the cave is something that you definitely have to experience in person for yourself! impressive sight. also, do try the burdock noodles right outside the cave! it was the best thing i ate on my trip. the view of the sea was more stunning than the torii gates imo, and the bridge wasnt too special. my guide was helpful and offered to help take photos, and seemed like a nice person, which i really do appreciate. however, it was hard to find the tour group at the gathering point and you have to ask around to find your guide. it also felt like the guide was overwhelmed by the large tour group size, especially when guide’s chinese is noticeably better than english. i could understand both languages, so it was clear when some info wasnt mentioned in english, and i felt bad for the english-only speakers on the tour.
