Hydra Sailing Guide: Anchorages, Harbours and Tips

Updated: September 2026

For sailors exploring the Argo-Saronic Gulf, Hydra is primarily a destination for its world-famous harbour town, whose unique architecture, maritime heritage, and vehicle-free atmosphere make it one of the most iconic stops in Greece.

Overview

Hydra (Ύδρα) is one of the most distinctive islands in Greece, famous for its elegant stone mansions, wealthy maritime past, and complete absence of motor vehicles. The island played a central role during the Greek War of Independence and remains one of the most iconic destinations in the Argo-Saronic Gulf.

For sailors, Hydra presents a unique contrast. The harbour of Hydra Town is one of the most desirable destinations in Greece, yet also one of the most difficult places to secure a berth. Fortunately, the island is surrounded by excellent anchorages that allow easy access to the town while offering a far more relaxed experience.

Sailing Conditions in Hydra

Hydra lies near the boundary between the Saronic and Argolic Gulfs and is partially sheltered from the prevailing summer northerlies by the Peloponnese coast to the north.

  • Prevailing wind: N to NW during summer
  • Mornings: usually light winds
  • Afternoons: moderate northerlies, occasionally strong
  • Evenings: winds typically ease

The northern coast provides excellent shelter from southerlies, while southern anchorages are well protected from northerlies.

Katabatic gusts can occur in several bays due to Hydra’s steep terrain, particularly during stronger northerly weather.

If you’re looking for the best anchorages in Hydra, here is a quick overview:

General rules:

  • Use Mandraki or Molos when visiting Hydra Town.
  • Explore the western coast for quieter overnight stops.

Planning Your Sailing Trip to Hydra

Hydra is one of the busiest islands in the Argo-Saronic Gulf during summer.

Before visiting:

  • Assume that a berth will not be available in Hydra Harbour.
  • Arrive early if attempting to dock in town.
  • Carry sufficient chain, as many anchorages are relatively deep.
  • Expect stern lines ashore to be the preferred technique in several bays.
  • Keep a list of local sea-taxi operators.
  • Book restaurants early during peak season.

Many sailors consider Hydra Town the highlight of a Argo-Saronic cruise, but securing a berth there is a great challenge.

Sea Taxis

As cars are not allowed on Hydra, sea taxis are a common means of transportation between Hydra Town, nearby beaches, and anchorages. The list below provides contact information for local operators.

Locations

Hydra Town

Type: Historic harbour town
Best for: Sightseeing, restaurants, atmosphere

Hydra Town is one of the most famous destinations in Greece and one of the highlights of any cruise in the Argo-Saronic Gulf. Built amphitheatrically around a horseshoe-shaped harbour, it is renowned for its elegant stone mansions, narrow alleys, maritime history, and unique character. The town played a major role during the Greek War of Independence, when Hydra’s powerful merchant fleet helped finance and support the Greek cause.

What makes Hydra truly special is the absence of vehicles. Cars, motorcycles, scooters, and even bicycles are prohibited, with transportation provided on foot, by donkey, or by boat.

The town offers:

  • Excellent restaurants and cafés.
  • Boutique shops and art galleries.
  • Small supermarkets and bakeries.
  • Historical museums.
  • Water taxis to beaches and nearby anchorages.

Visiting Hydra Town

Popular activities ashore include:

  • Walking through the maze of stone-paved alleys.
  • Visiting the Historical Archives Museum of Hydra.
  • Exploring the mansions of the island’s shipping families.
  • Climbing to the viewpoints west of the harbour.
  • Swimming from Spilia and Hydroneta. The sunset from there is amazing.
  • Walking to Kaminia and Vlychos along the coastal path.
  • Watching the constant harbour activity from one of the waterfront cafés.

The harbour itself is one of the island’s most impressive attractions, lined with restaurants, shops, and historic buildings. The entire waterfront remains lively from early morning until late evening.

Don’t miss the opportunity to wander through the town’s picturesque alleyways. Among the many tavernas, Xeri Elia – Douskos, a favourite of Leonard Cohen, is well worth a visit.

Docking

Hydra Harbour

Protection: Excellent
Holding: Excellent in mud
Characteristic: Extremely crowded

Entrance. Pos.: 37°21.062′ N, 23°27.982′ E

Hydra Harbour is one of the most challenging places to berth in Greece. My recommendation, and what most professional skippers do, is anchoring in Mandraki or Molos, and visiting Hydra Town with a sea-taxi.

Mooring
  • Check the Hydra Harbour Map below for available berths.
  • Stern-to quay with anchor.
  • Second, third, or even fourth rows of yachts are common during peak season.

