If the aquarium anchors a wider Kagawa day, a chartered day tour from Takamatsu can combine it with Kotohira or the Seto coast without wrestling local train timetables.

02What makes it work

The aquarium is strongest when it is part of a relaxed regional day rather than a rushed checklist. If the broader route already involves long drives or ferry timing, adding another scheduled stop may weaken the day.
