Freiburg sits 400 km from the nearest sea but is rich in summer river and lake swimming for dogs. The Dreisam river runs across town with shallow tolerated dog swimming sections, the Opfinger See lake west of the city has an official Hundebadeplatz, and the Black Forest lakes of Schluchsee and Titisee are an easy day trip.
Opfinger See, 79112 Freiburg im Breisgau
Former gravel pit on the western edge of the city, now a clean swimming lake. A signed Hundebadeplatz on the north shore offers 150 m of grass-and-gravel entry with shallow water, the easiest in-city dog swimming option.
💡 Bus 33 from Freiburg Hbf to Opfingen, then a 10-minute walk. Water heats to 22 to 24 degrees in July and August.
Schluchsee, 79859 Schluchsee
The largest lake in the Black Forest, 930 m above sea level and 45 minutes east of Freiburg by car. Two signed Hundestrand zones at Aha and at the southern Wolfsgrund offer grass banks and clear shallow swimming.
💡 Direct regional train (Höllentalbahn) from Freiburg Hbf to Schluchsee in 1h15. Stays cool (16 to 22 degrees) all summer, ideal for thick-coated dogs.
Titisee, 79822 Titisee-Neustadt
The Black Forest's most famous postcard lake, 30 minutes east of Freiburg by regional train. A small but well-signed Hundestrand on the eastern shore at Bärenhof offers shallow swimming with the mountain backdrop.
💡 Titisee fills with tourists from June to August; arrive before 10:00 or after 17:00 for a calm dog swim.
