of two public entry points for canoeists and campers heading into the surrounding backcountry. The access road leading to the ramp is remote and unmaintained, traveled at the user's own risk.

Reaching the launch requires navigating rough terrain and two water crossings, making it suitable only for trucks, SUVs, ATVs, or snowmobiles in winter — 4-wheel drive capability is strongly recommended.

The site is not accessible to standard passenger vehicles.
