All together the three islands, Western Bolæren, Middle Bolæren and Eastern Bolæren cover over 2 square kilometers. In addition to this there are over 40 smaller islands, islets and skerries around the main islands. Due to the rich and varied flora and fauna that exists in the area, much of the archipelago is part of the Færder national park.
Transport
The only way to reach Bolærne is by boat. People will prefer to travel out in their own boat if they have one, but there is also a ferry which leaves daily from the town of Tønsberg in the summer. For more information on the ferry go to the official website Flybåten.no

several burial mounds from the viking age and a grand decidous forest. The Earls lodge is also a popular attraction. The most common way to access the island is from Kongshavnsundet.
Western Bolæren
Not as visited as the two other islands in summer, Western Bolæren nonetheless boasts many nice sights and swimming spots. Accessed mostly by the main quay at Jenserud, it is ideal for a quiet day out enjoying nature. There is a café, several cabins that can be rented and a big area where one can pitch tents for free. It has a coastal path, burial mounds, a viking camp and several fine beaches.
Eastern Bolæren
The most popular island of the three, Eastern Bolæren shows the strongest signs of human influence. Most of the buildings are situated around the guest port on the west side. These include a small hotel for overnight stay, a resturant and a kiosk. Bolærne fort organises guided trips of the islands defensive fortifications, but one may also walk among the bunkers and trenches at leisure. Like the two others, Eastern Bolæren has several bathing spots and paths crisscrossing the forests and rocks. There is also a designated area for pitching tents.
