Mainau and Reichenau: gardens or World Heritage
Mainau is a ticketed garden island with seasonal displays; Reichenau is a lived-in agricultural and monastic landscape. They offer different visits and do not need to share one day.
Mainau is open year-round, but its displays change
Mainau publishes year-round visitor access, while opening details and the character of the gardens vary by season. The island includes a baroque palace and church, an arboretum and a butterfly house. Check its official opening and ticket information before travelling, especially if a particular floral display is the reason for your visit.
Mainau admission in autumn 2026
Day-visitor admission checked on 10 September 2026: Mainau opens 09:00–18:00 from 14 September to 4 October and 09:00–17:00 from 5 to 18 October. Individual attractions and restaurants have separate hours. Check the subsequent period separately; bicycles are not permitted on the island.
Reichenau centres on three Romanesque churches
UNESCO inscribed the Monastic Island of Reichenau in 2000. Its principal churches are the Minster of St Mary and St Mark, St Peter and Paul, and St Georg. Current conservation rules matter: St Georg is closed to general visits from May through September, with access in that period limited to guided tours according to Reichenau Tourism. Check church access before setting out. Reichenau Tourism currently lists public St Georg tours at 11:00 and 16:00 during the May–September conservation restriction; confirm the exact date in its event calendar. The Minster and St Peter and Paul are generally open 09:00–17:00, with some seasonal extensions. Group tours require prior arrangement.
Choose one island or verify the connection
Choose Mainau for formal gardens and family attractions; choose Reichenau for churches, history, agriculture and cycling. Both can be reached from the Konstanz area, but do not assume a direct boat connection between them. Check the current BSB route or use land transport and allow each island enough time.
Reichenau services cancelled on 13 September
On Sunday 13 September 2026, BSB services 613–620 between Radolfzell, Iznang, Mannenbach and Reichenau are cancelled completely. This notice applies to those services, not every operator on the lake. Check a land connection and the current operating notice before travelling.
Common mistakes that weaken the trip.
These are practical cautions, not live availability claims. Current ferry and boat timetables, garden seasons, opening hours, and cross-border rules still belong to official sources.
Expecting the same Mainau garden display in every month.
Arriving at St Georg between May and September expecting unrestricted entry.
Building a tight itinerary around an unverified direct boat link between the two islands.

Where to stay on Lake Constance: five useful base towns
Compare Konstanz, Meersburg, Lindau, Friedrichshafen and Überlingen by location, transport and the places you want to visit.
Getting to and around Lake Constance
Plan rail and air arrivals, BSB passenger boats, the year-round car ferry and catamaran, and the 260-kilometre Bodensee-Radweg.
Lindau and Meersburg: plan the towns separately
