Porto Koufo is located at the southern tip of Sithonia and is something rare in Greece: a natural harbor almost entirely protected from the sea. The bay has an entrance of just 300 meters — from the outside, it is almost invisible. This geographical feature has historically made it a refuge, and it gives its name: "Koufo" from the ancient "kophos" (which cannot be heard), because the waves of the open sea do not reach inside the bay.
The geography that makes it unique
The bay has a bottle shape: a narrow neck at the entrance, a wide interior space. It covers approximately 1.5 square kilometers of water, with depths reaching up to 38 meters. On the eastern side, there is a small settlement with 200-250 permanent residents (perched on a slope), and on the western side, an 800-meter sandy beach stretches out.
Of all the Thermaic-Toroneos Gulf, this is the only place where boats can anchor safely even in strong meltemi winds. That’s why you always see 30-80 boats anchored inside, especially in July-August.
How to get there
Porto Koufo is approximately 150 kilometers from Thessaloniki — that is, a 2 hour and 30 minute drive without traffic. It is at the southernmost point of Sithonia, so if you are coming from the northern side (Nikiti), the route passes through Neos Marmaras → Toroni → Porto Koufo (a total of 25 km from Neos Marmaras). From the eastern side (Sarti), it passes through Sykea and is about 30 km.
There is no direct bus route with KTEL. You must first reach Neos Marmaras or Sarti and continue by taxi (approximately 30-40 euros).
The beach and swimming
The main beach of Porto Koufo is sandy with pebbles in places, and the seabed gradually deepens. Because the bay is closed, the water is almost always calm — even on days when the open sea has waves. This makes it ideal for swimming longer distances, snorkeling, and SUP.
The organization is mild: a few sunbeds near the taverns, mostly a free beach. It does not have the intense "beach bar" culture of Sarti or Kallithea. Many people appreciate this — it has a more thoughtful, less party-like character.
For snorkeling, the best spots are at the rocky edges of the bay (near the entrance), where you can see bream, salouvarides, and octopuses. The visibility is among the best in Sithonia due to the bay's protection.
Possibly the best fish tavern in Sithonia
Porto Koufo is famous for its seafood. Not because it is a "secret" — simply because the fish come straight from the boats to the taverns, at distances of 20-50 meters. There are several traditional fish taverns right on the water, and the fish are weighed in front of you. Fish prices: depending on the type and season, from 45-70 euros/kg for common sizes, up to 100+ for grouper, dentex.
What’s worth asking for: gobies or sardines (fresh every day, affordable, 12-16 euros per serving), grilled red mullet, grilled octopus. If in season, live Symonian shrimp.
Accommodation — fewer but good options
Porto Koufo is not a "hotel" place. It has only a few small accommodations, mainly family-run studios and apartments. Two relatively larger options: the Porto Carras affiliate hotel and one or two boutique accommodations on the slopes above the bay with a view.
Indicative prices:
- Studio for 2 people: 60-90 euros/night in June/September, 90-140 in peak
- Apartment for 4 people: 100-160 in normal, 150-220 in peak
Due to limited capacity, bookings 3+ months in advance for peak season are necessary.
Many use Porto Koufo as a day trip from Sarti or Neos Marmaras instead of staying there. This works well — you can leave in the morning from your base, arrive by 11:00, swim, have lunch with fish, and return in the afternoon.
What else can you do
- Hiking to the cape: a path from the village to the southern tip of the peninsula, duration 1-1.5 hours, with spectacular views of the Aegean. On clear days, you can see as far as Athos and Samothrace.
- Kayaking or SUP in the bay: safer water than anywhere else in Sithonia. Rentals are available from kiosks on the beach, 10-15 euros/hour.
- Scuba diving: 1-2 dive centers in the wider Sithonia conduct dives in the bay. There are wrecks of small boats and rocky areas rich in life.
- Sunset cruise: small boats offer 2-hour evening trips outside the bay for the sunset — from the open sea, the view of Porto Koufo and Sithonia is stunning.
A bit of history
Porto Koufo is mentioned by Thucydides as a refuge for the ancient Athenian fleets. They called it "Kophos Limen" — meaning deaf, silent harbor, because the waves cannot be heard inside. During World War II, the Germans used it as a submarine naval base, taking advantage of its natural security. Some remnants from that period (concrete structures on the slopes) are still visible if you walk towards the cape.
When to go
Like throughout Halkidiki, June or September offer the best experience. In Porto Koufo specifically, August can be crowded because the harbor fills with boats and the small infrastructure at the taverns gets strained. Always make a reservation for a table in advance.
In winter, almost everything closes — only 1-2 taverns and a couple of cafes operate for locals and some boats that winter there.
