Welcome to my Ontario Caves website. I have created this website to show my fellow cavers and the internet curious the splendid tunnels, passageways and cave formations that lay hidden under our feet.
Caving is a hobby of mine that has developed over the years, half the fun is the hunting, searching and conversing with landowners that is required to find and discover the hidden cave passages. Many caves are located on private property and this is one reason that cave locations are generally not given out, it is up to the land owners who are generous enough to let us on their land if the location is kept secret and if pictures can be posted.
One purpose of this site is to provide information to people who have a desire to learn more about caves, a database of clubs and cave related links for people to explore.
I have divided Ontario up into three graphical regions to keep track of the caves. No sensitive cave locations or locations of caves on private property are listed on this site, this is for the protection of the caves as well as the privacy of the land owners who are generous enough to let us enjoy our hobby and explore the underground world.
I am always looking for new caves, sinkholes and sinking streams to investigate and to explore, please feel free to contact me if you have an area or spot that you think would be of interest to me. You can reach me at the following email link.

(attention) All caves and mines are very dangerous and should not be entered at any time. This site is for educational purposes only, explore at your own risk.


Thanks to all the other cavers and property owners who have provided information and or access to Ontarios finest hidden caves.
(All sensitive cave locations are kept secret at the request of the landowners)

Mystery shaft in the middle of nowhere. Myself, Mick and GW recently explored this 16.5 foot deep shaft in Southwestern Ontario. Various large sinkholes and loads of bedrock elevation hint at the possibility of large caves beneath our feet. Unfortunately the shaft is choked with debris, a possible dig for a future date.

This picture was sent to me by Marc-Andre Dorval of Speleo Club Nibelungen. The club is in the process of digging this sump in Lafleche Cave in Quebec Canada. Currently they have removed debris to three meters below the water level with the hopes of finding virgin passage. The divers name is Donald. Glad to see I am not the only person crazy enough to spend the weekend digging for virgin tunnel.

First time cavers

If your looking to explore your first Ontario cave, then look no further than one of the many tourist cave's open for public tour's. Its great if your a first time caver, or if your just looking to get the family out for the afternoon. Bonnechere Caves in Eganville Ontario provides nice solution formed passages, and in a controlled atmosphere safe for the whole family. Scenic Caves in Collingwood Ontario is another spot good for adventurous people of every age. Please view the following link for a list of commercial caves in Ontario. Commercial Caves Of Ontario.

If your looking for caves in their more natural state, then look no further than the Toronto Caving Club. They offer numerous beginners trips thru out the year to some small caves along the Niagara Escarpment. Its a good way to get your feet wet, and meet some good people. You will also make connections in the caving community, and gain the trust of your fellow cavers.
