The Bolærne islands lie in the outer Oslofjord, just off Nøtterøy. Three main islands are surrounded by smaller islands and skerries, offering coastal walks, swimming spots and thousands of years of maritime and military history. Choose Østre Bolæren for guest harbour facilities, dining and activities, Mellom Bolæren for woodland walks and historic sites, or Vestre Bolæren for beaches and traditional coastal life. Reach the islands by seasonal passenger boat, water taxi or private boat.
Østre Bolæren – guest harbour and military history
Østre Bolæren offers walking trails, sheltered swimming spots, a guest harbour and options for dining and accommodation. The higher ground provides sweeping views across the Oslofjord. Explore old gun emplacements, a signal station and other remains of the island's military past, or enjoy a relaxing break beside the harbour.
Mellom Bolæren – coastal trails and cultural heritage
Mellom Bolæren is known for its old deciduous woodland, meadows, restored smallholdings and historic buildings. Follow the 1.5-kilometre coastal trail through a landscape rich in nature and cultural heritage. Along the way, discover ancient burial cairns, traditional farm buildings and Grevestuen, a historic lodge associated with the Counts of Jarlsberg. The island also holds a darker chapter of history. Remains of a camp for Soviet prisoners of war from the Second World War can still be found here. Please treat this memorial site with respect.
Vestre Bolæren – beaches and coastal traditions
Vestre Bolæren combines peaceful coastal scenery with traces of traditional island life. Explore walking trails, visit the guest harbour or discover the historic settlement at Jensesund. The island also has Bronze Age burial cairns, maritime heritage and places to swim. At Kalvenga in the northern part of the island, you will find a designated camping area and access to the coast.
From the Bronze Age to military history
Ancient burial cairns show that people have used the Bolærne islands for thousands of years. In later centuries, fishermen, pilots and seafarers made their homes here. The Norwegian Armed Forces took over the islands in 1916, restricting public access for decades. In 2004, the islands reopened to visitors. Today, their footpaths, historic buildings and coastal landscapes offer a glimpse into this long history.
Plan your visit
Bolærne is suitable for both day trips and longer stays. Accommodation is available on the islands, including historic buildings and coastal cabins. Seasonal passenger boats operate from Husvik near Tønsberg. Check departure times, island stops and return connections before travelling. You can also arrange a water taxi or arrive by private boat.
Protect the islands
Much of Bolærne lies within Færder National Park. Follow marked trails, respect nesting birds and leave archaeological remains undisturbed. Special rules apply to camping, fires, dogs and access to protected areas. Check local regulations before your visit and take your rubbish home.
