I would definitely add this to your list of places to visit in Okinawa. I mostly went for the cave, which definitely lived up to the hype. The entrance is all done up like a Disneyland ride (which is cool if a little inauthentic) but the inside is amazing. The cave is enormous and it takes awhile to walk through. At first it's crowded because everyone is stopping to take photos, but the crowds thin out as the cave goes along, as people mostly walk through and stop taking so many photos. I had never been in a cave that immense before! The path crosses some underground rivers as well. I thought the price of admission was worth it just for the cave. The Eisa show is a must-see. I really enjoyed the piece of Okinawan culture. The snake show, however, is a little rough. It's quite boring, nothing really happens, and it's not very humane for the snakes or mongoose. I would skip the snake show and see the Eisa show. There are also a bunch of local crafts you can try out. I'd recommend picking one or two before you go and planning to spend some time making something. My favorite was impressing designs into leather. You can also get a photo with a python on you (not necessarily unique, but fun), and try locally brewed beer or habu sake (literally sake with a dead habu in it? I didn't try it but maybe worth the experience?) I think I spent around 4 or 5 hours here, but you could easily do it in 3. Be warned the place selling local beef closes really early. Also if you're relying on public transportation, don't miss your bus back because they do not come often. If you have a half day or more, I would recommend this place!

Place seems big but there’s a lot of add-on activities at additional cost. The cave was nice but was warm and humid, quite a long walk and could be slippery, so do be prepared to walk. Strollers have to be left outside and it’s quite a walk back to the entrance from the exit of the cave.

Okinawa World is a must-go place! For the ticket price, it’s totally worth it! You get to visit Gyokusendo Cave (which is a limestone cave), watch 2 shows (Snake & Mongoose Show + Eisa Cultural Performance), view some traditional Okinawan home setups and visit the snake museum! Good to allocate ~ 3 hours there. And if you want to take it more leisurely, perhaps 4 hours.

It was a hot and humid day. I was looking forward to the coolness of the long cave walk. Much to my surprise it was just as hot in the cave. Every other cave I've been in has been 55 degrees F (about 13 C). The lighting was also poor in relation to where potential obstacles were. This is not a fault of the cave but I am tall so having to stoop most of the time was tiring. The actual sights in the cave were quite interesting. The other attractions were pretty good once I recovered from the cave walk, especially the crafting demonstrations and the snake museum
