6 Must-Ride Mountain Bike Trails in California
Updated: Sep 24
Stretching nearly 900 miles from its southern Mexican border along the Pacific to the Oregon border, California is a recreational playground offering outdoor enthusiasts a wide range of mountain bike trails. The state’s trail system has something for everyone, from scenic coastline trails to incredible routes that traverse California’s rugged mountains and lush valleys. To help you make the most out of your California mountain bike Adventure, we’ve highlighted six of the Golden State’s must-ride mountain bike trails for you to enjoy.
#1 Mt. Wilson Trail – Pasadena
The Mount Wilson Trail in Los Angeles is widely known as a gem for downhill mountain biking. Boasting a 5,000-foot vertical descent in less than eight miles, Mt. Wilson is the best ride in Southern California if you’re into enduro mountain biking.
To begin your Adventure, you’ll want to take the shuttle up to the top of this trail. The upper and middle sections are very narrow in spots and feature crazy switchbacks that will test your mountain bike skills. This trail’s totaling time is roughly 1.5 – 2.5 hours and will take you through various singletrack trails with stunning views and challenging terrain.
This is an advanced ride for bikers with strong handling skills. For riders looking to send this trail for the first time, Michal Kollbek is a professional mountain bike racer who frequently visits Mt. Wilson. You can see his guide profile on the Adventure IO app and book a guided ride down the mountain!
#2 Westridge Singletrack Loop – Santa Monica
One of Santa Monica’s most famous mountain bike rides, the Westridge Singletrack Loop is a great local ride that’s not too technical and functions as a great workout with Instagram-worthy views. The loop covers 11.6 miles and winds its way under shady sycamore trees and past running water as you begin your mountain bike ride with a short ascent up Sullivan Canyon. The main trail is a doubletrack, but there are singletrack routes that cross the wider path.
After making it through the loose rocks of Sullivan Fire Road and Mulholland Drive Fire Road, bikers make their way towards the scenic viewpoints near the Nike Missile Base Site. This is the perfect place to cool-down and refill your water bottles or use the restroom because next comes a local favorite, the Westridge Singletrack. With a max decline grade of 23 percent, this trail’s descent provides short, steep climbs from the Westridge / Mandeville Fire Road, followed by fast flowy descents.
Riders looking for a local pro to show them around Santa Monica’s fantastic mountain bike path can reach out to Adventure IO guide and professional mountain bike racer, Michal Kollbek, through our app and book a ride!

Located near the Camp Pendleton Marine Corps Base in San Clemente, the Hi’r Line and Dia loop is a multi-loop network of trails that start on Hi’r Line. This twisty, single-track trail mixes in berms and jumps for an exciting ride.
After crossing the creek, the loop turns into an easy cross-country trail that works perfectly as a warm-up or cool-down ride before heading down the Dia jump trail. Dia is incredibly fun as it features many alternate lines.
