If you want to partake in a restorative hot tub just like the Romans did, look no further. The ancient Pamukkale swimming pool (next to the Temple of Apollo) allows you to cool off your muscles after an exhausting travel with the mineral-rich hot spring water of 36°C. It might be the most enthralling hot spring experience you'll ever have, with half-submerged columns and pieces of fallen marbles scattered in the water all around you.
