No wave higher than head in Busan I believe, but a few surfers are recently being seen in Songjung beach next to Haeundae. Quite Not like in L.A I suppose, just for foretasting something like that I don't know...
Yeah, Guseo(구서동) area would be a bit better in terms of noisy, touristy, climbing accessibility. Good luck!!!
Climbing = alive = happiness