⚠️ Important:

  • Arrive as early as possible, preferably before 09:00 during summer.
  • Prepare to wait in line in the harbour’s entrance for departing yachts to leave.
  • In summer, securing the place of a yacht that has just departed is often the only way to find a berth.
  • Large areas are reserved for ferries, water taxis, excursion boats, fishing vessels, and commercial traffic.
  • Harbour traffic is intense throughout the day.
  • The harbour bottom contains hundreds of crossed anchor chains.
  • Several permanent chains and cables cross parts of the harbour.
  • Anchor fouling is extremely common.
  • Boats leave in sequence during the morning to avoid anchor entanglement. The system is First In Last Out.
  • Always check the angle of neighbouring anchors before dropping your own.

Conditions
  • The harbour provides excellent protection from the wind.
  • Frequent wash from ferries and sea-taxis.
  • Harbour manoeuvres are often complicated by congestion.
Facilities
  • No electricity supply.
  • Water is supplied by tanker truck at the quay.
  • No organised marina facilities.
  • No mooring assistance.

Overall

Hydra Town is one of the most beautiful and iconic destinations in Greece and is considered a must-visit by most sailors. Consider visiting from a nearby anchorage to avoid the chaos in its harbour.

For many sailors, Hydra is a place to visit at least once. The harbour can be chaotic, but few destinations in the Argo-Saronic Gulf match its atmosphere, beauty, and historical significance.

Mandraki Bay

Type: Bay anchorage
Best for: Visiting Hydra Town, shelter, overnight stays

Mandraki (Μανδράκι) is the most popular anchorage near Hydra Town and the preferred alternative when the harbour is full—which, during summer, is most of the time. Located about a mile east of Hydra Town, it combines good protection, easy access to town, and enough space for a large number of yachts.

The bay is home to a beach resort, restaurant, beach bar, and a popular beach. It can be busy during the day, but conditions become noticeably quieter after sunset. Sea urchins are common along the shoreline.

For many skippers, Mandraki is the best way to experience Hydra. It avoids the congestion, crossed anchors, and long waits associated with Hydra Harbour, while remaining within easy reach of the town. Hydra Town can be reached:

  • On foot in approximately 20–25 minutes.
  • By water taxi in about 5 minutes.

Sea taxis operate 24 hours a day and provide easy access to Hydra Town. The typical fare is around €30 per boat each way. For contact information, see the Sea Taxis contact list.

⚓ Anchoring

How to Anchor

The bay is deep, with depths increasing rapidly towards the centre. Anchor near the edges and secure stern lines ashore.

  • Stern Lines: Commonly used on both sides of the bay to keep the anchor chain in shallower water. The windward shore is always the preferable option.
  • Crowding: Arriving before mid-afternoon improves the chances of securing a good position during summer.
  • Katabatics: Occasional afternoon downslope gusts descend from the surrounding hills.
  • Wake: Frequent water taxi traffic generates some daytime movement.
  • Dinghy Landing: At the rocks where stern lines are secured, or at the resort jetty.

⚠️ Anchoring Hazard

Particular care is required in the area around 37°21.289′ N, 23°28.988′ E, near the large blue vessel where numerous anchors have become trapped in abandoned moorings. Diver assistance to recover fouled anchors, costs around €400. Using a trip line can significantly improve the chances of recovering a fouled anchor..

Agios Nikolaos Bay

Type: Bay anchorage
Best for: Seclusion, swimming, shelter from northerlies

Agios Nikolaos (Άγιος Νικόλαος – Saint Nicholas) is a beautiful bay on the southwest coast of Hydra, offering a much quieter alternative to the crowded anchorages near Hydra Town. Surrounded by steep hills and pine-covered slopes, it combines clear water, good protection, and a distinctly remote atmosphere. Even when conditions outside are uncomfortable, the bay often remains relatively sheltered. Water clarity is excellent, making it ideal for swimming and snorkelling, while the rocky edges of the bay attract abundant fish life.

The bay can only be reached by boat or a hiking trail. A pebble beach occupies the head of the bay, while a beach bar operates during summer. During the day, visitors arrive by sea taxi, but the bay becomes remarkably peaceful once they depart in the late afternoon.

Mobile phone coverage can occasionally be limited.

⚓ Anchoring

How to Anchor

Free anchoring is possible near the centre of the bay, while stern lines are commonly run ashore along the eastern side.

  • Shoreline: Rocks near the shore can be sharp and slippery when handling lines.
  • Katabatics: Strong downslope gusts can occasionally descend from the surrounding hills, especially during strong northerlies.
  • Wind Shifts: Wind direction may vary considerably within the bay.
  • Dinghy Landing: Easy on the pebble beach.

Mpisti Bay

Type: Bay anchorage
Best for: Seclusion, swimming, overnight stays

Mpisti Bay (Μπίστι) lies on the southwestern side of Hydra and offers a quieter alternative to the island’s better-known anchorages. Surrounded by rugged hills and clear blue water, it has a distinctly wild atmosphere and usually attracts fewer boats than Mandraki or Molos.

The bay is particularly appealing to crews looking for peace and quiet, excellent swimming, shelter from northerlies, and a more natural setting away from Hydra Town. Mobile phone coverage may be weak.

