Found a 17-degree summer attraction in Hangzhou

Found a 17-degree summer attraction in Hangzhou, a summer resort. What's the experience of climbing in a cave? I found a free scenic spot in Hangzhou, where the constant temperature in the scenic area is only about 17 degrees. It's a bit cold to go in with short sleeves. You can also "climb" in the cave, the narrowest place is only enough for one person to pass, and the shortest place needs to bend over to pass. Detailed strategy: Address: Ling Mountain Scenic Area, West Lake District, Hangzhou (Ling Mountain Illusion) Opening hours: 9:00-17:00 Play time: 1~3 hours Parking lot: There is a parking lot in the scenic area/There is a Copper Mirror Lake parking lot nearby. Tourist flow: Very few, even less after 3 pm. Public transportation: Take the subway line 6 to Keihai Road Station B1 exit, after exiting the station, transfer to bus 539 at "Subway Keihai Road Station AB Bus Station", in the direction of Ruyi Tip, get off at Zhang Yu South Station, walk for 5 minutes after getting off the bus to the entrance of the scenic area, or you can take a taxi after exiting the subway station. Tickets: Full ticket 57 ten scenic area shuttle bus 30, students/children/70-year-old people have discount tickets, cultural and tourism benefit card free admission. ◆Note: The attraction is on the mountain, the visitor center is at the foot of the mountain, the shuttle bus is for going up and down the mountain, it is recommended to take the bus in summer, otherwise it will be very hot to walk up and down the mountain.
