Alta is a South Mountain technical gem. It is a favorite for hikers and one of the legendary technical trails for mountain bikers. At 4.5 miles coast to coast Alta gives you a gorgeous sufferable climb for 1.5 miles — followed by a mile of challenging exposed descending. Then climb for another half mile plus and you are at the saddle — ready to descend into Alta tech oblivion.

If the tech up to this point didn’t buck you right off your bike, there are a few moves down this section that surely will. Switchbacks, exposure, loose, tight, cactus, and did I say steep?

Do not attempt Alta unless you are a seasoned skilled rider that is bored with National, Corona Loma, Holbert and Kiwanis. The “easier” climb is East to West, the gnarly of all gnarly climbs is the opposite. Make sure you have your SPOT messenger if you ride solo. Better yet, bring a buddy that is strong enough to carry you down the mountain when you endo. Not many bikers or hikers will be out there to rescue you.

The trailhead is just a short road stint from the parking at the San Juan Junction. Enjoy. Be safe. Good Luck!
