This is a great trial to ride on right after work or those nice Saturday mornings. It has plenty of short burst climbs that reward you with wicked little descents through thick trees and creek beds. Very Fun!
How to get there:
Take Macarthur to the intersection of MacArthur and Hefner. Turn East (right) and follow Hefner behind the damn, to the first light. At the light, turn back North (left) and you will see Pat Murphy Park across the median, turn in at the first turn and park along the fence. The trailhead is opposite of the parking area, there is a large sign with a map and some beta, enjoy!
this trail dries pretty slow so you might want to look eslewhere after a rain.
