The campsite notice board is good. Or you'll always find climbers hanging out in the cafe in the Adventure Centre. People used to hang out and shoot the shit in Climb On, but I'm not sure how much that happens any more after they moved in with another outdoor retailer. The Zephyr is another option, but you're less likely to find people looking to climb, and more likely to hear about the lastest yoga position for your dog, or how great wheatgrass enemas are or something. Campsite or adventure centre would be your best bet when you get there I'd say.
