It was great!! There are guides who can speak Korean, Japanese, Chinese, and English, and they are kind and repeatedly provide guidance and explanations!! They immediately answer any questions and are very thorough!! I didn't include lunch, so I was worried if I wouldn't be able to take the free shuttle and would have to eat onigiri on the bus, but it was great that I could use the taxi shuttle (300 yen per person) and restaurants near the volcano museum!! However, the price of the restaurant meal wasn't much different from the bulgogi that comes with lunch, so I think I'll have lunch next time.. haha. Instead, the restaurant next to the museum has a variety of menus!! The taste was also good!! Horse meat is famous? And red beef is also famous.. The rice is also famous for being delicious, so I had wagyu donburi, horse meat yukhoe bibim, and ramen, and the wagyu donburi was expensive but incredibly delicious... Horse meat yukhoe bibimbap is not recommended.. It tastes good, but when the rice, sauce, yukhoe, and raw egg are mixed, it becomes a bit mushy..? So, the ramen was also delicious, and the rice itself was delicious!! It was even better because the miso soup and rice were unlimited!! And the milk soft-serve ice cream and volcanic ash coffee below were also delicious... Kusasenri was a bit disappointing because I couldn't see much due to the fog, but I enjoyed smelling the sulfur and the boat experience was a lot of fun!! Highly recommend the boat!! Anyway, I had a lot of worries, but the guide's leadership was skillful, smooth, and the schedule was kept perfectly, which was great!! I think I'll use it again next time! Gogotrip? Gogogo? Anyway.. they also explained history and myths, which was fun!!
