Starting from Hakata, Fukuoka, taking a day tour by bus is a great option, eliminating the hassle of transfers. The tour started with the Kanmon Strait and the Akiyoshi-dō limestone cave, followed by an elevator ride to the Akiyoshidai Karst Observatory. We had burdock noodles at Azumiya for lunch, then visited Motonosumi Inari Shrine and the Tsunoshima Bridge. The pace was excellent, and I think it was well worth it. A big thank you to our enthusiastic guide, Thomas, who was professional and attentive, taking many great photos for me.
