Really nice park with a lot of space and a lot of things to see and do. Really nice and clean. The walk around the volcano (and down) is really nice. The price is a bit expensive, but still fair. The choice of restaurants inside the park is really not very good though.
The park covers an area of 108 square meters and is about 15 kilometers from Haikou downtown and boasts more than 40 volcanoes of Quaternary and is called a natural geological museum. You can overlook charming scenery of the city and Qiongzhou Strait upon in the highest crater in the park.
