This varied little traverse offers a nice landing and a good spot to hide from the rain. In fact, at one point during the El Nino summer a few years ago, it was the only piece of rock I could find in the Boulder area that wasn't either drenched or seeping.
El Patio is just uphill once you cross the downed tree over the creek to reach Bell Buttress. It sits on a comfy bench right of the big gully and directly below Arms Bazaar, Epiphany, etc.
This 45-foot long traverse is usually done right to left, though it goes both ways (V5). The crux is the middle, which can be made harder or easier depending on your elevation. A few eliminates can be fashioned as well. Beware the loose-looking blocks in the white rock above the traverse.
