Be sure to have enough gas in the tank, because Fukuoka is well worth a detour. Located 25 miles from Karatsu, it offers up some terrific attractions, such as PayPay Dome and Fukuoka Tower. Nagasaki, 50 miles away, is another destination that’s worth the trek. Stop by Glover Garden and Nagasaki Atomic Bomb Museum, two top-notch attractions in the area.
