Transportation providers are JT-line (www.jt-line.fi) and Aavalines (www.aavalines.fi, in Finnish) and the departure points are located at the Market Square. You will find the departure points beside "Vallisaari" signs. JT-line departs from the Kolera allas (and during midsummer also from Hakaniemi) and arrives to the Pilotyard jetty at Vallisaari. Aavaline departure point is beside Suomenlinna Island ferry and at Vallisaari the water buss arrives to Torpedonlahti harbor square.

Tourists at Vallisaari and Kuninkaansaari can use the islands' water points, dry toilets, picnic tables and during summer season also the excursion harbour, café, and tour guide services. It is allowed to berth at excursion harbor year round.

The natural environment of Vallisaari is highly sensitive. Please stay on the marked trails. Before visiting Vallisaari, please familiarise yourself with the rules and regulations that apply to the area.

Vallisaari is the most diverse nature destination in the metropolitan area. A record-breaking number of species tell a tale of coexistence between humans and wildlife. For the past decades, Vallisaari and Kuninkaansaari have remained in a natural state.

Impressive Range of Species

At the turn of the millennium, researchers surveyed the biodiversity in more than 200 islands off Helsinki. Vallisaari proved to exhibit the richest flora of all the surveyed islands. Many demanding plant species typical of traditional landscapes thrive on the embankments and grounds surrounding buildings on the island. You may, for example, find hairy oat (Avenula pubescens, parallel scientific name Helictotrichon pubescens) and maiden pink (Dianthus deltoids).

Vallisaari is also home to 1,000 butterfly species. More than a hundred of these are threatened or rare species. Vallisaari serves as a stepping stone for many southern species, offering them, in the island's sunbaked meadows and stands of hardwood, conditions similar to those found in Central Europe. For example, the plumed prominent  (Ptilophora plumigera) thrives on the island. In the sandy soil of the sun-baked meadows, beetles scuttle that are normally found on beaches, including the sand weevil  (Philopedon plagiatus).

The island's common alder (Alnus glutinosa), aspen (Populus tremula), and thickets of  bird cherry (Prunus padus) provide cover for lush vegetation, in which icterine warblers (Hippolais icterina), thrush nightingales (Luscinia luscinia) and Blyth's reed warblers (Acrocephalus dumetorum) sing their song. After sunset, badgers (Meles meles) crawl out of their setts, and bats (Chiroptera) and  eagle-owl (Bubo bubo) take wing. 

Some of the impressive species diversity in Vallisaari is attributable to human action. Activities by the Finnish Defence Forces have kept the embankments and the meadows between fortifications open, thereby enriching the diversity of nature. The calcareous soil of the embankments and the crumbling concrete structures help to maintain communities of rare moss and lichen species.

Favourite Haunt of Bats

Northern bats (Eptesicus nilssonii), whiskered bats (Myotis mystacinus) / Brandt's bats (Myotis brandtii), Daubenton's bats (Myotis daubentonii), grey long-eared bats (Plecotus auritus) and common pipistrelles (Pipistrellus nathusii) fly in Vallinsaari. All of these species are protected.

Fortifications, caves, and old buildings provide bats with breeding and wintering locations. Lush woods, meadows, and ponds ensure that bats have an abundant supply of food. It is crucial for bats that at least some sections of the island remain peaceful, shadowy, and wild.

Species from the East

The Russian history of the island is reflected in the plants found on the Alexander Battery. The hill mustard producing yellow flowers (Bunias orientalis), the grey hoary alyssum (Berteroa incana) of the late summer,  and the rare thyme-leaf dragonhead (Dracocephalum triflorum)  are examples of species that were brought to the island with animal fodder.

On the embankments on the southern tip of Vallisaari, a flightless beetle, Trachyphloeus scabriculus, is found. Like the plants, it is a stowaway from the east. This beetle species, new to Finland, was found in a nature survey conducted by Metsähallitus in 2013.

Thank You, Volunteers

Voluntary work is crucial for the nature in Vallisaari. Before Metsähallitus began work with its partners, in 2013, to open the island to visitors, its paths, grounds around buildings, and embankments were overgrown with vegetation. In collaboration with us, volunteers now look after the nature on the island. In addition, convicts participate in the repair work. All work is always supervised by professionals.
