|1|| No Name
The left most route has no name but many people call it La Comadreja Enchilada and at the time of writing the only route with seemingly bombproof protection, is also the hardest at Rio Oro. Start to the left of the thin crack with a good three finger pocket and a home made first bolt. Make finger strength and clean footwork dependant moves up and to the right to the commercial bolt for a feeling of security, and clip while pinching with the left. With a slight overhang, from here work your way through the crux, using the thin crack for a couple of moves before climbing back towards the left and finishing on a high step with great pockets before the anchors. As with most routes on the wall, dirt and overgrowth can be a problem, especially near the rounded top of the climb.
|2|| La Virgen
Directly to the right of 'David Ulloa' and just to the right of the thin crack is the delicate and resolute La Virgen. Climb up the crack using the odd face hold clipping the homemade bolts along the way. Past the third and final bolt climb up and to the left using large pockets and slopers until you reach the same anchors as 'David Ulloa'. This route has yet to see a successful headpoint.
|3|| El Pedo Loco
For this climb follow the kinked pen mark crack directly to the left of the easily identifiable Media Luna. At the time of writing this route does not have any top anchors and is missing a first bolt, and therefore the best thing to do is to set up a top rope on one of the trees at the top of the wall. Climb directly up the face using some well placed feet to ensure a successful attempt for the top.
|4|| La Media Luna
Media Luna is the most apparent climb on the wall as it follows the obvious crack that is just to the left of the strangler fig tree roots. This is also the route that you will rappel in from when entering Rio Oro. Start with an easy step up onto a ledge before using a mix of layback and juggy crack moves to make your ascent. The homemade anchors at the top of this climb are a little sketchy, I would recommend creating a top rope from a tree, or if leading, topping out and then down climbing the roots. This climb can also be completed as a trad route.
