Yup, and also rough on the hands! As Crillz suggested, bring tape for the hand cracks.
The face climbing is amazing, but will wear through your finger tips in 4-5 days of steady cranking. If you can, build up some calluses before you go down. And if not, be ready to take a rest day or two when they get tender (you'll know). If they tear, you'll be more limited. Have fun - it's a unique place.
