From blue-misted mountainous national parks wreathed in stunning autumnal foliage, colourful imperial palaces set against picture-perfect backdrops, and dreamy traditional Hanok villages nestled into lush valleys to vibing avant-garde enclaves like spaceship-style Dongdaemun Design Plaza hosting trailblazing events, the Common Ground shopping mall made entirely of shipping containers hosting high-end boutiques, and thematic high-octane mega parks like Everland, Seoul exhilaratingly blends the ancient and futuristic into a seamless duet. If you’re looking for deliciously surreal hi-tech experiences that portals you into kaleidoscopic realms, visit the many themed tunnels of this gold and silver mining cave, which will spin you into galactic vistas, underwater kingdoms, and unearthly plays of light.
