The first thing to know: you can't really swim in Thessaloniki itself. The city's seafront is a handsome stone promenade, not a beach, and the water along the central gulf isn't for bathing. But the real beaches are closer than most visitors expect — a string of sandy resort towns curls southeast along the Thermaic Gulf, the nearest barely half an hour away, and several are reachable by public transport. Here's where to go for a quick dip after sightseeing, and where to head for the cleanest water.

Peraia, Nei Epivates and Agia Triada — the easy options
The closest swimming is the resort coast directly across and southeast of the gulf. Peraia is the nearest and most accessible: a sandy, shallow, family-friendly beach backed by a lively seafront of cafés, tavernas and beach bars, with a long pier that's a sunset favourite. Nei Epivates runs on from it in an almost continuous sandy strip, and Agia Triada a little further is calmer, well-organised with sunbeds, and home to a big seaside campsite.
These are urban resort beaches rather than wild coves — easy, cheerful and busy in summer, with everything (umbrellas, showers, food, drinks) on hand. Don't let "urban" put you off, though: Peraia, Nei Epivates and Agia Triada all hold 2026 Blue Flags for water quality and facilities, so the sea is cleaner than the shallow, crowded shoreline might suggest — it's just calmer and less crystalline than the wilder stretches further out. For a half-day swim without committing to a full Halkidiki day trip, they're ideal.
Epanomi — wilder and cleaner
If you have a car and want better water, carry on to Epanomi, about 40 minutes from the centre. Its Potamos beach is longer, more natural and noticeably cleaner — a wide stretch of dune-backed sand with a more laid-back, less built-up feel. It pairs nicely with a visit to the Ktima Gerovassiliou winery and museum nearby — a highlight of our wine tours guide. Bus service here is sparse, so this one really wants a car.
How to get there without a car
- Bus — the suburban 72 line runs from the IKEA / Nea Paralia area out to Nei Epivates and Agia Triada; it's slow but cheap and doesn't need a car.
- Summer ferry / water taxi — in the warm months a boat runs from the city waterfront across to Peraia (and sometimes the Nei Epivates pier), which is the most pleasant way to arrive — a short cruise with a view back at the skyline.
- Car — fastest and most flexible, especially for Epanomi; about 30–40 minutes down the coast road.
- Taxi — reasonable to Peraia if you split it, and handy for a spontaneous afternoon.
Which beach should you pick?
For the least effort, take the summer ferry to Peraia and walk the seafront between swims. For a calmer family day, Agia Triada. For the cleanest water near the city, drive to Epanomi. And if you have a whole day and want the turquoise, Blue-Flag Greece of the postcards, skip the gulf entirely and head to Halkidiki — about an hour to the first Kassandra beaches, where it's worth knowing in advance which stretches charge for a lounger and which stay free, as our Halkidiki sunbed guide sets out. Either way, building a swim into a summer trip is the smartest way to handle the city's heat — see Thessaloniki in summer for the season's rhythm.
Frequently Asked Questions
Can you swim in Thessaloniki city?
Not really. Thessaloniki's central seafront is a stone promenade (the Nea Paralia), not a beach, and the water along the city is not meant for swimming. For a swim you head southeast along the Thermaic Gulf to the resort beaches — the nearest, Peraia, is only about 30 minutes away.
What is the closest beach to Thessaloniki?
Peraia is the closest proper beach, roughly 19 km (about 30 minutes) southeast of the centre — a sandy, shallow, family-friendly resort beach with cafés and beach bars. Nei Epivates and Agia Triada continue along the same coast just beyond it.
How do you get to the beach from Thessaloniki without a car?
Take the suburban bus 72 from the IKEA / Nea Paralia area toward Nei Epivates and Agia Triada, or — in summer — the seasonal ferry / water taxi from the city waterfront across to Peraia. Both reach the close gulf beaches without a car; Epanomi and Halkidiki are easier with one.
Which beach near Thessaloniki has the cleanest water?
Of the easy options, Epanomi's Potamos beach (about 40 minutes by car) has the cleanest, most natural water — a wilder, dune-backed stretch, though it's the resort beaches closer in (Peraia, Nei Epivates, Agia Triada) that carry the 2026 Blue Flags. For the very best swimming, though, it's worth the full hour-plus to Halkidiki, Greece's top Blue Flag destination.
