Why Sail in Uppland (Roslagen & Öregrund Archipelago)?

Uppland is the northern reach of the Stockholm archipelago—known locally as Roslagen—extending to the old pilot towns of Östhammar and Öregrund. For sailors, this coastline is a fine balance: extensive sheltered waters for stress-free passages on breezier days, and quick access to the more exposed Åland Sea when you want longer, open-water legs. The sailing day can be as short or as ambitious as you wish, and you are rarely more than an hour from a bolt‑hole.

The character of the place is unmistakably Nordic. Granite ledges warmed by the afternoon sun invite a classic Swedish stern‑to‑rock moor. Small red‑painted harbours offer fuel, fresh cinnamon buns and hot showers. Out among the outer skerries—Norrpada, Fejan and the Arholma group—the horizon opens and the water deepens, but navigation remains precise and satisfying.

Accessibility adds to the appeal. Arlanda Airport sits within the province; Norrtälje, Furusund and Kapellskär are an easy transfer away, and ferries link nearby Grisslehamn and Kapellskär with Åland and Finland. Spend a week here and you will stitch together quiet anchorages, lively harbour evenings and memorable sunsets that barely dip below the treeline at midsummer.

Itineraries

Below are two tried‑and‑tested routes that blend sheltered inner fairways with forays to the outer skerries. Distances are moderate, pilotage is engaging, and there are options to shorten or extend most days depending on wind and crew energy.

7-day Roslagen to Öregrund circuit (moderate, mix of sheltered and coastal legs)

A 7-day route. Adjust legs to forecast, moorings and crew preferences.

Day 1 — Norrtälje to Furusund (inner fairways)

A gentle shakedown along marked inner routes via Norrtäljeviken and Blidöfjärden. Expect flat water, frequent marks and occasional ferry traffic near Räfsnäs and Kapellskär fairways. Settle the crew, run through MOB and mooring drills, and arrive early for a relaxed first evening ashore.

Harbour options are straightforward: start from Norrtälje Gästhamn and aim for guest berths at Furusund. Keep an ear on VHF and give commercial ferries ample room when crossing the Kapellskär fairway.

Day 2 — Furusund to Arholma

Run north past Blidö and across open reaches to Arholma. The outer skerries begin to show; navigation remains well marked but keep a sharp eye for off‑lying rocks. In settled weather, a lunch stop at Granhamn is rewarding.

Approaches to Arholma are clear with leading lines. Berths fill on peak summer weekends—arrive mid‑afternoon if possible.

Day 3 — Arholma to Fejan/Norrpada (outer skerries)

Short outer‑archipelago hop. Pick a natural granite cove in Norrpada or take a berth at Fejan’s guest harbour. Classic Swedish stern‑to‑rock mooring with shorelines is the order of the day; choose a notch with protection from the forecast sector.

If you prefer facilities, Fejan offers a friendly harbour and a café in season; otherwise, Norrpada’s coves are perfect for swimming and evening walks.

Day 4 — Fejan/Norrpada to Grisslehamn or Singö

Edge northwest along the outer coast towards Grisslehamn. Time your departure to avoid stronger afternoon sea‑breezes if heading outside. Alternatively, shelter behind Singö’s inner waters for a quieter, more protected route.

Grisslehamn is convenient but can be lively with ferry movements; if northerlies are fresh, the inner option via Singö is appreciably calmer.

Day 5 — Grisslehamn/Singö to Öregrund (coastal leg)

A longer day along the Uppland outer coast towards the historic pilot town of Öregrund. Keep outside dangers well identified; conditions build quickly with northerlies over the Åland Sea, creating a short, steep chop.

The Gräsö South Fairway provides a clear approach; once inside, enjoy the contrast of sheltered waters after the coastal leg.

Day 6 — Öregrund to Östhammar via Gräsö channel

Sheltered pilotage south through the narrows between Gräsö and the mainland. Mind speed limits and local traffic. Östhammar offers a friendly guest harbour close to cafés and stores—ideal for a leisurely layover and resupply.

Expect picturesque, low‑stress sailing with regular marks and calm water—perfect for less experienced crew to helm.

Day 7 — Östhammar to Norrtälje (inner route)

Return through protected waters. Expect narrow sounds, occasional bridges and marked speed‑restricted sections. This is a relaxed final leg back to Norrtälje; aim to arrive with time for a stroll through the old town before check‑in.

As always in the skerries, resist the urge to “cut corners”; stay on the leading lines and keep speed down where depths shelve near rocks.

4-day Outer Roslagen taster (short hops, scenic skerries)

A 4-day route. Adjust legs to forecast, moorings and crew preferences.

Day 1 — Norrtälje to Blidö

An easy inner‑fairway run to settle the crew. Blidö offers several inviting coves and small jetties. Keep a lookout for local ferries and respect speed‑limited stretches.

