Tyendinaga Cavern & Caves

Tyendinaga Cavern & Caves Welcome to Ontario's largest natural cavern! Join us for a family-friendly underground adventure! The tour takes 45 minutes to complete.

We are a family owned and operated business just outside of Belleville, Ontario. For the past 15 years we have been offering guided tours of Ontario's largest natural cavern. Our tours are designed to be very family-friendly, with a little something for all ages. This is a beginner level tour, so no spelunking skills are required! We also offer a scenic lookout point and a sheltered picnic area, so feel free to pack a lunch and enjoy. On average, most visitors spend about 1.5-2 hours, so there's plenty of time to check out surrounding attractions in the beautiful Bay of Quinte area. Entry prices range from $5 - $15/ person. Our 2023 season will begin on the Victoria Day long weekend in May. Check this page in the coming weeks for updated hours and scheduling. Reservations will be available through our website as of April 1st. We look forward to welcoming you to Tyendinaga Cavern & Caves!
