The beach can be accessed here but be wary of the tides as they move at one inch per minute here. Don't travel along the shore here. You can get caught up against the cliffs with the tide.
Once you enter the woods at the top of Christie fields, this trail starts, but is not called this by any signs. There is a good climb and descent on this trail with a few good viewpoints and stairs as well. It connects the Christie Viewpoint Trail to the Mill Brook Canyon Trail for those looking to extend their hike.
