Weizhou Island lies off Beihai in Guangxi, a volcanic island in the Gulf of Tonkin. It is often called China's largest volcanic island and among its geologically youngest. The coast makes the case: dark lava, rust-coloured rock, sea caves, arches and wide tidal platforms, with coral in the clearer water. Villages, guesthouses, fishing boats and market stalls set the rhythm here rather than resorts.
Getting there and getting around
Ferries leave from Beihai International Passenger Terminal. Book ferry tickets and island admission through official channels before you travel, especially around public holidays. Weather can cancel or delay sailings, so leave a spare day at either end. From Beihai railway station, local buses and taxis run to the terminal. From Beihai Fucheng Airport, take the airport bus into the city and change; it does not go directly to the passenger terminal. Drivers can park near the terminal and cross on foot.
On the island, bicycles and electric scooters are the usual way around. Check brakes, lights and battery before setting off, and keep speed low on narrow village roads.
A volcanic coast at Crocodile Hill
Crocodile Hill Scenic Area sits on the southern side, west of Nanwan and about four kilometres from the town centre. Paths pass the lighthouse, the crater site, sea arches, caves, coral-bearing sedimentary rock and volcanic bomb impact craters. The lighthouse is the island's landmark and a useful orientation point.
The walk is exposed. Carry water, wear a hat and use shoes with grip. Morning or late afternoon brings softer light and cooler air.
Beaches, tides and village lanes
Five-Colour Beach
Five-Colour Beach rewards early risers. At low tide the platform reveals layers of eroded rock; at sunrise the surface shifts colour. Check local tide tables before setting out. This is a geological platform, not a sand beach, and wet rock is slippery.
Shiluokou Beach
Shiluokou has some of the island's clearest water, low sediment and a soft sandy edge. It is also the base for diving and motorboat rides. Volcanic rock at the margins is jagged, and currents deserve respect. Swim only where local operators permit.
Dripping Water Cliff
Dishuidanping, in Dishi village, is a cliff face with greenery on top and water seeping through fissures, hence the name. The beach below is good toward sunset, when fishing boats sit on the sand and the light softens. It is a place to wait rather than rush.
Shengtang Catholic Church
The Catholic church at Shengtang is Gothic in style with French Renaissance influences, built in the late Qing period from coral, rock and lime. The stone facade and quiet interior feel far from the coast's exposed geology. The lanes around it are among the best places to see older village houses and everyday island life.
Nanwan market and the island table
Nanwan seafood market is where the local catch turns up. It is practical rather than staged: fishermen and vendors sell whatever the boats bring in. Pick fish, prawns, crab or shellfish, then ask the guesthouse kitchen to cook it. Agree weight, price and cooking charge before the pan goes on. Variety and quality shift with weather and season.
On the water
Motorboat rides, sea fishing and diving are part of the island's appeal. Arrange motorboats through a guesthouse or an operator with clear safety rules, and wear the life jacket rather than carry it. Sea fishing trips from Nanwan can combine fishing with views of the crater coast and Zhuzai Ling; ask what the route includes before booking. Diving concentrates off Shiluokou, where the clearer water and coral are the draw. Beginners can join guided dives; check that equipment is well maintained and the guide licensed.
When to go
April is often mild and clear, with fewer visitors. May brings warmer weather and the first typhoons. June is hot, and it is also a time for night squid fishing. July and August are the busiest months, with school holidays, strong sun and high humidity. September stays warm but quieter. October and November are generally comfortable, with clear skies and less intense sun, though the National Day holiday is a busy period. December to March is cooler; walking and sightseeing are pleasant, swimming less so. Weather patterns vary, so confirm ferry operations and sea conditions with official sources.
Practical notes
Accommodation is mostly guesthouses and small hotels; there are no large five-star resorts. Nanwan is convenient for the market and boat trips, Dishi for sunsets, Shengtang for village lanes and the church. Bring sun protection, drinking water and shoes that grip wet rock. Confirm current ferry times, island entry rules and activity availability with official or licensed operators; details change with season and weather.
