While this geopark encompasses about 108 sq km of rural countryside, the main attraction here is a corny tourist park surrounding a (genuinely cool) extinct volcano cone. Make haste past the snack stands and gift kiosks to descend the stairs winding down into the lushly vegetated crater, which feels more like a cave. Then climb back up for luscious views of the countryside all the way to the sea.
The geopark entrance is about 18km west of Hǎikǒu. To get here, first take a taxi to the T-intersection of Xiuying Xiaojie and Xiuying Dadao (秀英小街、秀英大道) and then catch one of the frequent minibuses (¥4, 30 minutes) to Shíshān County (石山镇, Shíshān Zhèn ) from the bus stop on the far side of Xiuying Dadao. A taxi to the park costs ¥60.
