Weizhou Island, the largest volcanic island in the country measuring in at 24 km², lies 36 nautical miles from Beihai city. The volcanic stones, solidified lava formations and the wide crater provide some unusual scenery. Eighty-five percent of the island's 16,000 residents are Hakkas (Kejia), who make their living from fishing and tourism. The island is a peaceful place to stroll the narrow streets of the villages and visit the old Roman Catholic Church, a scale model of Notre Dame in Paris. Seafood is abundant and sold at an extremely low price. Souvenirs made from marine products are on sale in stalls on the streets. Give yourself at least half a day or more to visit the island.
