There is a full glass lookout platform located in the Yalong Bay Tropical Paradise Forest Park in Sanya
The ticket for the platform alone is 98rmb/person in addition to the entrance ticket to the park. We got the set ticket for 258rmb/person which includes the entrance ticket, in-park buggy rides, zipliner, 5D film, and the platform - I recommend this! Promo is only until end of September
Compared to the other glass bridges/ walkways in China, this one is much easier to handle for people who are afraid of heights
If you are afraid of heights, there is a super pretty rainbow staircase too, perfect photo spot!
