Camp at Moke Lake

The drive to Moke Lake from Queenstown is only 14km but it takes about 30 minutes since you're on a dirt road for a good portion of it. You'll pass Lake Kirkpatrick and lots of sheep on your way to Moke Lake, but keep driving until you get to the campground that's on the southeast end of the lake. Once you're there, finding the ~7km track that loops around the lake is pretty straightforward if you start it counter-clockwise. Just head down to the water and start walking along its edge, and within the first 500m or so you'll cross over a little wooden boardwalk and after that the well-formed trail just gently undulates along the east side of the lake. At the north end of the lake you'll go over 2 stiles to stay on the loop track, which is well signed, but you can also opt to walk to Lake Dispute as an out-and-back (~2hrs one way). After coming down along the hillier west side of the lake, the track eventually brings you to a stile and you'll find yourself on the road you drove in on. You can try to stay near the water, but it's a lot easier to make your way back to the start by following the road.

For camping, the campground is $10 a person per night and managed by the NZ department of conservation.
