South Island is the smaller of the two islands that make up New Zealand, and it is made up almost entirely by a series of clear water lakes and glacial mountain peaks. It is this diverse landscape which captures the hearts of visitors year after year, and which makes it the perfect place to come on a mountain retreat. When you’re here, it’s best to choose a secluded mountain rental to stay in for the duration of your trip, as it will keep you in the heart of nature. Head to Fiordland National Park, where you can catch vibrant natural colors amidst a collection of majestic mountains. Here, you can hike along the rocky ground, or you can boat across the serene waters of Milford Sound to catch the best views.
