In reply to snoop6060:
> Both will be unbearable in the sun and probably just about climbable in the shade. Suirana is full of sharp crimps so I doubt my skin would last a weekend if the air temps are high which they will be. So just based on that I'd say chullila . It's only 3 or 4 hours between them tho isn't it? Just move if it's grim.
Siurana is fair bit further north and in the mountains (Siurana and Arboli are both at around 1000m). I've been a number of times in April (early and mid/late), max temps have usually been in high teens to low 20s. Often a bit hot for climbing in the sun but there's some really good shady options and conditions in the shade have often been excellent (and post crag beer drinking conditions in the sun are also good). Margalef (40 mins drive) also has some excellent shady cliffs. I'll be back to SIurana this April for a week from 18th.
Never been to Chuilla so can't compare it as late spring option.
