Address: Kelvenne Padasjoki
Located in Padasjoki, southern Lake Päijänne, the 8-kilometre-long Kelvenne is one of the largest esker islands of Finland. Despite the largescale plans for holiday resort development of the 1960s, Kelvenne has remained an unbuilt island and is part of the Päijänne National Park that was established in 1993. It is also one of the most valuable sites of the Salpausselkä Aspiring UNESCO Global Geopark.
Kelvenne Island provides hikers, boaters and paddlers with wonderful sandy beaches, pine forests and groves of leafy vegetation. Sheltered, deep kettle hole bays serve as natural harbours, and a 9-kilometre-long hiking trail runs through the island. Hiking along the marked trail is a good way to explore the beautiful shoreline landscape, as well as the forest terrain on the interior parts of the island. The trail occasionally rises up to the top of the esker, extending from Kirkkosalmi to Likolahti. There are several campfire sites along the route. Lovely beaches can be found at Kirkkosalmi, Hinttolanhiekka, Kyyränlahti and Isohieta, among others.
Please follow the national park rules and regulations to ensure the preservation of nature.
Kelvenne can only be reached by boat. The municipalities of the area – Padasjoki, Asikkala and Sysmä - have guest harbours with services, and entrepreneurs offer taxi boat, cruise and ferry services.
Traces of the Ice Age
Kelvenne Island was formed around 11,500 years ago at the end of the last Ice Age. Gravel and sand, carried and sorted by the meltwaters from the continental ice sheet, were deposited at the bed of a glacial meltwater stream, while the margin of the melting continental ice sheet was slowly withdrawing.
The deep kettle holes formed next to the island are remnants of enormous blocks of ice that became trapped in the sand and slowly melted there, leaving behind cone-shaped holes. Some of them have turned into small mires. Unique features of the island include a kettle hole pond called Kelvenneenlampi and deep bays formed by underwater kettle holes. The water at the bottom of these kettle hole bays remains cool even during the hottest days of summer.
Kelvenne is part of the picturesque chain of esker islands between the open waters of Hinttolanselkä and Tehinselkä. The islands and the underwater ridges between them form an impressive continuum stretching all the way to the continent. At its highest point, Kelvenne rises more than 50 metres above the surface of Lake Päijänne.
