The maritime township of Picton (population 4,000) lies at the head of Queen Charlotte Sound and is the arrival point for ferries from the North Island, as well as a growing number of international cruise ships. It plays a major role in providing services and transport by water taxi to a multitude of remote communities in the vast area of islands, peninsulas, and waterways that make up the Marlborough Sounds Maritime Park. There's plenty to do in town, with crafts markets in summer, historical sights to see, and walking tracks to scenic lookouts over the sounds. The main foreshore is lined by London Quay, which looks up Queen Charlotte Sound to the bays beyond. High Street runs down to London Quay from the hills, and between them these two streets make up the center of town.
