Mainau is a small island located near the city of Konstanz (Constance) on the western shores of Lake Constance (Bodensee), and it is accessible from Überlingen by ferry.

Located on the east end of Lake Constance (Bodensee) that borders on Austria, Germany and Switzerland, Lindau is a beautiful little town.  The old part of the town is on a small island connected to the mainland by a causeway.

Überlingen is also on Lake Constance (Bodensee) and is northwest of Lindau about a one-hour ride on a local train from Lindau.  It can, also, be reached from Constance by ferry.  The promenade on the lake front is a wonderful place to relax.
