With its unique volcanic geological features, clear waters, gentle sandy beaches, fine and even sand, and well-preserved native vegetation make for a picturesque coastal scenery. The crater is typical and well preserved. This island is currently known as the world's largest and densest basalt rock column group. It is mysterious and spectacular. The natural fresh air system created by hot air balloons and iron towers is also a good place to take pictures. It is very interesting to stay in the RV here.
