Hikers can continue west on to Little Cove. The 13 km trail wanders close to the cliff's edge, darting in and out of the emerald-colored forest. Heading in the opposite direction, east of the Marr Lake Trail, leads to the Grotto. Hands and knees scrambling straight up over huge chunks of weathered dolomite lead back up the escarpment. The grotto, a popular swimming hole in the summer, lays in the mouth an enormous cave at the bottom of the cliffs.
Aquamarine water is lit from below, creating a gentle glow that illuminates moss dripping walls.
Further along the trail, a spectacular arch carved out by the rough waters has formed another swimming hole perfect for cooling off. A second pristine rock beach, framed by the limestone cliffs, creates the illusion of a Caribbean beach from high up. I clambered down the escarpment hoping to cool off my feet, but near freezing water temperatures soon dispelled the myth of tropical waters.
