Gwangmyeong Cave

Gwangmyeong Cave is a massive underground cultural space and former gold mine located near Seoul, featuring over seven kilometers of subterranean tunnels. It showcases illuminated light displays, immersive media art, themed zones like Wormhole Square and Aqua Cave World, as well as an underground lake and a dedicated wine cave.

Commenters largely praise the cave as a stunning, otherworldly attraction and a cool summer getaway ideal for dates. However, visitors frequently caution about challenging stair climbs, cold indoor temperatures, occasional humidity, and crowds during peak visiting hours.
