Southland is known for its natural beauty, from mighty rivers and forests to stunning glaciers and mountaintops. It can be stressful to cram all the sights into your itinerary, however. This fast-paced tour of the Twin Lakes removes some of that stress. Travel in a jetboat down the Waiau River to Lake Manapouri. Then switch to a helicopter and fly to the top of the Jackson Peaks, where you can take in panoramic views of Fiordland National Park.
