Glassford Summit Trail is a 4.2-mile moderately difficult hiking trail that showcases the remains of an extinct Miocene-era volcano. The trail was dedicated in May of 2016 and is accessible from a parking lot at Castle Drive, which offers public restrooms at the trailhead. The first mile of the trail is a fairly moderate hike through desert grasslands and provides interpretive signs that offer information on the area’s wildlife and geology. After the first mile, the trail ascends to a peak elevation of 6,123 feet, with picnic tables offered at each quarter mile for visitors to take breaks and enjoy the scenery. At the trail’s peak, visitors can descend into the volcano’s extinct inferno and observe its crumbling lava flows, which were highly active between 14 and 10 million years ago. 360-degree views of the surrounding mountain valley are offered, with nearby Prescott National Forest, Flagstaff, and Williams visible on clear days.
