This is an epic gravel tour through the northern Sierras. It has a little bit of everything: big climbs along the Sierra range, cruises across bucolic valleys, and even a ride over a massive volcano (Mt Lassen National Park). The distances between resupplies are, thankfully, very reasonable.
The route is roughly: 60% gravel, 35% pavement, and 5% singletrack. Given that you’ll be riding a loaded bike through some sections that have chunky gravel and rocks, using tires that have some tread and are at least 45mm wide is a wise choice.
GPX Tracks & Waypoints
Due to the above-average snowfall this winter, the 2023 route will not go over the top of Mt Lassen. Instead, we’ll do a “topless” alternative and loop around the lower reaches of the mountain. The mileage and elevation gain, however, is pretty much the same as the 2022 route.
