Northern Sporades — A Gentle Aegean Escape
A chain of emerald islands rising from deep blue water in the north-west Aegean, beyond Evia. Short passages, clear navigation, deep water close to shore, and Greece’s most successful Marine Park. The Aegean as families sail it best.
In the north-western Aegean, just beyond Evia, lies a cruising area that breaks the Greek-island stereotype. The Northern Sporades are greener, gentler, and less wind-battered than the Cyclades — pine-covered hills tumbling to clear bays, sheltered straits between four main islands, and the Aegean’s first national marine park stretching north to the protected Mediterranean monk-seal habitat.
For sailors, this is one of Greece’s most inviting regions: short passages, clear navigation, deep water close to shore, and a relaxed rhythm that suits family cruising. Where the Cyclades demand experience, the Sporades reward planning. Where Saronic feels like a charter highway, the Sporades feel like a private corner of the Aegean.
This is the SeaTV regional hub for the Northern Sporades. Every island, anchorage, and route on the page links to a dedicated SeaTV page with full mooring detail, hazards, and shore information.
⚠ Reality check before you sail the Sporades:
→ Marine Park permit required for sailing in the Alonissos National Park area
→ Deep water close to shore — anchoring scope and slope-aware setting essential
→ Reefs near outer islets — Gioura, Psathoura, Skantzoura need care
→ Shallow areas west of Skiathos require attention on approach
→ Northerlies build through afternoon — choose south-facing bays for overnight

Four Islands, One Gentle Cruising Rhythm
The Northern Sporades chain stretches east-north-east from Evia. Most 7-day charters focus on the inner triangle of Skiathos, Skopelos, and Alonissos — Skyros is reached only on longer trips.
Skiathos · Western Sporades · Charter Gateway
Skiathos
Character: The main gateway and liveliest island. Naturally protected harbour, international airport, the busiest of the four. Famous for pine-fringed beaches and a working old-town front.
Best for: Charter starts and finishes, crew rotations, last-night dinners.
⚠ Watch: Shallow areas west of Skiathos require attention on approach.
Skopelos · Central Sporades · Greenest Island
Skopelos
Character: Greener and quieter than Skiathos. Forested hills, pristine bays, the famous chapel of Agios Ioannis (Mamma Mia! church) on the east coast.
Best for: The middle of a Sporades week — relaxed bays, walkable old town in Skopelos Chora.
Alonissos · Eastern Sporades · Marine Park Gateway
Alonissos
Character: The most pristine of the four — long thin island with the National Marine Park stretching north of it. Protected nature, quieter anchorages, fewer charter crowds.
Best for: Marine Park access (with permit), nature-focused cruising, evenings without the crowd.
Skyros · South-East Sporades · Long Passage
Skyros
Character: More remote than the other three — fortified hilltop town, distinctive rural traditions, a separate breed of small Skyrian horses.
Best for: Two-week charters or experienced crews willing to plan a longer passage. Typically outside a standard 7-day family itinerary.
A Simple Family Route — Skiathos · Skopelos · Alonissos
Most family-friendly itineraries focus on the inner triangle: Skiathos → Skopelos → Alonissos. The islands sit close together, so even when the breeze builds, you can keep passage times short and arrival times early.
Depart from Skiathos and, within minutes, the coastline turns to green slopes and clean blue depth. Cross to Skopelos over a calm strait, then continue toward Alonissos on another gentle passage. These are classic Aegean days: straightforward navigation, beautiful light, and easy decisions.
SeaTV’s recommended Sporades itinerary covers Volos → Skopelos → Marine Reserve → Alonissos → return — 7 days, day-by-day breakdown, with lessons from the storm-driven return that taught us why the southern bays matter.
Winds in Summer — What to Expect (Without the Drama)
In summer, prevailing winds are typically northerly (N–NE), influenced by the Meltemi pattern. In the Sporades, winds are often perceived as more manageable than in more exposed island groups — the high, green terrain softens conditions near shore, and the shorter fetch keeps wave heights down compared to the open Aegean.
A practical daily rhythm
Mornings: often calmer — ideal for easy departures and relaxed family routines.
Midday–afternoon: a steadier breeze builds — great for a pleasant sail without long crossings.
Shelter plan: when northerlies increase, southern bays offer comfortable protection.
Family crew tip: Keep legs short, arrive early, and choose south-facing bays when northerlies are up. This keeps the experience smooth and enjoyable without limiting exploration.
Depths, Seabed & Coastal Structure
A defining feature of the Sporades is deep water close to shore — especially along northern and eastern coasts. The seabed often drops quickly, and many anchorages are clear with good holding when you choose sand or sand/weed mix.
What this means for skippers
→ Rapid drop-offs: plan your approach and anchor set with the slope in mind
→ Typical anchoring depths: often around 5–12 m (spot-dependent)
→ Scope awareness: important due to gradients and depth changes close to shore
→ Deep-draft friendly: main straits between the primary islands are commonly transited
⚓ Sheltered Bays & Overnight Stops
When northerlies blow, the most comfortable overnights are often found on southern coasts. Below are well-known options frequently used by cruising yachts (always confirm with current charts, pilotage notes, and local guidance).
Skiathos
Skiathos South Coast Anchorage
Koukounaries (south coast): Popular and sheltered in northerly patterns. Pine-fringed beach, walkable shore, classic Sporades anchorage atmosphere.
Skopelos
Skopelos · 3 Main Anchorages
Panormos (SW coast): Comfortable overnight option with good shelter from northerlies.
Agnontas (south coast): Commonly used for shelter, small village ashore.
