Located southwest of Phoenix, the rugged 19,800 acre Estrella Mountain Regional Park has a network of trails ranging from 5 to 30 miles through spectacular mountain scenery. The infrequently traveled trails are refreshing compared to the crowds at South Mountain Park.
To reach the Estrella Mountain Regional Park mountain biking trailhead from Phoenix, head west on US10 to the Estrella Parkway exit (#126). Turn left heading south on Estrella Parkway. After about 5 miles, turn left on Vineyard Avenue for 0.4 miles and then turn right on Casey Abbott Drive into the park. Follow signs to horse corral trailhead.
In addition to the main trail network, there is a Competitive Track located just east of the main park with a trailhead near the Phoenix International Raceway at the very south end of El Mirage Road.
Overall, Estrella Mountain Regional Park is the 7th most popular mountain bike trail of all 103 mountain biking rides in Arizona.
