Leave Stockholm's Strömkajen ferry terminal on a Tuesday morning in July and by noon you're in a different world. The boat threads east through islands that begin close-packed and urban – Djurgården, Lidingö, Nacka – and gradually thin out into something wilder. By the time you reach Sandhamn, three hours out, the water is open Baltic, the islands are bare granite, and Stockholm feels like a memory from a different season.
The Stockholm archipelago contains approximately 27,000 islands, islets and rocks. The number is precise in the way that large estimates of natural things are precise: it depends entirely on what you're willing to call an island. Some of these are substantial – Värmdö, Ljusterö, Ornö – with permanent populations, car ferries, supermarkets and summer houses that have been in the same families for four generations. Others are barely large enough to land a kayak on. All of them are theoretically yours, under Allemansrätten, for a night or two.
Kayaking is not the only way to experience the archipelago, but it is the best one. It puts you at water level, which is where the archipelago lives. You slip between islands through channels that motor boats can't navigate. You hear the wind and the water and nothing else. You stop when you want, sleep where you like, and move at a pace that lets the landscape actually reach you.
Reaching the Islands
Waxholmsbolaget operates the archipelago ferry network from central Stockholm, and it's excellent – cheap, frequent, and covering about forty destinations. For kayakers, the most popular strategy is to take the ferry out to a hub island and hire kayaks locally, rather than lugging your own through the city. Sandhamn, Möja, Utö and Finnhamn all have rental operations that cater to this.
Sandhamn is the outer archipelago's social centre – a small sailing village with a proper harbour, a handful of restaurants and a distinctive clubhouse culture built around the Royal Swedish Yacht Club, which has been here since 1897. In July it's lively without being overrun. The main village is car-free (there are no roads for cars), and the sailing boats moored three-deep along the jetties create a visual spectacle that feels genuinely earned, this far out to sea.
Möja is quieter and more agricultural – there are actual farms here, producing eggs and vegetables sold through a small cooperative shop that operates on the honour system when no one's minding it. The island has a modest café and a church with a view across the water that's been the subject of Swedish landscape paintings for a century and a half.
🚤 Ferry vs. Kayak: The Honest Comparison
The Waxholmsbolaget ferry is the easy option and genuinely enjoyable. Kayaking gives you access to perhaps half the islands that the ferries skip entirely – the small, uninhabited ones where you'll find the best wild camping. If time is limited, take the ferry out to Sandhamn and hire a kayak for day explorations. If you have four days or more, paddle the whole way.
Wild Camping Under Allemansrätten
This is the part that people from outside Sweden find genuinely difficult to believe. You can camp on any island in the archipelago – any of the 27,000 – for one or two nights, without asking anyone's permission, without paying anything, without even necessarily knowing whose land it technically is. Allemansrätten, the right to roam, is written into the Swedish constitution. The only rules are: don't disturb the landowner's use of the land, don't camp within sight of a dwelling, leave no trace, and don't outstay two nights in one spot.
In practice, on the outer archipelago's uninhabited islands, this means you have a private island for the night. You paddle in, pull the kayak up onto the granite, put your tent on a flat section of rock or moss, build a small fire if conditions allow (there are rules about this during dry periods), eat your dinner watching the sun not quite set at ten in the evening, and wake up to the sound of eider ducks on the water.
It is the single best free experience available to a traveller in Europe. I've done it four times and it still feels unreal each time – the ownership, the quiet, the quality of light at northern latitudes in July, the way the granite holds the warmth of the sun long after the air begins to cool.
What the Kayaking Is Actually Like
The inner and middle archipelago are sheltered and calm. Beginners can manage them entirely comfortably. The outer archipelago, beyond Sandhamn and towards the open Baltic, requires more care – swells and wind can develop quickly, and the distances between islands grow larger. Rental companies will assess conditions and advise honestly; take their advice seriously.
A reasonable day of paddling covers twenty to thirty kilometres without excessive effort. The water in July reaches seventeen to twenty degrees Celsius in sheltered bays – genuinely swimmable, not just technically swimmable. You'll want to swim. Everyone does. There's a particular pleasure in pulling up on a warm granite ledge, jumping into clear Baltic water, and then lying in the sun to dry while eating a piece of bread with the slightly salty butter that Swedish shops sell in blocks.
Kayak hire typically costs around 400–600 SEK per day for a single, 600–900 SEK for a double. Most rental places will also rent waterproof bags for your camping kit, which is non-negotiable if you're sleeping out. Get the dry bags. A wet sleeping bag at 9pm on an uninhabited island is not a romantic problem.
🦟 The Mosquito Question
Mosquitoes are real in the archipelago, particularly on the larger wooded islands and in sheltered inlets in June and early July. DEET-based repellent works. The outer, more exposed granite islands have far fewer – the wind keeps them down. By August, the problem largely resolves itself. It is not a reason to stay home. It is a reason to pack repellent.
The Archipelago Season, Month by Month
The archipelago season runs June through September. June is beautiful – long days, empty islands, wildflowers – but the water is still cold (twelve to fourteen degrees) and some rental operations are just getting started for the season. July is peak, with the warmest water, the liveliest atmosphere, and the longest usable days. Book accommodation and kayak rental in advance for July.
August is quietly the best month for those who can manage the timing. The summer crowds begin to thin after the first week. The water is at its warmest. The evenings start to darken just enough that you see proper sunsets again – deep orange and red over the outer islands around nine in the evening. The crayfish season opens in August, which means harbours and dockside restaurants start serving kräftskiva spreads. It is not a hardship.
September brings the first touch of autumn colour and near-total solitude. The ferries still run, the water is still swimmable for the committed, and the quality of light in the archipelago in September – low, golden, raking across the granite at shallow angles – is something photographers come from across Europe to capture.
