Located just 90 minutes from Algonquin park and 80 minutes from Ottawa, in the town of Eganville Ontario, lies the Bonnechere Caves.

Under a hill of limestone, said by geologists to have been the bottom of a tropical sea 500 million years ago, the Caves present a weird and wonderful sight. Stalactites, or rock icicles formed at the rate of one cubic inch in 150 years, hang from the ceiling and the handiwork of nature is enhanced by electric lights. Entombed in the rock and preserved forever can be seen fossils of coral and sea creatures alive long before the age of the Dinosaurs. Millions of years in the making, the Bonnechere Caves are a thrill for the sightseer.

What To Expect

Guided tours leave every twenty minutes and last approximately forty five minutes to one hour.

On the hottest summer days, the Caves are cool. For your comfort, take a light sweater. There is a set of stairs leading you into the Caves and one that takes you out of the Caves. A beautiful trail that passes an old mill and sink hole will bring you back. Low-heeled shoes are recommended.

For pictures underground, don't forget your flash attachment. The white waters of the waterfall are a fine subject for movie fans and artists.

Picnic tables are provided for the use of visitors. Soft Drinks, ice cream, snacks, souvenirs and science type products are available. Due to the environmental sensitivity of our site, we have upgraded outhouses and hand pump to wash your hands.