In fine weather, an evening stern‑to moor on smooth granite is a memorable introduction to Swedish archipelago life.

Day 2 — Blidö to Rödlöga

Head east across open water to Rödlöga, a classic outer‑archipelago island with a small shop and summer bustle. Good stern‑to‑rock options in settled weather; in fresher winds, choose a more tucked‑in notch or arrive earlier for a buoy.

Allow time ashore—paths weave between red cottages and rocky viewpoints.

Day 3 — Rödlöga to Fejan via Norrpada

Short, scenic sailing among skerries. Stop for lunch on a buoy or in a granite notch in Norrpada before continuing to Fejan’s guest harbour. Pilotage is straightforward with close attention to marks and sectors.

Fejan provides welcome facilities and a convivial evening spot to swap stories with other crews.

Day 4 — Fejan to Norrtälje via Furusund

Run back inside via well‑marked channels. Watch for ferry traffic near Räfsnäs and Kapellskär. If time allows, pause in Furusund for a mid‑sail coffee before the final leg to Norrtälje.

This route is ideal as a long weekend or a gentle sampler before a longer circuit later in the season.

When to go

The season runs from late May to early September. June brings long daylight and quieter harbours before schools break up; Midsummer weekend is busy and festive. July and early August are peak season with the widest opening hours for shops, restaurants and fuel docks. Late August to early September is often settled, with warmer seas and fewer crowds.

Sea temperatures typically reach 16–20 °C in high summer. Inner waters warm first, while the Åland Sea stays cooler. Expect very long days from late May through July—near‑continuous twilight at midsummer—making early starts and late arrivals practical if needed. Nights in May and early June can still feel cool aboard; light heating is welcome on smaller yachts.

Fog can occur in late spring and early summer when warm air passes over cold water. Ice persists in inner bays through winter; most local sailing does not resume until May. Occasional algal blooms may appear in high summer; avoid swimming when water clarity is visibly reduced.

Wind and weather

Prevailing synoptic winds in summer are south‑westerly to westerly at a gentle to moderate strength. On settled high‑pressure days, expect sea‑breeze patterns that freshen late morning, veer with the coastline and ease near sunset. In the inner fairways, wind funnels through sounds and can be gusty around headlands. In the outer skerries and on the Åland Sea, a fresh onshore breeze will raise a short, steep chop that feels larger than the forecast suggests.

Spring and early summer can bring morning fog banks; ensure a radar reflector is hoisted and be confident with sound signals and electronic navigation. Thunderstorms are possible on humid afternoons—plan to be settled before the worst of the heat. Autumn features more frequent gales from the west and northwest.

Tidal range is negligible—typically a few centimetres—but barometric set‑up can shift levels by 0.3–0.6 m, occasionally more. Currents are weak except close to narrow sounds and in the main fairways. The Baltic is brackish, so expect slightly reduced buoyancy. Build plans that avoid prolonged lee shores in northerlies and allow extra time for wind‑over‑current chop at skerry gaps and fairway entrances.

Getting there

By air, Stockholm Arlanda Airport sits within Uppland and is the most convenient gateway. From Arlanda, Norrtälje is about 60–75 minutes by road, and Furusund or Kapellskär around 75–90 minutes. Stockholm Bromma also has domestic and regional links. Pre‑booked taxis and private transfers are widely available; allow extra time on Friday afternoons in peak season.

By road and public transport, frequent coaches connect Stockholm and Arlanda with Norrtälje and onward coastal villages. Local buses serve Furusund, Räfsnäs, Kapellskär and Grisslehamn. Trains run to Uppsala; from there, buses connect to Östhammar and Öregrund. If you plan a one‑way route by public transport, verify weekend timetables in advance.

By sea, ferries run from Grisslehamn to Åland (Eckerö) and from Kapellskär to Åland and southwest Finland. These links are useful if you are combining cruising grounds or arranging crew changes. Parking is available at many guest harbours; confirm maximum stay and fees with harbour staff.

Chartering

Where to charter: Most bareboats serving Uppland are based in the broader Stockholm region (e.g., Lidingö, Saltsjöbaden, Vaxholm). A handful of operators and clubs offer pick‑ups in Roslagen (Norrtälje, Furusund or Räfsnäs) by prior arrangement. Expect a mix of modern production monohulls (30–45 ft) and robust Scandinavian cruisers designed for archipelago sailing. Catamarans are less common but can be found with larger operators.

How it works: Weekly charters typically run Saturday–Saturday in July–August, with more flexible start days in shoulder months. One‑way charters are uncommon but sometimes possible by arrangement within the archipelago. Skippered options are available and can be a smart choice if you are new to Baltic pilotage.

