Gwangmyeong Theme Cave

Originally opened in 1912 during the Japanese colonial occupation as the Siheung Gold Mine, Gwangmyeong Cave was a site of heavy industrial resource extraction and forced Korean labor, producing hundreds of kilograms of gold, silver, copper, and zinc. Abandoned following devastating floods in 1972, the labyrinth of subterranean tunnels served as an obscure salt-pickled shrimp storage cellar for decades until 2011, when the City of Gwangmyeong acquired and transformed it into a world-class industrial heritage theme park.

Extending over 7.8 kilometers across 8 subsurface levels reaching a depth of 275 meters (with 2 kilometers open to visitors), the cave maintains a natural year-round ambient temperature of 12°C to 13°C. The interior features awe-inspiring thematic spaces: Wormhole Square, the Light Space illuminated by thousands of fiber-optic LEDs, Cave Aqua World filled with native Korean and exotic freshwater fish, the 9-meter Golden Waterfall, the Golden Palace with statues of the god of wealth, and the 350-seat Cave Arts Hall equipped for 3D projection mapping spectacles.

Spring offers a comfortable, temperature-stable excursion away from unpredictable outdoor weather. Summer makes the cave one of the most popular subterranean cooling sanctuaries in Korea, drawing crowds seeking relief from sweltering heat waves while enjoying late-night wine tastings and cave horror festivals. Autumn pairs subterranean touring with colorful foliage hikes on Mount Gahak, while winter keeps visitors warm inside the 12°C climate-controlled passages.

Gwangmyeong Cave operates Tuesday through Sunday from 09:00 to 18:00 (last entry at 17:00). During the peak summer vacation window (July through August), the cave operates without Monday closures and extends hours until 20:00. The best visiting time is morning around 10:00 or late afternoon at 15:30 to avoid midday weekend tour bus congestion. Bring a light jacket or cardigan, as the subterranean air remains crisp even in midsummer.

Admission is 6,000 KRW for adults (19-64), 3,500 KRW for teenagers (13-18), and 2,000 KRW for children (3-12). Seniors over 65 and infants under 3 enter free. Tickets can be purchased at the main ticketing booths or online. Tasting flights and bottles of over 170 varieties of domestic Korean wines are available for purchase inside the Wine Cave.

From central Seoul, take Seoul Metro Line 1 or high-speed KTX to KTX Gwangmyeong Station. From Exit 7 or 8, board city bus route 17 or 77 which connects directly to the Gwangmyeong Cave Terminal in approximately 10 minutes. Ample multi-tier parking lots at the base of Mount Gahak charge 3,000 KRW for standard passenger cars.

The main entrance and the primary subterranean artery leading to Wormhole Square, Cave Aqua World, and the Wine Cave are level, paved, and equipped with ramps accessible for assisted wheelchairs and strollers. However, descending into the lower depths of the Golden Waterfall, Underground Lake, and Dragon's Lair involves climbing steep industrial steel stairways with approximately 300 steps where mobility assistance is required. Accessible restrooms are located at the outdoor plaza and inside the Wine Cave.

Inside the cave's Maru de Cave restaurant, upscale European dining is served directly inside the subterranean rock vault.

Vegetarian diners can enjoy customized plant-based dining: vegetable stone pot bibimbap, meatless hand-torn noodle soups (sujebi), and savory mushroom pancakes served in traditional dining rooms along Gahak-ro. The outdoor cafe plaza serves warm sweet-potato lattes, soft ice cream, and artisan pastries.

Unforgettable photo spots: the glowing tunnel of fiber-optic lights in the Light Space, standing beneath the 9-meter roaring subterranean Golden Waterfall illuminated in bright amber light, posing alongside the massive 41-meter cinematic Dragon sculpture crafted by New Zealand's Weta Workshop, and holding a wine glass against the oak barrel cellar in the Wine Cave.

Due to the 12°C underground temperature, wearing comfortable walking shoes and bringing a warm outer layer is essential. Running or touching historic mining rock faces is prohibited for safety. Pets are not permitted inside the subterranean tunnels. Smoking, outside food, and alcohol outside designated wine areas are strictly prohibited.

Emergency medical stations and nursing facilities operate at both the main ticketing plaza and the underground central hub. Automated external defibrillators (AEDs) and emergency emergency exits are situated throughout the 2-kilometer circuit.

Q: Is the cave cold in summer? A: Yes, Gwangmyeong Cave naturally maintains a steady temperature between 12°C and 13°C all year round. Even on 35°C midsummer days, the interior feels like an air-conditioned cellar, so bringing a light jacket or windbreaker is strongly advised.
