The surfing, obviously, is all on the backside of the island, and you’ll need someone with access to the Conservancy land, as it’s all gated off. If you can get there, or find someone at CIMI (Toyon Bay) who’d be psyched to go, you could do it. And there’s always someone psyched to go, maybe you know someone who lives out there? That’d help a ton.
I’ve never heard of epic perfect waves or anything, but here’s a rundown of what I’ve seen/surfed/heard;
Ben Weston - a beautiful beach with a treacherous descent from the road, with a decent beach break. Conditions really improve (or worsen) depending on the wind.
Salta Verde Point - never been down there - you need a boat I think, but evidently it’s pretty sweet with a southern swell.
Shark’s Cove (I think that’s what it’s called, though I’m only 70% sure), is another decent beach break right between Little Harbor and Ben Weston. It break’s bigger, if I’m remembering correctly, than BW, but more sloppy. Sidenote: I sailed/snorkeled/chilled on the island and heard about sharks, but never had any problems, i.e. sift through the hype.
I haven’t heard anything about north of the isthmus, but I would imagine that there could be some stuff. A lot of unexplored terrain, or minimally explored maybe, which is cool. It’d be nice to have 2 weeks and a 40’ sailboat with a quiver, and some Santa Ana winds blowing offshore.
That’s what I live for…
The problem, again, is access.
