To find it, cross the little Borjomula River just east of Borjomi Park train station, turn right along 9 Aprili and go 600m. The original warm mineral spring, named Ekaterina Spring, sits beneath a pavilion straight ahead of the park entrance (you can fill bottles from it). The commercial Borjomi bottling plants today draw their water from other mineral springs – there are about 40 in the area.
