Decent limestone with an amazing view of the Mediterranean. Not really a reason to go all the way to Spain in itself, but while your there, it's a great spot to get to. Only about a half hour drive from Barcelona, and maybe half that from the airport.
It faces south so it's usually too warm in the summer, but it does dry quick after rain, nice place when its cool out.
All sport, pretty well equipped. Most climbs are 5's and 6's, and there's not much harder than 7a. Some of the easier climbs can be a bit polished.
Via car: Drive south from Barcelona on C31/C32, pass the airport, keep right on the C31 (avoiding the toll road tunnels signed for Tarragona). Stay right (signs for C31 to Sitges) until you get to a round about, it'll be the first right ( head away from the coast) pass signs for the Parc de Garraf
go straight through another roundabout, and drive up the steep switchbacks. Few minutes drive brings you to the well visible crag on the right with parking on the left. There's an obvious scree trail (usually with cairns) up to the cliff. Maybe 5 minutes, but pretty steep uphill.
