Ask anyone who returns to Halkidiki year after year which of the three peninsulas is the most beautiful, and most will answer without hesitating: Sithonia. It's wilder than Kassandra, with pines running down to the water and turquoise coves that reinvent themselves every few kilometres. The only real problem is choosing — we've mapped over 60 beaches here alone. This guide lines them up, coast by coast, so you don't waste kilometres.
Northwest coast: Nikiti to Neos Marmaras
The most convenient zone for first-timers — asphalt everywhere, facilities, and sunsets over the Toroneos Gulf.
- Kastri: The classic organized choice near Nikiti — Blue Flag most years, shallow bottom, pines. Next door, free Mikro Kastri for those who want quiet.
- Lagomandra: Two kilometres of sand with a gently shelving bottom — some of west Sithonia's best sunsets.
- Paradisos: Near Neos Marmaras, relaxed and easy to combine with a stroll in the town.
Northeast coast: Vourvourou and the Diaporos gulf
The most photographed corner of Sithonia — shallow, sheltered sea scattered with islets.
- Karydi: White sand, pool-like water staying shallow for 60+ metres, sculpted rocks at the edges. The most famous beach of Vourvourou — in August arrive before 10:00.
- Livari: A shallow lagoon facing Diaporos island — this is also where you can rent a licence-free boat to tour the islets.
- Trani Ammouda: At Ormos Panagias, light sand and calm water — the Mount Athos cruises also depart from here.
East coast: from Kavourotripes to Sykia
Sithonia's postcard: granite rocks, orange hues and Mount Athos on the horizon.
- Kavourotripes / Portokali: The most "exotic" scene in Halkidiki — white rocks, turquoise water, a string of small coves. Reached by a path down; not for pushchairs and trolley umbrellas. Right next to it, Mega Portokali.
- Platanitsi: Sand and pristine water below Armenistis — the quieter alternative to Kavourotripes.
- Armenistis: Halkidiki's legendary campsite fronts one of the east coast's best beaches — day visitors welcome.
- Sarti: Three kilometres of sand facing Mount Athos, with full facilities in Sarti village — you always find space.
- Klimataria (Sykia): Organized but laid-back, in the bay of Sykia — beloved by those who want a taverna next to their towel.
The southern tip: Kalamitsi, Porto Koufo, Toroni
- Kalamitsi: Twin sandy coves with transparent water at the village of the same name — also a diving base.
- Porto Koufo: Greece's deepest natural harbour, enclosed by cliffs — fish tavernas by the water. For swimming, prefer the beaches around the bay.
- Toroni: Two kilometres of sand with the ruins of the Lekythos fortress at one end — history and swimming combined, at Toroni village.
- Tristinika: Long, mostly free, with a beach bar at one end — the golden mean between wild and convenient. Next door lies quiet Diaporti with its passage to Pounta islet.
Which beach for whom
- Families with small children: Karydi, Kastri, Livari — see also the shallow-water guide
- Snorkeling: Kavourotripes, Kalamitsi, Tourkolimnionas
- Peace and quiet: Spathies, Diaporti — full list in the quiet beaches guide
- Sunset: Lagomandra and the whole west coast
- Facilities and food by the waves: Sarti, Klimataria, Kastri
Practical notes for Sithonia's beaches
Distances: From Thessaloniki, Nikiti is about 100 km (1h 40m) and Sarti about 130 km (2h+). The loop of the peninsula is ~110 km of coastal road — doable in a day, worth at least three.
Access: The main road is excellent asphalt. Many of the finest beaches, though (Kavourotripes, Spathies, Tourkolimnionas), involve a dirt road or a walk down — passable with care in a regular car.
Parking: At the famous beaches, car parks fill between 11:00-16:00 in July-August. Rule of thumb: before 10:30 or after 17:00.
When: June and September give you the same sea with half the people. September in particular is the regulars' secret — warm water, empty sand, open tavernas.
Boat: In Vourvourou you can rent a licence-free boat (30hp) to circle Diaporos — possibly the best "upgrade" to a beach day in Halkidiki.
Practical notes for international visitors
Sithonia is the choice for travellers who find the packaged side of Halkidiki too smooth: fewer hotel blocks, more nature, legendary campsites. Reckon on 1 hour 45 minutes from SKG airport to Nikiti — the road is well surfaced the whole way.
The insider window is September: the crowds have gone, the sea still holds 24-25°C, and even Karydi feels like a secret again. Come in high summer and the one rule that matters is arriving early — the car parks at the famous coves fill by mid-morning. Fuel up before heading into the southern tip; petrol stations thin out down there.

Based in Nikiti or Sarti, 4-5 days cover the highlights: one for Vourvourou, one for the east coast (Kavourotripes-Platanitsi-Sarti), one for the southern tip (Kalamitsi-Porto Koufo-Toroni) and one for the west coast and its sunset.
Is Sithonia better than Kassandra for beaches?
For natural beauty and variety, yes — which is why most "top beach" lists are dominated by Sithonia. Kassandra wins on infrastructure and nightlife. Full breakdown in the Sithonia vs Kassandra comparison.
