Ruine Stein
Begin where Baden once kept watch. The Ruine Stein, called Stein Castle in English and Schloss Stein by some locals, is what is left of the castle above the town, and Switzerland lists it as a heritage site of national significance. That ranking is the reason to start here: before you meet the spa town, you meet the fortress that stood over it.
The ruin is open around the clock and free, so the hour is yours. Walk around the old walls, get a sense of how the town spreads out from here, and keep in mind the shape of the day ahead: you start above the rooftops with stone and end at river level in hot water.
From the ruin it is 1,040 m, about 16 minutes on foot, to the Kurpark Baden.
