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. The easiest way to get here is to take tourist bus 1 (¥30, 45 minutes, 8.30am and 12.30pm) from Báishāmén Park. The return bus leaves three hours later. A taxi to the park costs ¥60.
