Lake on the Mountain Provincial Park is located in Prince Edward County along the shore of Lake Ontario. It is a relatively small park and there are limited facilities and activities. The park has a sign that explains how Lake on the Mountain was formed and provides sweeping views of Lake Ontario on one side and Lake on the Mountain on the other side.
We spent the day hiking at Sandbanks Provincial Park and decided to make a detour at Lake on the Mountain since it’s only a 25 minute drive out of the way. There are no hiking trails in the park, so we figured this would be a quick detour. Besides, we needed to make more progress on our Ontario Parks Challenge.
We pulled into the parking lot and checked out the sign that provides more information about how Lake on the Mountain came to be.
Beneath Prince Edward Country is hard limestone. Over 12,000 years ago this area was once covered by a huge glacial lake known as Lake Iroquois. Lake on the Mountain and the nearby Roblin Lake and Fish Lake are three deep gouges within the surface of that large limestone table. When the glaciers retreated, Lake Iroquois drained into the St. Lawrence River until only the much smaller Lake Ontario remained. High on the County’s tableland, deep holes retained to leave these three lakes, which are elevated remnants of former Lake Iroquois.
Lake on the Mountain is the largest and deepest of these ancient lakes and is believed to be 33m deep. Each lake was probably the site of small pockets of softer limestone that slowly dissolved into a sinkhole. The narrow ridge that separates the lake from the cliff overlooking Lake Ontario makes this the most scenic of the three lakes.
The park provides sweeping views overlooking Lake Ontario from on top of the cliff.
We then crossed the road to view Lake on the Mountain, which is situated 60m above Lake Ontario. There’s a wooden viewing platform here, but there was a sign and tape around it to indicate that it’s been closed off. That didn’t matter too much as we could clearly see the lake right from the shoreline.
Overall we spent around 10 to 15 minutes at Lake on the Mountain. By the time we wrapped up it was nearly 5p.m and we were getting hungry. From here it’s about an hour and a half drive to the cabin.
