About Rock Dunder 

  • Rock Dunder is a treasure that lies within the UNESCO Thousand Islands Frontenac Arch Biosphere Reserve. Rising 275 feet above 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. For many, childhood memories of hiking trips to Rock Dunder remain fresh in their minds.
  • Rideau Waterway Land Trust members and supporters raised funds to purchase Rock Dunder in 2006. Scouts Canada decided to sell Rock Dunder, after using the site wilderness camp for almost 40 years, and to use the funds used to upgrade other camps  better suited to younger campers.
  • RWLT’s acquisition of Rock Dunder ensures this significant property remains undeveloped.
  • Open for hiking from sunrise to sunset, May 15 - Nov 15
  • $10 per group/car for a day pass, $50 per group/car for a season pass 
  • Purchase your pass ahead of time online here or at the gate when you arrive. 
  • *Note that passes available at the gate will be very limited during the peak hours of 10am-3pm (especially on weekends & holidays). To secure a spot, we advise purchasing your pass in advance online. 

Rock Dunder Location

  • Located at the portage leading to the Gananoque River system and down through the heart of the UN Biosphere, Rock Dunder provides a natural rest for canoeists traveling the Rideau Waterway.
  • Rideau Waterway Land Trust staff and volunteers have been making improvements to the trails at Rock Dunder. The two log cabins are off limits to hikers.
  • Rock Dunder is located just south of Morton.  Take Stanley Lash Lane west of Highway 15, and go 1200 metres to the parking lot and trail head.
  • Visitors need to be mindful of traffic when walking along the highway shoulder towards the Rock Dunder entrance off Stanley Lash Lane.


  • RWLT does not control arrival and departure times of visitors. A supporter pass does not guarantee a parking place. When on-site parking at Rock Dunder is full, visitors should use off-site parking to the north. There are No Parking areas signed on the shoulder of Highway 15 near Stanley Lash Lane. Cars parked illegally may ticketed or towed: the OPP enforces the No Parking areas.
