Frequently asked questions

Can I fit flower fields, aquarium and waterfall into one night?

These courses visit Mito historic sights on day one, then choose either park or aquarium on day two. The waterfall needs a Suigun Line return and about 40 minutes on foot from the station. For all three, compare three-night course B, visiting each on a different day.
