There's a newly built parking lot located next to the Port Authority check point. From the parking lot it's a short, but decently steep hike up to the dinosaur tracks. The trail is well-defined and has markers along the way. When I visited most of the dinosaur tracks were outlined with little pebbles to make them easier to see. It can be challenging to distinguish the tracks from natural grooves in the rock, but if you look carefully you can see a number of 185-million year old tracks made by a Grallator.
