Rock Dunder School/Youth Group 2026

Welcome to Rock Dunder Nature Reserve Rock Dunder is a natural treasure that lies within the UNESCO Thousand Islands Frontenac Arch Biosphere Reserve. Rising 275 feet above Whitefish Lake's Morton Bay, Rock Dunder provides breathtaking views of the surrounding lakes and woodlands. Trails lead to one of the highest points of land in the area, and offer stunning vistas that are enjoyed seasonally by local residents and visitors to the area. It is an area that has captivated many generations of nature lovers, providing years of fond memories. Rideau Waterway Land Trust members and supporters raised funds to purchase Rock Dunder in 2006. RWLT’s acquisition of Rock Dunder ensures that this significant property remains undeveloped. Rock Dunder is open to the Public for hiking from sunrise to sunset, May 15 - Nov 15. Please be aware; school busses can not come up Stanley Lash Lane as there is no room to turn around. Passengers must be let off the bus at the bottom of Stanley Lash Lane, on the shoulder of Highway 15, and walk up to the gate house. There is no garbage disposal on site; please take home with you anything you bring to Rock Dunder, including refuse. We hope you enjoy your visit to Rock Dunder. Please dress for hiking on rough trails including appropriate footwear. Rock Dunder consists of uneven terrain. You are assuming liability for all risks associated with using the property by purchasing this pass.
