Tselevinia Sailing Guide: Anchorages & Tips

Updated: September 2026

The Tselevinia Islets are a small group of uninhabited islets south of Poros, offering some of the clearest waters in the area and a welcome escape from the busier anchorages around Poros Town.

Overview

The Tselevinia Islets, from west to east, are Gali, Spathi, and Skyli. They are located right where the Saronic and Argolic Gulfs meet.

The two main anchorages in the group are located south of Skyli Islet and north of Gali Islet, both suitable for swimming stops and peaceful overnights in settled weather.

Skyli Islet is the quieter and more secluded of the two. It offers good holding in sand, excellent snorkelling, and attractive scenery, although it is more exposed to swell and passing boat wash.

The Gali Islet anchorage is larger and better protected from northerly winds. Its crystal-clear water, sandy seabed, and small beaches make it one of the most popular swimming anchorages in the area. Despite attracting numerous day visitors during summer, it usually becomes quiet again in the evening.

Both anchorages require careful anchor placement among patches of posidonia and provide a distinctly remote island atmosphere despite being only a short distance from Poros and the Peloponnese coast.

⚠️ Attention: The channel northeast of Gali Islet, between the Peloponnese coast and Spathi Islet, is shallow. Depths are less than 1 metre.

The channel between Spathi Islet and Skyli Islet has depths of approximately 20 metres and provides safe passage. Note that winds from both the north and south tend to funnel through the channel.

Locations

Skyli Islet

Type: Cove anchorage
Best for: Lunch stop, snorkelling, secluded overnight stays

This small cove on the southern side of Skyli Islet (Σκυλί) is a quiet and scenic anchorage in the Tselevinia group, primarily used as a lunch stop or overnight anchorage in settled conditions. The setting is natural and unspoilt, with crystal-clear water, good snorkelling, and very little development. Outside peak periods, it is common to have only a few boats nearby.

⚓ Anchoring

  • Approx. Pos.: 37°26.334′ N, 23°32.502′ E
  • Protection: Limited; best in calm weather or light northerlies, exposed to S
  • Holding: Good in sand with weed patches. Carefully select sand when dropping anchor.
  • Depths: 5–7 metres
How to Anchor

Free anchoring is possible in the sandy areas of the cove. Commonly, stern lines are used to the northeastern shore.

  • Entrance Hazard: A reef and scattered rocks extend from the eastern side of the entrance to approximately 37°26.164′ N, 23°32.592′ E.
  • Swell: Southerlies and passing boat traffic can make the anchorage rolly.
  • Strong Winds: In strong northerlies, gusts funnel through the cove and reduce comfort.
  • Southerlies: In southerly conditions, the northern cove around 37°26.463′ N, 23°32.334′ E is the better option.

Gali Islet

Type: Cove anchorage
Best for: Swimming, snorkelling, overnight shelter in northerlies

Gali Islet (Γαλή) offers the most attractive anchorage in the Tselevinia group, renowned for its crystal-clear turquoise water, excellent visibility and abundant fish life. While it can be busy during the day, nights are usually quiet and peaceful. Mobile phone and internet coverage may be limited.

⚓ Anchoring

  • Approx. Pos.: 37°26.045′ N, 23°31.184′ E
  • Protection: Good from N–NW, moderate from E
  • Seabed: Sand with patches of posidonia.
  • Holding: Good in sand
  • Depths: 4–8 metres
How to Anchor

Anchor freely in the sandy areas between the patches of posidonia. Optionally run stern lines along the Peloponnese coast north and northwest of Gali Islet

  • Swell: Some swell may enter from the southeast, while ferry and boat wake can affect the anchorage during the day.
  • Ashore: A footpath starting from the small beach at 37°25.920′ N, 23°30.979′ E leads to the small chapel of Panagia (Παναγία) overlooking the anchorage.
