The Thermi Ecological Park, located about 20 km southeast of Thessalonoki, is the start point of a series of hiking areas, nature preserves, and mountain bike parks. The area features a massive network of roads, trails, and paths that are also great for trail running. There’s something for all abilities — some flatter, easier sections and some more rugged, hilly trails.

The closest point to Thessalonoki is the area around the Thermi Ecological Park (Περιβαλλοντικό Πάρκο Θέρμης). The terrain becomes increasingly rugged and hilly east of there, toward Mount Chortiatis (Xortiatis).
