The stunning Warsaw Caves, located near Peterborough and operated by Otonabee Conservation, were created by glacial activity over 10,000 years ago. Today, they offer some of the province’s best spelunking opportunities. Due to COVID-19, however, the caves and the cave trail remain closed. But all other trails – as well as camping and canoeing – are available. The Warsaw Caves Conservation Area has a number of downloadable resources – including maps for hiking and camping, plus detailed brochures for canoeing and spelunking. During Digital Doors Open, explore the caves and the cave trail through the video below.
