 Awesome combo of trails. Lots of exposed steep and technical stuff up top, gets faster and more flowy from merrill to sunset. El prieto is nice shaded canyon ride that has some fun quirky sections.
2 small climbs link merrill to sunset and sunset to el prieto

      after riding through the tunnel there is a big landslide. You will have to dismount to cross it. As the temps warm up more rocks could come down.
