# Bothnian Sea National Park

Bothnian Sea National Park (Finnish: Selkämeren kansallispuisto) is a maritime National Park in South-West Finland. About 98% of the park consists of sea and most of it is accessible only by boat.

## Understand

The Bothnian Sea National Park was established in 2011. The main idea is to preserve the underwater nature in the northern Baltic Sea as well as some important nesting sites for pelagic birds. The park is 160 km long in north–south direction but only some 10–20 km wide in west–east direction. The bays, islands, islets and skerries in the park are notable for their birdlife. Also the grey seals are common.
Some islands have remarkable maritime or naval history, Katanpää and Isokari being perhaps the most important ones.

### Visitor centre

Bothnian Sea National Park has no own information hut or nature cabinet. The Nature Centre Haltia in Nuuksio is responsible for information on the park (☏ +358 40-163-6200, info@haltia.com).

## Get in

Making a fire is forbidden if a wildfire warning is in effect.
Dogs must be kept on leash all the time.
Scuba diving is permitted as most of the nature here is underwater. Biking is permitted but the bikers must stay on trails.
Angling and ice fishing are permitted as "everyman's rights" (right to access). For fishing with reel and lure, paying the national fishing fee is required. Most other fishing requires additional permits.

## Get around

    See also: Boating in Finland, Sea kayaking
Getting around this national park mostly requires some sort of boat. There are easy nature trails in the Preiviikinlahti area. Otherwise the easiest way is to participate in some guided tour from mainland towns.
The bird watching towers Eteläranta and Lankoori in Preiviikinlahti area are accessible also by wheelchair (only the latter one is inside the national park).
The terrain on the islands is mostly rough. Forget about prams. Also tours may require you to cope with stony footpaths.
The area is shown on Finnish Nautical Chart Folio E (covering the coast of the Bothnian Sea, 1:50 000). The islands themselves are small enough to be explored without a map.
Beware bird nesting islets and avoid approaching or landing on those.

## See

The main attractions are the vivid birdlife, the lighthouse islands – and the sea, of course. In addition to seabirds the grey seal (Halichoerus grypus) is abundant.
There are a number of bird watching towers around Preiviikinlahti bay in Pori. Of these Leveäkari, Huhtala and Lankoori are located inside the national park. The number of nesting water fowls is notable but during the spring and autumn there are literally thousands of migrating pelagic birds. The Preiviikinlahti has also notable flora with some rare aquatic and semi-aquatic species.
There are marked nature trails on the islands Iso-Enskari, Säppi and Kuuskajaskari, and a trail network in the Preiviikinlahti-Yyteri area on the mainland. The nature trail on the Isokari island is mostly outside the national park itself.
The lighthouses on Kylmäpihlaja, Isokari and Säppi may be visited with guided tours. Kuuskajaskari and Katanpää islands are former military fortresses, the latter one being used until 1999. Katanpää has also served as a prison. Most of these islands have several services including lodging and restaurant. If you are travelling with your own yacht the price for a lighthouse visit is around €10–15/person. Otherwise it might be more convenient to take an arranged tour including meals and transportation from the mainland.
