> Just how much of a big boy do you need to be to make a trip to Oliana worthwhile? are we talking 8c monsters only or is there good low 8's?
Very big, I'd say. Apart from the handful of sevens mentioned previously, there's one 8a, one 8a+, then a big jump up to 8b+ or harder.
All in all it's probably best to give Oliana a bit more time before folks start visiting; the cliff is still festooned with ropes hanging down unfinished projects, and the rock, even on some of the existing routes is still (apparently) a little crumbly.
There seems little doubt that Oliana will eventually become a major destination on the Catalunya sport-climbing tour, but for all but the very best there are far better alternatives in the area — Terradets, Tres Ponts, Siurana, Montsant — to name just a few.
