I don't think they would have any warungs out there
They had a land camp back in the day but the last time I was out there it looked like it was just left to rot
It was like a little abandoned village that was falling to pieces
I think the best bet would be to hire a feral boat and time it with a decent swell
The charters would be a bit hit and miss with conditions and way more expensive
Personally I wouldn't be too keen on camping especially if something went wrong at One Palm
Heavy waves out that way
Worth going though
