For a spectacular view over Castlepoint Beach including the lighthouse the track up to Castle Rock is an absolute must do.
Forming part of the Deliverance Cove Track, the track is rated an easy walk but getting up to this view point is a little precarious. DOC advises that access to the top of Castle Rock is not recommended as it is unsafe, and I do have to admit that it was a little scary being up there. The drop off below Castle Rock is just that, a huge drop into the ocean. The path is also very skinny, can be slippery and climbing over some rocks is required.
To get to the look out walk south along the beach and follow the track up through coastal grassland to the saddle. Once at the saddle you will see a skinny path to your left (when looking up from the beach), follow that until the reach the top of Castle Rock.
BEWARE: we encountered some very angry seals at the base of the path on the beach and hiding in the flax bushes (they like to snooze in the bushes). If the seals are around, enter at your own risk!
Best at sunrise and take your wide angle and mid zoom lens.