Loutraki (NW): Port option depending on plan and conditions.
→ Full detail: Skopelos best Anchorages & Bays
Alonissos
Alonissos · Port + Bay
Patitiri (SE): The main port and services hub of Alonissos. Year-round small fishing fleet, ferry connection, supermarkets, restaurants.
Mourtia (south): Often a good choice with N/NE winds — quiet, scenic, away from the port crowds.
Marine Park access: From Patitiri, head north into the protected zone — see Kyra Panagia & the Marine Park.
Outer Islets — Day Visits, Not Overnight
Islets such as Gioura, Psathoura, and Skantzoura are scenic and dramatic, but generally more limited for comfortable overnight anchoring. Many crews prefer day visits and return to the better-sheltered bays. Charted reefs require care on approach to all three.
The Alonissos Marine Park — Greece’s First
The National Marine Park of Alonissos and the Northern Sporades was established in 1992 — the first marine park in Greece, and one of the largest protected marine areas in Europe. The park covers the waters and small islets north and east of Alonissos, protecting the habitat of the endangered Mediterranean monk seal (Monachus monachus).
For sailors: The park is split into Zones A and B. Zone B allows controlled sailing access; Zone A is restricted. A permit is required for sailing within the park boundaries — secured in advance via charter company or Alonissos port authority.
Best anchor in the park: Kyra Panagia — a sheltered bay with sand bottom, working monastery on the island, dramatic cliff scenery. The single most photogenic stop in the Sporades. Full mooring detail on the Kyra Panagia Marine Park page.
Skipper Briefing — Distances & Navigation
Distances (approximate ranges)
→ Skiathos → Skopelos: approximately 12–15 NM
→ Skopelos → Alonissos: approximately 10–18 NM
→ Alonissos → Kyra Panagia (Marine Park area): approximately 10–16 NM
These moderate legs allow early departures and flexible daily routing — especially useful for family crews.
Navigation notes
→ Main passages between Skiathos, Skopelos, and Alonissos are straightforward with clear visual navigation
→ Maintain awareness of charted reefs near outer islets (Gioura, Psathoura, Skantzoura) and around south-west Skopelos
→ Shallow areas west of Skiathos require attention
→ Night navigation is possible with standard caution; several navigational lights assist approaches
→ Traffic is generally moderate; main commercial routes pass further west toward Thessaloniki
Charter Base Options
Volos · Mainland Charter Hub
Volos (Mainland)
Position: Mainland port at the head of the Pagasitic Gulf, ~3–4 hours by road from Athens.
Use: Major Sporades charter base · convenient if combining a Sporades week with a Pelion peninsula land-trip.
First-day passage: Volos → Skopelos is the natural first leg (~30 NM south-east).
Skiathos Town · Island Charter Base
Skiathos
Position: Skiathos Town harbour, the most-developed harbour in the chain.
Use: Smaller charter operations · suitable for crews flying directly into Skiathos International Airport.
First-day passage: Often shorter — straight east to Skopelos (~12–15 NM).
Athens (Lavrion / Olympic) · Long Repositioning
From Athens (Two-Week Trips)
Crews based in Athens (Lavrion / Olympic / Alimos) can reach the Sporades on a longer passage — typically 120 NM north — but this only makes sense for 2-week charters. See the Athens charter base overview.
When to Sail the Sporades
May–June: The ideal window. Stable weather, fewer charter crowds, comfortable temperatures, Meltemi just starting. Pine forests at their freshest.
July–August: Peak season — busy but still manageable. The Sporades version of the Meltemi rarely reaches the Cyclades intensity. Family-friendly even in high summer.
September–October: Strong shoulder season. Meltemi easing, water still warm, evenings golden. SeaTV’s frequent recommendation for relaxed crews.
November–April: Off-season. Some marinas reduce services, frontal weather systems possible. Not for charter weeks.
SeaTV’s Top Tips for the Sporades
Secure the Marine Park permit before you sail. The permit takes a couple of days; don’t leave it for arrival day at Patitiri. Charter companies usually handle this if you tell them the trip plan up front.
Plan southern bays for nights, northern coasts for days. The pattern is consistent: morning calm, building afternoon northerly. South-facing anchorages give the comfortable overnight; northern coasts are spectacular but rougher after midday.
Slope-aware anchoring. Deep water close to shore means rapid drop-offs. Drop near the slope, set hard, watch the chain angle, don’t rely on rules-of-thumb from shallow flat-bottom anchorages.
Time the storm contingency. When weather builds, the safest move is back to a marina-grade harbour — Skiathos Town or Patitiri (Alonissos). Don’t wait until dusk to make the call.
Day-trip to Kyra Panagia. Even if you can’t overnight in the park, a day visit to Kyra Panagia (return to Patitiri or a southern Alonissos bay before evening) is one of the highlights of a Sporades week. Working monastery, dramatic cliffs, clear water.
Mamma Mia! church on Skopelos. The cliff-top chapel of Agios Ioannis on the east coast. Worth a brief anchor stop and a shore walk up the steps if conditions allow.
Volos for repositioning. If your charter is one-way Skiathos to Volos (or vice-versa), the legs work well — Volos is 3–4 hours by road from Athens, useful for crews wanting to combine sailing with a Pelion peninsula stop.
⚠ Sporades Hazard Summary
Marine Park boundaries: Permit required for entry · plot Zone A vs Zone B before sailing
West Skiathos shallows: Charted shallow areas require attention on approach from the west
Outer islets reefs: Charted reefs around Gioura, Psathoura, Skantzoura
