Propped against New Zealand's southern Alps, Queenstown is exploding with natural wonder and adventure at every corner. Your schedule can be as relaxed or full as you want it; take a helicopter ride to the mountains or drink in the views from a hot air balloon ride. There are wineries, lake cruises, guided tours, and, if you're feeling particularly brave, one of the world's tallest bungy jumps and swings. You can, of course, swing as a couple!
