At the NATO 185KM of Su St. Mary's City, from late June to mid-October every year, there is a tourist train every day, you can take a day trip, depart from the city at 8 am, arrive at 12 o'clock, get off the bus and play, go back at 13:30, and return to the city at 17:30. No parking along the way, forests, lakes, canyons, pure natural scenery, dotted with few holiday villages. The best season is from late September to early October. Walking through the fiery autumn leaf forest, the scenery is amazing!
