Over 50.000 islands, rocks and skerries
Our main playground and extraordinary haven is the Finnish Archipelago Sea, the largest archipelago in the world with its around 50.000, often tightly clustered, islands. We have been arranging sea kayaking tours in the world's greatest sea kayaking destinasions around the globe since 1995, but still our own Archipelago Sea is the most special area for us, and extraordinary area which we love to take our customers to.
The Archipelago Sea (Finnish: Saaristomeri, Swedish: Skärgårdshavet) is a part of the Baltic Sea between the Gulf of Bothnia, the Gulf of Finland and the Sea of Åland, within Finnish territorial waters. The size of this area is over 8000 square kilometers, of which 2000 square kilometers is land. A massive amount of these islands are uninhabited, a fact which together with the Everyman's rights giving visitors the right to camp on and visit almost every island, makes this area a very unique place for wilderness enthusiasts.
While the salinity of the sea water in the Northern Sea is around 3,5% the innner Baltic Sea including the Archipelago Sea has a very low salinity level, around 0,5%. Because of this, the water is perfect for swimming in and even for using when cooking food, although a tiny bit too salty to use as drinking water. The low salinity level affects the water fauna also: Here you find fishes that in most other parts of the world are specific for lakes: Perches, pikes, baltic herring and whitefish are caught a lot. Salmon can also be caught even if they are not as common to get. For fishing with a casting rod or nets, you need a fishing permit (no permit needed if you are under 18 or over 64 years old). More about the permits and an on-line store for them can be found here.
Water, wind and tides
The water temperature in the archipelago varies a lot. During winter, the sea freezes and where there is no ice, the surface water temperature is only 0 degrees centigrade. During spring, the water temperature quickly rises, and in June to August the water temperature climbs close to or even above 21 degrees centigrade. In late October, the water temperature is back at below 10 degrees centigrade and going downwards.
Because the Baltic Sea is relatively small and acts as a closed basin with only a narrow entrance to the west, the total tidal height difference in the area is under three centimeters. Passing low and high atmosperic pressures can, however, change the water height in the archipelago, but not more than +-40cm during even a quite extreme day. Do lift your kayak up on dry ground properly during nights still, in order to avoid nasty surprises in the morning.
The Archipelago Sea is well protected from extreme wave buildup even in harsher wind conditions, but on more open straits, up to one meeter high waves can be encountered on very windy days. Almost anywhere in the inner archipelago area it is easy to find shelter for for waves by planning the route well. The area is rarely hit by high wind speeds during summertime. However, sea breeze develops on sunny days in May and the beginning of June due to cold waters and warm land masses, and this can cause southerly to south-westerly winds with wind speeds up to 10 m/s some days. Such days it is still easy to find shelter amongst the islands. From late September to November, low pressures press through to the Baltic Sea, causing windy days much more often than during summer.
Summers in the Archipelago Sea are sunny and perfectly warm, with day and nigh temperatures varying between 16 and 25 degrees centigrades in mid-June to late August. The midnight sun lights up the archipelago around the clock especially around midsummer, while a headtorch is needed from late August onwards if you want to wander around in the night.
We work in a close cooperation with the islanders living in the Archipelago Sea, and on our tours, you will get an insight in the archipelago culture and lifestyle.
Some of the larger islands in the Finnish Archipelago Sea are inhabited and a few of them are connected by ferries and bridges. The Archipelago Sea is a significant destination for visitors wanting to experience the wilderness, beauty and culture of the area. Together with the everyman's rights concerning camping and moving around almost anywhere where you do not disturb others makes this is a great destination for outdoor and nature enthusiasts.
The archipelago is a result of the last ice age, Weichel, which began around 110.000 years ago and ended around 10.000 years ago. The islands began emerging from the sea shortly after the ice age. Due to the post-glacial rebound the process is still going on, with new skerries and islands being slowly created and old ones enlarged or merged. The current rate of rebound is between 4 and 10 millimetres a year. The islands consist mainly of granite and gneiss. The sea is very shallow, with a mean depth of only a little over 20 meters.
WildlifeThe Archipelago Sea with its varying nature offers a unique and diverse environment for wildlife. While the islands closer to mainland are often covered by forests, the outer archipelago consists of islands with very sparse or no growth at all. Sea eagles of the White Tailed Eagles (Haliaeetus albicilla) species are something that you often spot both far and close.
Safety in the archipelago
Although the archipelago is mostly well sheltered from the highest wind-speeds and from big waves, these do occour, and we do not rent equipment for unguided tours to people not competent with kayak rescues and manouvering techniques. The water temperature vary very much (read more above), and during spring and fall, it is essential to be well protected while on the water for safety reasons (we do have dry-suits for rent).
In our area, there are no poisonous or otherwise dangerous sea animals. On some of the islands, vipers (vipera berus) which is Europe's most common poisonous snake, can be found. Bites from these are very rare, but could be dangerous and a doctor should always be contacted immediately if bitten by one (the last fatal snake bite in Finland happened in 1998, but it is worth being careful).Vipers are very frightened of people, and as long as you do your presence known and avoid the only places between stones where they can hide, it is very rare to see them. Ticks, possibly bearing borrelia and tick-born encephalitis, are found on some but not all islands; avoiding walking in high, especielly wetland grass, and/or checking your body for these in the evenings is recommendable. This said, the Finnish nature is the safest or one of the safest countries in the world also from the aspect of dangers in nature.
