Please note: Our ultimate desire is to preserve and protect this natural treasure alongside giving enjoyment and ensuring people's saftey. We assess regularly the rock formation (by Engineer) as climate change and time (frost/thaw, tree growth etc) may have an impact on the cave stability. As a consequence we may need to limit cave visits as we feel necessary and reserve the right to close at any time if needed.   We sincerely hope you understand and appreciate our efforts. Angela Argmann and family  (owner and caretaker since 1975).

Cave History: The Mindemoya cave was carved out after the last Glacier 10,000 years ago and is on private property. It is approximately 9 to 15 ft high and 80 ft deep. At the very back of the cave is an opening to the surface from there the crevice route goes all the way to lake Kagawong which is at a higher elevation. Thus, the crevasses created during the Glaciation “ice-Age” and the immense water power after ice melt was the “Creator” of the cave. In 1888, the cave was discovered by three Mennonite preachers while out fishing. Seven skeletons were found and were thought to belong to the Odawa. The skeletons were taken to a Toronto museum, that was later gutted by fire. In 1986 to gain access to the cave an Inco engineer and his workers cleared away 6 ft of dirt and heavy fallen rocks to open the entrance and clear the floor. Prior to this work, the owners obtained permission following a soil assessment by a regional Archaeologist from the Ministry, that indicated no signs of habitation or human remains. The cave is gated to preserve and protect the beautiful natural carved Dolomite rock walls and the smooth washed out limestone floor. Watch your step on the trail and please no climbing or defacing of the rocks. Enjoy!
