Munkholmen is an islet that lies smack in the fjord just a few minutes boatride from the city of Trondheim.
Like many similar places, Robben Island and Alcatraz are among the most famous, it has historically been used as a prison (from 1680-1850): Prior to that it had been used as a monastery, execution site and fort. After the prison period, it was again used as a fort.
Today Munkholmen is a recreation area with a small beach and green lawns that you may relax on during the summer. There is a small cosy café and restaurant that sells good food and beverages, and there is also a shop selling handicrafts and souvenirs.
Munkholmen i open to the public from May to September. A boat takes passengers to the islet on an hourly schedule, every half hour when there is a lot of traffic. The boat price is 70 NOK for a return ticket (2012 prices). There is a guided tour every hour, which costs 30 NOK.
There is not much happening on Munkholmen except for visiting the cafe/restaurant/shop and joining the guided tour. And therein is much of its charm. The place is best enjoyed while lazing about and for getting an overview of Trondheim.
