I was surprised to find the ramp itself only just off the highway. I thought there would have been a bit of a drive through the scrub first. So no 4wd needed. The ramp is a good quality cement ramp typical of most creeks. The photos shown here are taken on a very low tide, probably 0.5m or so. Obviously the ramp is no good at this time, but it wouldn't take much more water to be fine for small boats.
Parking is simply in the gravel/dirt area around the ramp, but I doubt it gets very busy. There appears to be a toilet block, but I didn't investigate this at all.
