We have a small farm, 27 acres between Arrowtown, (a historic goldmining town) and Queenstown, (the adventure capital of NZ). We can supply power/water/dump close to the house, or freecamping near our ponds, paddocks etc. You will be surrounded by mountains and lakes and can do as much or as little as you like. Check out www.arrowtown.com or www.queenstown.com for local information, photo's etc. It's a stunning part of the world.
We have a gravel driveway about 400 metres long up to the house, from a good tarmac road. There is a couple of tight turns and a bit of a hill but we have had truck and trailers up when building the house. If there is snow on the ground it gets a bit ugly but flat parking is available nearer the road without hook-ups.
We are around most of the year, even if we are not, a freecamping situation should still be fine. We have a holiday home so are usually there for a decent amount of time in summer. There is room on a packed gravel alongside the garage and other more private areas about the place, depending on rig size
Bungy jumping, skiing, lakes, heaps of world class restaurants/vineyards, sightseeing, golf (5 courses - some of the best in the country), untold hiking and cycling trails, jet boating etc etc etc. There is no shortage of attractions here, you wont have time to do it all.
