P.S…Joshua Tree! November 16 – 19, 2025
Get ready for an unforgettable three-day gravel cycling adventure through the heart of Southern California’s desert landscapes!
Day 1: Joshua Tree’s West Side Wonders
Kick off your journey with a 60-mile ride into the mystical Joshua Tree National Park. You’ll cycle along paved and dirt roads, surrounded by the park’s iconic Joshua trees, as you make your way to the west entrance. Discover the hidden beauty of this amazing place before setting up camp at Jumbo Rocks. Prepare for a truly spectacular desert sunset, painting the granite formations in fiery hues.
Day 2: Across the Park
Today, we’ll pedal 35 miles across the park to our second camp night at Cottonwood. Enjoy the diverse scenery as we traverse this unique landscape. Experience the amazing light show of the Leonids meteor shower peaking that night!
Day 3: Desert to Dates & Palm Springs
Our final day takes us 65 miles out of the park via the east gate, across Interstate 10, and into the dramatic Box Canyon to Mecca. From there, we’ll skirt the vast Salton Sea and enjoy a sweet stop to sample dates at a local farm. Our grand finale is a cruise back up to Palm Springs, where we’ll check into our hotel to refresh before a fantastic celebratory dinner.
Support & Gear
While this is a challenging gravel cycling tour, you’ll have the luxury of a support vehicle to handle all the heavy lifting. You’ll still need your usual bikepacking gear, but leave the “big stuff” to us! We’ll provide the dinners, hydration and snacks. You’ll cover the breakfasts
Space is limited to just 10 riders, so secure your spot for this incredible desert escape!
