Sorry it's a late reply! If you get off at the beach, keep walking past the rocky island (accesible by land during low tide). . . if you walk out by the island, you can see the cliffs, but the best way to access them is to head back to the road until you're across from a dirt parking lot and see an access trail heading steep and up. Follow the train past some army trenches and you'll see the downclimb access. Hope you find/found it. . . really a wonderful place!!