⚓ Anchoring

  • Approx. Pos.: 37°17.904′ N, 23°22.106′ E
  • Protection: Good except W
  • Seabed: Sand, rock, and extensive patches of posidonia.
  • Holding: Fair to good when anchored in sand
  • Depths: 8–10 metres
How to Anchor

Free anchoring is possible in the central part of the bay, while stern lines are commonly run to the northern and southern shores. The northern shore generally provides the better stern-line positions in the prevailing northerlies.

  • Rocks: Large areas of rock and posidonia reduce holding, and anchors can become trapped beneath rock ledges or between slabs.
  • Swell: Stronger northwesterlies or westerlies can introduce swell into the bay.
  • Wind Shifts: Wind may funnel and rotate within the bay, causing boats without stern lines to swing significantly.

Agios Georgios

Type: Small bay anchorage
Best for: Seclusion, swimming, overnight stays

Agios Georgios (Άγιος Γεώργιος – Saint George) is a small and attractive anchorage on the southern side of Hydra, easily recognised by the tiny chapel overlooking the bay. Surrounded by pine trees and steep hillsides, it is one of the island’s most picturesque anchorages and offers a distinctly remote atmosphere.

The bay is relatively small and typically accommodates only a handful of yachts, making it particularly appealing to crews seeking peace and quiet away from the busier parts of Hydra. Crystal-clear water, abundant fish life, and beautiful sunsets further add to its appeal.

⚓ Anchoring

  • Approx. Pos.: 37°18.238′ N, 23°22.551′ E
  • Protection: Good from S, exposed to N
  • Seabed: Sand with patches of posidonia.
  • Holding: Good in sand. Avoid posidonia patches
  • Depths: 8–12 metres
How to Anchor

Free anchoring is possible in settled conditions, but most yachts use stern lines ashore due to the limited swinging room.

  • Space: The bay is small and can accommodate only a limited number of yachts.
  • Shore Attachments: Large rocks and trees provide suitable attachment points for stern lines.
  • Wind: Gusts may occasionally descend from the surrounding hills.
  • Traffic: The bay can become busy with visiting boats during the day.
  • Ashore: A footpath leads to the tiny chapel of Agios Georgios overlooking the anchorage.

Bali Cove

Type: Small cove anchorage
Best for: Quiet overnight stays, swimming, seclusion

Bali Cove (Μπαλί), on the northwestern side of Hydra opposite Petassi Islet, is one of the island’s lesser-known anchorages. With clear water, a small beach, and steep rocky shores, it offers a peaceful alternative to the busier bays closer to Hydra Town.

Its limited capacity and secluded setting make it particularly attractive to crews seeking tranquillity and a more natural atmosphere. Excellent water clarity and good snorkelling along the rocky sides of the cove add to its appeal.

The surrounding headlands help reduce swell from most directions, and conditions are usually calm after sunset.

⚓ Anchoring

  • Approx. Pos.: 37°18.769′ N, 23°22.828′ E
  • Protection: Good from N–E–S, exposed to W
  • Seabed: Sand with patches of weed.
  • Holding: Good in sand
  • Depths: 5–12 metres
How to Anchor

Use stern lines ashore due to the limited space available. Suitable attachment points can be found on both sides of the cove.

  • Space: Limited to approximately 2–4 yachts. The anchorage fills quickly during busy periods.
  • Swell: Westerlies can introduce swell into the cove.

Molos Bay

Type: Bay anchorage
Best for: Quiet overnight stays, visiting Hydra

Molos Bay (Μόλος) is a peaceful anchorage west of Hydra Town and one of the island’s best alternatives to the crowded harbour. While it lacks shoreside facilities, it compensates with good anchoring depths, clear water, tranquillity, and generally fewer boats than Mandraki.

The bay is particularly popular with sailors looking to avoid the congestion of Hydra Harbour, the deep-water anchoring of Mandraki, and the bustle of the more frequented anchorages. Although much of the shoreline is occupied by a large private villa, this has little practical impact on visiting yachts.

The bay becomes very quiet after sunset. Water clarity is good and suitable for swimming, although sea urchins are present along parts of the shoreline.

⚓ Anchoring

How to Anchor

Free anchoring is possible in the centre of the bay, but stern lines are recommended during busy periods. Lines can be run to either side of the bay, although the windward shore is always the preferred choice.

  • Space: The bay can become busy during summer afternoons.
  • Swell: Some ferry wash and sea taxi wake may enter during the day, but nights are usually calm.
  • Dinghy Landing: There are no public landing facilities. The piers, staircases, and shoreline access points are private.
  • Access to Hydra Town: By sea taxi. The typical fare is around €60 per boat each way. For contact information, see the Sea Taxis contact list.

⚠️ Anchoring Hazards

The bay contains numerous underwater obstructions, including old anchors, heavy chains and concrete blocks. Use a trip line to facilitate anchor retrieval if your anchor becomes fouled. Particular caution is required around the pier area.
