Kelson Hill can be equally easily explored by car, bicycle, public transport via the Route 150 bus, or on foot. The brisk walk from the foot of the hill will take you past several caches and offers some great views over the Hutt river, Wellington harbour, and Wellington city itself.
This cache is easily grabbed via a car, with on-street parking available right beside GZ.
Cyclists attempting this cache will no doubt enjoy the ride back down the hill - many cyclists use the nearby digital speed read-out sign to test their bravado when screaming downhill. We obviously don't condone this sort of behaviour, and encourage you to stay within the speed limit at all times :-)
