Halle Ravine is a small but unbelievably beautiful preserve in Pound Ridge, part of the Pound Ridge Land Conservancy collection of hiking places. Even a panorama camera like the Sony Cybershot can't capture the deep undulations of its steep gorge, and the height of its first-growth hemlock forest. The trails are well-marked and maintained. We love it.
On a Sunday morning, we met two other parties; both had fellow dogs. Both had dogs who roamed with impunity. It likes.
You can pick up a map from the kiosk at the head of the trail.
You can do this hike easily in an hour or so; it leaves the road and ducks into the woods, past one still, green pond and another clearer pond before a dam. The trail then follows the edge of a stream, as little foot bridges criss-cross the water at its low points. Near the far end of the trail, you'll climb steeply to a little cul-de-sac on a hill before coming back down and retracing your steps to the beginning. There are benches along the way.
The Halle Ravine entrance is on Trinity Pass just south of Donbrook Road at a white gate set in a bordering stone wall.
