The site was abandoned as a quarry in the 1990s before being transformed into an eco-friendly cultural park in 2009.
The lake, Cheonjuho, reaches depths of approximately 20 meters.
The water in the lake is clear enough to support the 1st-grade level of water quality, allowing for fish habitation.
The vertical granite cliffs surrounding the lake are the result of decades of mining, which left the rock faces exposed.
The park's astronomical museum features a planetarium and a space experience center.
Several scenes from Korean television dramas, including 'Moon Lovers: Scarlet Heart Ryeo', were filmed at the Cheonjuho quarry site.
Pocheon Art Valley is a multifunctional park built within the site of a former granite quarry. The central feature is Cheonjuho, a turquoise lake formed by trapped spring water and rainwater filling a deep granite canyon. The site includes an astronomical science museum and an outdoor sculpture garden featuring granite-based installations. Vertical cliff faces rise 20 meters above the water, showcasing the site's industrial past. A monorail system assists visitors in navigating the steep incline from the entrance to the main quarry lake. The park serves as a cultural venue, hosting regular concerts and performances on an outdoor stage. It is located in the northern region of Gyeonggi-do, approximately 60 kilometers northeast of Seoul.

Wear comfortable walking shoes as the path from the entrance to the lake involves a significant incline.
Utilize the monorail for the uphill journey to save energy, then walk down the paved paths to explore the sculptures at a leisurely pace.
Bring a light jacket or extra layers, as the canyon and lake area often experience cooler temperatures than the surrounding valley.
Avoid visiting during heavy rain, as the outdoor walking paths and the monorail may be restricted for safety.
Closed the first Monday of every month for maintenance.
Stick to designated walkways; do not attempt to enter or swim in the Cheonjuho lake.
