Use this route structure as a starting point, then adapt stops and timing with your group in Journii.
For day 1, we strategically grouped the most popular attraction, Château des ducs de Bretagne, with surrounding point of interests to start your trip off with a bang.
For day 2, we bundled attractions like Centre Commercial Atlantis and Zenith Nantes Metropole and other places within a close range, so that the time it takes to travel between all of them is less than one hour.
For day 3, we recommend exploring the south side side of town.
Turn this guide into a shared trip: add flights, accommodation, transport notes, and reservations so your whole group can edit one timeline.
