In reply to Lesdavmor:
We've been several times over the last 20 years, most recently a few months ago. It's a great place, lots to do at all grades, in and out of the main gorge. There is a fairly recent guidebook in which the grades have been updated so they are less old-school (though still not giveaways).
The refugio always seems to be shut when we go - maybe we just pick the wrong time of year - but there is a climber friendly bar/pizzeria in the Plaza Espana in the town.
Van camping is formally tolerated in a parking area under the main bridge.
It can be combined with a trip to Chulilla - the new development there is amazing, especially if you are operating at 7a and above.
