I've glanced through Elanthipedia and it doesn't say specifically- Is there climbing in the 230+ range on Hara? It says the island has swimming up quite a ways, but I'd like to be able to continue training both if I head out there. With swim and climb 215 and 230 respectively, will I have issues?

At 230 you may not be able to actually climb it, but you can probably learn a bit "practicing" until you can make it all the way.
