Just to the right of Piolin, and ending with the same anchors, is Diedro. Start by standing on the protruding ramp that moves up to the right towards Ron. Use the two low pockets to position yourself before traversing right onto a crimp and geston. Use some burly strength to get to the pocket just above and then clip the second bolt on the extremely deep monster pocket. From here traverse to the left using a sloper and a couple of wide stances with decent ledges before getting to the anchors shared with Piolin. In the final push for the anchors Diedro uses some of the same holds as Piolin, but to maintian the 5.10c difficulty try to stay as far to the right as possible.

Ethic: inherited from El Coliseo
Respect the land owners.
They are kind enough to let you use their property for your enjoyment.
Respect other climbers.
Climbing is a community sport where the only opponent is the cruel crux that sends you airborne.
Respect the environment.
Above all, respect the environment. The plants, the earth and the rock itself were here long before you came into existence and will continue to exist long after you are gone. Sustain its survival by treating it properly.
  • Pick up trash, even if it is not your own. Take at least one piece out on every trip.

  • Do not kill flora or fauna, no matter how small or large.

  • Live and climb as though you are organic with your environment.
