Frequently asked questions
Can I fit the flower fields, aquarium, and falls into two days?
These itineraries visit Mito's historic sites on the first day and choose either the park or aquarium on the second. The falls need a round trip on the Suigun Line and a walk of about 40 minutes from the station. To see all three, compare an option such as three-night Option B, which visits each on a separate day.
