Gobok Reservoir is a large farm reservoir covering 770,000 square meters. It was constructed to provide water for agricultural use, but an abundant amount of fish attracted many fishermen from across the country. This resulted in it being appointed as a provincial park. The park spans an area of 1,840,000 square meters and its nearby attractions include a forest, Yonggul Cave, and Sinheungsa Temple on Obongsan Mountain. The neighboring village is home to orchards for growing grapes, peaches, and pears.
The park has a large meeting square and an outdoor sculpture park for added leisure activities. The Millakjeong Pavilion offers a panoramic view of the reservoir. Food lovers will be delighted to find that there are many restaurants around the reservoir area specializing in hanbang-ori (herb duck meat) and megi-maeuntang (spicy catfish stew).
