Crawford Lake keeps its secrets in its sediment. We’ll share some of them with you on this adventure.
This emerald green meromictic lake is a scientific marvel. It’s so still that its deep layers never mix, and nothing that settles to the bottom ever gets disturbed. That untouched geological record, laid down year by year, is part of why it’s so special. We’ll follow the lake’s shores on the newly completed boardwalk, with radiant fall colours towering above us.
From the lake, the trail climbs onto the Niagara Escarpment and joins the Bruce Trail, the longest trail network in Ontario. This section has some moderately technical terrain that will ask you to slow down and pay attention.
Partway through, the trail passes the reconstructed 15th century Iroquoian village, three longhouses rebuilt on their original footprint.
From there, the trail carries on toward Rattlesnake Point, climbing to a pretty spectacular viewpoint over the canyon before looping back through mixed hardwood forest to the lake. By the time you're back at the boardwalk, you'll have covered the escarpment's best angles: canyon, cliff, and calm water, all in one loop.

Rattlesnake Point Viewpoint: The high point of the loop, with open views out over the escarpment cliffs and the valley below.
Crawford Lake: Formed roughly 10,000 years ago in a sinkhole carved out by retreating glaciers, tucked into forest at the top of the escarpment.
Peak Fall Colours: The escarpment forest turns early and hard here, with the ridgeline views making the reds and golds even more dramatic than from the trail floor.
