I went to Sanumul Shelter Auto Campingjang with coworkers. It was my first time, but some colleagues were experienced campers, so I was able to relax and really enjoy it. There is a reservoir behind the campsite and a lure-fishing area, which I liked a lot. The air was fresh, and facilities like the restrooms were well maintained, so I was satisfied. The only drawback was the mandatory quiet time requiring everyone to be asleep by 11:00 PM, but other than that everything was perfect.
