Blue Lagoon (Pisina), Syvota: The Swimming Pool Between Two Islets, Reachable Only by Boat, Where the White Sand Sits Two to Four Metres Below Water That Glows Like It’s Lit From Underneath

Greece | Syvota | Thesprotia, Epirus

Pisina means swimming pool in Greek, and the name was chosen with no exaggeration. The lagoon forms in the narrow channel between the islet of Mourtemeno and the smaller rocky islets just south of it, off the coast near Syvota in Thesprotia. The seabed is white sand, sitting at a depth of two to four metres, and the specific combination of pale sand, direct sunlight, and rock walls sheltering the channel from current produces the colour that gives the place its international nickname: a gradient running from pale aquamarine at the shallow edges to vivid, almost luminous turquoise at the centre, the kind of blue that looks digitally enhanced in photographs until you are actually floating in it.

The shallowness does more than create the colour. It also warms the water a degree or two above the surrounding open sea, and the shelter from the islets means there is no current and essentially no chop — swimming here feels measurably different from swimming in open water nearby, calmer and warmer in a way you notice within the first few strokes. Visibility routinely exceeds fifteen metres. You can watch your own shadow move across the sand beneath you.

There are no permanent buildings on Agios Nikolaos islet or Mourtemeno, and that absence is deliberate rather than an oversight: this is reachable only by water, and the lack of construction is precisely what has kept the lagoon as clear and undisturbed as it remains. The rocky edges of Mourtemeno, where the seabed drops into deeper water on the island’s north side, hold the most marine life — sea bream and wrasse moving between the boulders, visible from the surface given the consistent water clarity.

Getting There: Boat Only — Water Taxi From Syvota Harbour, Self-Rental, or Organised Cruise From Syvota, Parga, or Corfu

There is no road access. From Syvota harbour, water taxis depart roughly hourly, the crossing taking 10 to 15 minutes and costing little. Return boats run similarly often, so a visit can last as long as preferred rather than being fixed to a single round trip.

Renting a small motorboat directly from Syvota — no license required for the smaller craft, typically holding up to four people — is the option that gives the most freedom: arrive early to beat the midday excursion crowds, anchor wherever suits, and explore the wider island complex (Agios Nikolaos, Mourtemeno, and Mavro Oros, the Black Mountain islet with its stone lighthouse and large sea cave) at your own pace. A full day’s rental runs around €70, a half-day around €50.

Organised cruises with glass-bottom boats run daily from both Syvota and Parga, typically including the Blue Lagoon as the primary swimming stop alongside passes by Bella Vraka beach and the sea caves around Mavro Oros. From further afield, day trips by boat from Corfu take approximately 90 minutes each way across the Corfu Strait, combining the crossing with the lagoon swim, a stop in Syvota village, and the return sail. By road, the journey from Athens to the Syvota area via Olympia Odos and the Filippiada-Preveza road takes roughly 5 hours.

The Wider Syvota Islands: Bella Vraka’s Sandbar, Diapori, Alati, and the Caves of Mavro Oros

Bella Vraka, the other beach most visitors to Syvota specifically seek out, has its own remarkable feature: a narrow strip of golden sand that functions as a natural sandbar, allowing visitors to walk directly from the mainland to Mourtemeno islet without a boat at all. Diapori, a quieter cove on Agios Nikolaos islet, and Alati (meaning salt) are the lesser-known beaches that boat renters and more adventurous visitors specifically seek out, away from the regular excursion-boat schedule.

Mavro Oros (“Black Mountain”) sits at the entrance to Syvota harbour alongside Agios Nikolaos, marked by a stone-built lighthouse and a substantial sea cave large enough to be a specific stop on most of the organised boat tours.

Syvota Village and the Mainland Beaches

Back on the mainland, Syvota itself offers Zavia beach near the settlement’s centre (sandy, turquoise, tree-shaded), and further out, Zeri and the sandy white Gallikos Molos (“French Pier”) beaches to the north. Heading toward Perdika, Mikri and Megali Ammos — small and big sand — round out the immediate area’s mainland beach options for visitors who want a day on land between boat excursions to the islands.

Blue Lagoon (Pisina) at Syvota is the swimming-pool channel between Mourtemeno and the smaller islets beside Agios Nikolaos — white sand at 2–4 metres depth, water glowing turquoise to aquamarine, no current and no permanent buildings on either islet, reachable only by water taxi (10–15 minutes from Syvota harbour), self-rental boat (€50–70), or organised cruise from Syvota, Parga, or Corfu (90 minutes by boat). Sea bream and wrasse for snorkelling, visibility regularly exceeding 15 metres, Bella Vraka’s walkable sandbar nearby, Mavro Oros’s lighthouse and sea cave, Diapori and Alati for the boat-renters who go looking, Zavia, Zeri, and Gallikos Molos on the mainland.
