Bregenz

The world's largest floating stage, its monumental opera sets rising out of the lake. Dogs cannot attend performances, but the set is best admired by day from the free promenade, dog on leash.

Bregenz's mountain at 1064 m: a dog-friendly cable car (small dogs free), a panorama over the whole lake and 240 Alpine peaks, forest trails for the descent.

A free alpine wildlife park on the summit loop: ibex, marmots, deer and wild boar. A rare privilege, leashed dogs may walk the 30-minute circuit.

The emblem tower of the medieval upper town, capped by its huge 1601 baroque onion dome. The quiet cobbled lanes of the Oberstadt around it make the ideal leashed town walk.

The lakefront gardens between the harbor and the festival house: lawns, old trees, free waste-bag dispensers and continuous views over Lake Constance. The evening loop of Bregenz's dogs.

The shoreline path from Bregenz harbor towards Lochau, with gravel accesses where dogs swim year-round. The town's unofficial dog beach, extended by the old Lochau ferry landing spot.
