Local Mountain Biking Trails
Southern California is an excellent place to mountain bike! The San Gabriels have numnerous trails close to Caltech, most, unfortunately are very technical and learning to bike can be a challenge. I've give them 1-3 stars for quality and a number 1-3 for how technically difficult they are!
Windsor Ave/East JPL parking lot
- El Prieto (7.8 miles; 1,243 ft gain; Quality 3, Technical 3)
Singletrack with numerous switchbacks and stream crossings.
- Brown Mountain
- Flint Canyon Trail
- Monrovia Canyon Road (11.67 miles; 2,154 ft gain; Quality 3, Technical 1)
Mostly paved road. Unpaved trails are in excellent condition. Best in fall and winter time, but summer and spring early mornings are pleasant too.
