Following a burst of development back in October last year I have produced a guide to this new area of Segaria. There are over 30 routes here now most at the easier end of the grades and are ALL trad routes.
The Barranco Buttresses have a number of advantages over the main South Face (as described in the rockfax) that mean it could turn into a much more popular destination:
1) The approach is only about 15 - 20 minutes and primarily level.
2) The routes are much shorter, primarily single pitch.
So check out the guide:

Any feedback would be much appreciated.
