Level 4 Required – 4WD High Clearance**
We'll meet at 9:00 am at the south entrance to Canyon Sin Nombre, off the S2, 34 miles south of SR78 (Scissors Crossing), about 0.6 miles south of Sweeney Pass. We'll brief and air down before starting our journey within ABDSP. We'll travel 13 miles on Canyon Sin Nombre to Vallecito Creek Road, then to Arroyo Seco del Diablo, reaching the Diablo drop-off, which has both easy and challenging descents. From there, we’ll head north to Split Mountain Road, where our trip ends. Expect rocky roads, washboard, soft sand, and mild challenges. Lunch is BYO, and a stop will be made. Check the weather and dress accordingly. Bring water and a full tank of gas. GMRS channel 15 is optional. 4WD is required; no AWD. This is a members-priority trip. Visit the Nature Center or call to reserve: 760-767-3098.
