The Seismosaurus Trail is about a mile long and relatively flat. It leads up to a small cave with petroglyphs, where the trail terminates. Sometimes the trail is tricky to follow, so have the appropriate navigation ready. Parking can be found at Ojito Wilderness Parking on Cabezon Road. This trail was named after the Seismosaurus dinosaur uncovered here, one of the largest ever dug up in 1985.
