Get stoked for mountain biking in southern California right in the nearby San Bernardino Mountains!! (and lots of other places close by)!

There are many trails for beginners and those who want to learn and there are also a multitude of world class downhill trails that the experienced rider will find exciting and challenging (some just a 20 minute drive from campus, or a ~45 min pedal!). Mountain biking in southern California is all about steep climbs (some with fun techy stuff!) that lead to epic downhills. However, there are many mellower trails that everyone can enjoy a nice cruise on and many have techy offshoots (drops, jumps, chutes, etc.) that keep things interesting. Who doesn't think riding on two wheels is one of the best ways to spend time in the great outdoors?

The mountain biking community in the Pasadena area is welcoming and stoked! There are always lots of riders out on the trails and the local bike shops are staffed with super friendly cyclists happy to share tips and are love Caltech students (discounts!). There are lots of opportunities for trail maintenance days and volunteer opportunities through the Mt. Wilson Bike Association (MWBA, https://mwba.org/) that make it easy to meet other cyclists and give back to the mountain biking community. The MWBA also has lots of meetups for rides, socials, and shenanigans throughout the year (when not in COVID-19).

Need more trail ideas? Try out MTB Project and TrailForks apps or email ascott@caltech.edu.

Group rides will be organized after COVID restrictions are lifted.
