The Marlborough Sounds is a network of sea-drowned valleys located at the northern tip of New Zealand's South Island. This stunning region features a series of deep, narrow inlets and lush green hills, making it a popular destination for outdoor activities such as hiking, kayaking, and boating. The Sounds are known for their rich marine life and beautiful scenery. The area is also home to several small towns, including Picton, which serves as a gateway for ferry services to the North Island. The Marlborough Sounds are part of the larger Marlborough region, famous for its wine production, particularly Sauvignon Blanc.
