One of the most famous visitors and, I assume, regular bathers, was Rabbi Yehudah HaNasi, the codefier of the Mishna. Keen to know that their ablutions and exercise were 'under rabbinic supervision', the hot springs became very popular with other scholars and residents. Most of the Roman buildings have been excavated and partially restored and a modern mineral spring resort has been built on the site. The modern site now blends the soothing comforts of the geothermal mineral pools with fascinating Roman excavations and architecture. By the way, when I say hot, we really mean HOT. With water temperatures ranging between 40 - 52 degrees Celsius, well over body temperature, you may want to take medical advice before swimming.
Hammat Gader is well signposted off Route 7599. Turn right at Tzomet Hammat Gader on Route98, which runs along the Jordanian border at that point.
