Twelve Mile Delta is a very relaxed but popular place for fishing and a picnic about 11km west of Queenstown along the Glenorchy Road which takes about 15 minutes drive. Its situated in a beautiful spot right by Lake Wakatipu and a small river with a beautiful walk available to Bobs Cove which takes about 1 hour 30. The walk is clearly sign posted and is suitable for people with a low to moderate fitness level.
Accommodation is available here at the camping ground which is located on a gravel river delta. It costs $7 per person per night and is run by the Department of Conservation. Toilets are available and water is available from the small river or the lake. Dogs on a lead are permitted. Reviews of the campsite are available at Rankers
