The car park at Lake Constance Forum offers convenient parking options for visitors. If you park here, you can also purchase bus tickets to the city center. The bus stop is only a 6-minute walk away. The parking fee includes bus tickets for 2 adults and 2 children. From there, it takes about 20 minutes to reach the old town, located along the beautiful banks of the Rhine.
The parking can be challenging to find as GPS systems can get confused. To access it, take the third exit at the roundabout after coming down from the bypass under the viaduct. The parking ticket costs €3, but if you use public transportation, it's €5 and covers 2 adults and 2 children. The Line 6 is a convenient option.
We stayed here overnight - 5 euros for 24 hours for two people and a bus. There was a public toilet nearby, although it was well-lit at night and there was a construction site next to it (but it didn't bother us).
