City of Rocks

The City of Rocks trail loop is made up the park's main Hydra Trail, with an extension to Table Mountain, taking hikers to one of the best viewpoints in southern New Mexico. The trail can be accessed at a few different points throughout the park. Beginning at the trailhead behind the Visitor Center and heading in a counterclockwise direction, the trail is a wide, flat, gravelly doubletrack circling the rock pinnacles in the shadow of a large mesa. Large granite markers can be found at intersections, although it is hard to get lost here.The turnoff to Table Mountain is at the mile point. Watch for a break in the fence to the right. The trail follows contours up the mesa, climbing twice, and ends at the southwest corner of the mountain. Although no trail on the top exists, it can be explored for some amazing views. The only way back down is via the trail. Reaching the bottom, Hydra Trail continues much as before, circling around the pinnacles before ending at the Botanical Garden just west of the Visitor Center.Hikeers interested in adding mileage can do so at various points. The park trail map shows an extension on the west side of the trails, and a loop can be made by taking the main access road south and then east to the observation point, circling back via Observation Point Connector. There are also a number of shorter trails that pass through the pinnacles, including the Planet Walk Trail, which features a number of astronomical displays.

The pinnacles making up City of Rocks were formed by a volcanic eruption millions of years ago. As the sediment eroded away, it left behind columns, some thirty to forty feet in height. There are few places like it in the American Southwest.
