Great walking trails on these Wither Hills - there is already at least 40 caches scattered around here so now there is one more.
This will take you approx 35-40 mins to get here from the top of Redwood Street carpark. A nice meander along a flatish track to the picnic area (and a toilet if you need it) and then a short grunt up the "zig zag" track heading up to Mt Vernon.
Cache is a 200ml sistema with a couple of kiddy toys in it and a TB
Make sure you check out a few more caches on your treks up these hills on a fantastic Marlborough day.
