Is it easy to show up and find a climbing partner there? Where do I go?
I'm coming from USA, 28, and am experienced in sport single pitch. I've sent 6c (5.11b), but I've been climbing less and have less endurance. On this trip, I'd lead 6b (5.10d) but am certainly willing to work harder routes with you... I won't be able to contribute much after 7b (5.12b) though.
Yes it's easy to find climbers in Yangshuo. I went there solo in late August and didn't have any trouble finding people to climb with. Do stay at Climber's Inn, that's the #1 hostel that climbers normally choose. Yangshuo is awesome, and probably my favourite climbing area to date. The whole area is very accessible and most of the crags are within 10min reach on a scooter. Have fun!
