Hankø is well known internationally as a venue for the sport of sailing, having hosted several world championships in different yacht classes. It is the host of annual sailing competitions in the summer, drawing international competitors in many classes including the Melgis class. The island has many summer cottages, mainly owned by inhabitants from Oslo (Norway's capital). This is due to the close proximity to the capital. The island is connected to the mainland, at a beautiful place called Vikene, by a ferry, going to and fro as the need arises. There is a hotel on the island with a spa (after recent refurbishment), which is heavily dependent on corporate customers.
