The Pozar thermal springs discharge at 37°C year-round from fissures in the Voras massif, fed by aquifers heated deep within the mountain's volcanic substrate. First documented in Ottoman cadastral records of 1675, the springs gained their modern infrastructure in 1952 when the Greek state carved channels through the limestone to create bathing pools. The outdoor basins lie beneath a rock face draped in ferns, where mineral-rich water flows continuously into stone-lined chambers open to the sky. Today the site operates as Loutraki Aridaias, a spa complex 100 kilometres northwest of Thessaloniki that combines free-access natural pools with a paid wellness centre. Edessa, 40 kilometres west of Pozar, anchors its identity to the Vodas River, which drops 70 metres over a tufa cliff in the town centre. The Karanos waterfall—named after the semi-legendary founder of the Argead dynasty—creates a curtain of spray visible from the plateia below. Behind the cascade, a footpath tunnels through the rock, allowing visitors to stand inside the falling water. The ancient Macedonian capital of Aigai lay 15 kilometres south; Edessa served as a garrison town controlling the Via Egnatia's northern spur. By the Byzantine period, watermills lined the riverbanks, grinding grain for the Thessalonian hinterland. The mills are gone, but their stone foundations remain embedded in the park's retaining walls. Pozar thermal baths and Edessa day trip from Thessaloniki itineraries typically allocate two hours at the springs and 90 minutes in Edessa's waterfall district. The thermal water at Pozar contains sodium, calcium, and trace radon—concentrations measured by the Aristotle University's geology department in 2018 found levels consistent with therapeutic classification under EU standards. The outdoor pools require a four-euro entrance fee; bathers receive access until 02:00 on weekdays and 04:00 on Saturdays. Most organized tours from Thessaloniki include optional stops at family-run tavernas in Aridaia, where regional staples like pork with leeks and barrel-aged wine appear on fixed menus. The drive from Thessaloniki follows the E86 northwest through the Axios valley, passing tobacco fields and the Goumenissa wine appellation before ascending into the Almopia foothills. Pozar lies at 390 metres elevation; Edessa sits higher at 320 metres on a plateau overlooking the Thessalian plain. Winter snow closes mountain roads sporadically, but the springs remain open. Summer weekends draw domestic visitors; early morning arrivals on weekdays find the pools nearly empty.
