I love Thessaloniki, really, but driving around and parking is a nightmare! The only way to avoid it is to arrive in the evening, after the shops close and park in strategic locations close to the center. Alternatively, you can stop in Kalamaria, on the sea and move around by public transport or use the free RV area, 18km in the direction of Chalkidiki.
Enlarge MapLet’s start with three convenient parking spots for visiting the city, but where it is impossible to find a place between 8am and 8pm on weekdays. They are just over a kilometer away from Aristotelous Square and the locations are ‘safe’. Thessaloniki, in principle, has no security issues, no comparison with Athens, so to speak. On the occasion of the documentary festival I left my camper parked for ten days in the same place, not far from the first parking listed below, with no problems of any sort.

Parking is also suitable for long motorhomes. Located 18km from the center instead is the free camper stop Zampetas [40.50261,22.97040]. It is a dealer and repair shop specializing in RVs. It is not very easy to come and go from the city, but it’s manna from heaven to be able to load and drain the tanks and in the case longer stays, it also provides power connection, Wi-Fi and a washing machine … all for free! Open from 9am to 9pm, guarded 24h.
