 First, the trail itself climbs rather steeply from the road, along the sometimes steep and rocky slopes alongside the creek.Second, the trail is served by two parking lots along 23A, both of which require a walk of at least 0.2 mile (400 m) to reach the trailhead at Bastion Falls, just above 23A at a bend in the road.Due to both the rugged surrounding terrain and the limitations placed on Forest Preserve land by the state constitution, New York's Department of Transportation (DOT) has been unable to expand the narrow shoulder on either side of the road, requiring that visitors walk very close to high-speed traffic, including trucks, some of which are in the middle of descending a pronounced grade.
