"Camel's Hump" is a small hill on top of the ridge in Maungaraki, Lower Hutt. The start of the track up Camel's Hump is located on Otamarau Grove - look for the sign at the start of Karearea Lane (no exit - private driveway).
From the top you get good views of Belmont Trig and the Korokoro Valley, as well as over the western hill suburbs, but it can get very windy.
The cache is a small container which only includes a notebook - bring your own writing implement. Note that there is no need to fossick through any gorse to access the cache.
