Start from the curbside parking on 13th St. in Yucaipa, CA. Three Hawks Trail is the second trail on your right - a 1-mile climb with a consistent, moderate grade. The lower half is fairly open with berms on many of the switchbacks. The top section kicks up a bit, and the switchbacks get tighter. There's a little bit of minor exposure in spots, but nothing too threatening. <br><br>The top of the trail dumps you off on Crafton Hills Ridge Trail for a more XC ride. Following the fire road to the Regional Park Trail, taking that down, and taking the road back to your car gets you around 10 miles of riding.
The start of the Thunderbird Trail is marked by this informative kiosk.
