Gria Vathra

Gria Vathra sits close enough to Therma that it works as a half-day option rather than a full hike — a series of smaller waterfalls and rock pools reached by an easy path, good for families or anyone who wants the classic Samothraki swim without the longer walk that Fonias demands.

The name translates roughly to "old woman's pools," tied to local folklore rather than any obvious feature of the place itself.
