The climbing is great, the place is quiet (sleepy even), the grading used to have a reputation for being nails but has been brought into alignment with elsewhere now (anomalies exist still). It's very pretty.
The bolting is good and there are many newer areas requiring a short drive but the main gorge is walking from town (and goes of for miles). There is a newer guidebook.
There are "hot" springs for swimming (20C) all year.
IIRC the refugio is often closed and a bit pricey for staying in. I didn't know there was a campsite, I've always stayed in a rental apartment when I've gone.
90% of visitors are day trippers for the spa water - it's very quiet.
You can rent mountain bikes in town and there are good trails around.
