Longboards are a pain to travel with, good for the pass but you'd probably wanna surf elsewhere...there wasn't much swell when I went, but I scored some fun waves South of Byron. Waves are easy to find coz the roads are close to the beach, not like the SW where it can turn onshore coz you've stuffed around looking too long. If the swells big though you might be able to pick a section between the gazzilions of people along the Pass stretch of coast. Dunno what the other places would be like, they're more open to the swell than the pass area, so maybe not the the go if the kids are groms.....next time I go, I'll stay in Ballina or maybe Lennox. Byron accommodation is very expensive & I know I won't opt to surf the pass.
