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.
Born in fire over a billion years ago deep in the roots of an ancient mountain range, Rock Dunder is part of a large igneous feature termed the Lyndhurst granite. Wind, water, and the ice of retreating glacial ice sheets sculpted this hard pink granite into its present shape.
Rock Dunder offers three different trail loops:
The Cabin Trail: easy, 1.3 km walk, beaver pond, mixed forest and a white pine plantation. Hiking boots not required.
The Morton Bay Loop: 2 km, two moderately steep sections to and from a small peninsular
outlook over Morton Bay, mixed forest. Hiking boots recommended
The Summit Loop: 3.9km, runs alongside Dean’s Island through a variety of forest, sneak peaks over rocky cliffs, panoramic view of the Rideau Waterway at summit. Hiking boots recommended