Costs and provisioning: Peak‑season prices are lower than the Mediterranean but higher than much of continental northern Europe. Berthing fees in guest harbours are moderate and usually include showers; pump‑out is widely available and often free. Provision in Norrtälje, Östhammar and Öregrund; many islands have seasonal shops. Diesel and water are available at key guest harbours and some fuel jetties—plan ahead outside July–August.

What to expect onboard: Baltic charter boats are typically well‑equipped for close pilotage with large‑scale charts, plotter, heating, shorepower and long shorelines for rock mooring. Ask in advance about anchor windlass specifications, spare lines, fender boards for granite, and whether detailed large‑scale private charts are provided. A lightweight stern anchor and additional warps are useful in coves.

Licences and formalities

Certification: Sweden does not mandate a licence for operating a leisure boat under Swedish flag in coastal waters, but charter companies generally require evidence of competence—typically an ICC (International Certificate of Competence) or RYA Day Skipper (practical). A VHF Short Range Certificate (SRC) is commonly requested if the vessel carries VHF. Skippers should evidence recent tidal or non‑tidal coastal miles and experience mooring with shorelines.

Customs and immigration: Sweden is in the EU and Schengen Area. If you are arriving by private yacht from another Schengen port, routine formalities are minimal. Fly the Swedish courtesy flag when in territorial waters and carry passports and charter papers onboard.

Environmental rules: Discharge of toilet waste to the sea is prohibited; use holding tanks and shore pump‑out stations. Respect nature‑reserve restrictions and seasonal bird‑nesting closures. Anchoring on private jetties is not permitted without permission. Rubbish disposal is well provided for in guest harbours; recycling is the norm. Ashore, Sweden’s right of public access (allemansrätten) encourages responsible enjoyment—keep distance from homes and leave no trace.

Navigation and safety: Charts and marks are excellent, but numerous off‑lying rocks demand precise pilotage. Use large‑scale charts (paper or official vector) and follow sector lights and leading lines. Depths shelve steeply around skerries; approach at low speed. Carry long shorelines for stern‑to‑rock mooring and fender boards for rough granite. Night navigation is feasible with care, but many crews prefer to arrive by late afternoon on account of intricate pilotage and unlit rocks. Observe local speed limits (often 5–8 knots) in narrow channels, display an anchor light at night and keep a listening watch on VHF Ch 16 when near fairways.

Anchorages and marinas

Key guest harbours

• Norrtälje Gästhamn: In the heart of town; sheltered; fuel, water, power, showers and easy provisioning.
• Furusund: Pleasant stop on the inner fairway with berths, diesel and restaurant.
• Arholma: Well‑run guest harbour with good shelter; shorelines useful for rock mooring nearby.
• Fejan: Small, friendly harbour in the outer skerries; café and hostel in season.
• Grisslehamn: Handy for the Åland ferry; choose berths with care in strong northerlies.
• Öregrund Gästhamn: Historic setting, good facilities and cafés; a highlight in northern Uppland.
• Östhammar Gästhamn: Central, sheltered and practical for re‑provisioning.

Summer weekends are popular; arrive mid‑afternoon for the best choice of berths. Harbour payment is typically via card or mobile app, with codes for facilities provided on receipt. Staff are helpful and can advise on local walks, recycling and pump‑out locations.

Natural anchorages and mooring style

The outer archipelago offers countless granite notches with excellent holding and shelter from one or two quadrants. Norrpada, Rödlöga and the skerries around Arholma are classics. The Swedish norm is to go bow‑to or stern‑to the rock with two long stern lines to trees or rings; use a bow anchor on short scope and approach slowly to avoid prop wash near rocks. In settled weather you can also take free public mooring buoys where available. Rig lines before entering the cove, brief the crew and approach with the sun behind you if possible to read the water.

Fees, fuel and water

Guest harbour fees are moderate and usually include showers and Wi‑Fi; electricity may be extra. Pump‑out is free or low‑cost at many jetties. Fuel is available at Norrtälje, Furusund, Räfsnäs/Kapellskär area, Öregrund and Östhammar; call ahead outside July–August for opening hours. Top up water whenever convenient—smaller outposts can be busy at peak times.

Hazards and local tips

• Rocks extend well off visible shorelines; do not cut corners.
• Watch for ferries on the Kapellskär and Grisslehamn routes; give a wide berth and monitor VHF.
• Fog can settle quickly in early summer; have a plan to wait it out in a nearby harbour.
• Many nature reserves restrict landing or pets during nesting season; check local notices.

Large‑scale charts make life easier—zoom in early on the plotter and confirm features visually. Sunglasses with polarised lenses help spot rocks and weed beds. When in doubt, slow down and realign on the leading marks before proceeding.
