The itinerary was well-organized, and the tour guide service was excellent. It's a pity that there were only a few red leaves at Jozankyo and Fengping Gorge, but the scenery was still very beautiful.
Lake Toya's attractions are scattered across various locations, so it's possible to join a guided tour to each site. The guide will explain the attractions and the experience. Purchasing a fireworks boat ticket is also worthwhile.
