Trondheim is the third largest city in Norway, a former capital of Norway and the home of the biggest church in Norway. The city is more than 1000 years old, and used to go under the name Nidaros. The city is thus rich of history, and a well worth destination for tourists.
The best time of the year to see Trondheim is the summer. Since the city is so far north, the sun is up all day, and barely goes down a few hours at night. If you want to see the midnight sun, however, you will have to travel further north than Trondheim, and this might be an idea for tourists wishing to stay a few days in the city. There are buses heading north from Trondheim and they should give discounts to students.
Trondheim is heavily dominated by students, with the university in the city hosting 25,000 students. The total population is about 170,000 people, and the population is thus very young. For visitors who wish to meet locals or people living in the city, it may be a good idea to go out at some of the places in the downtown area around the river Nidelva. Just remember that alcohol is expensive in Norway, so if you are on a tight budget, you may want to drink slow and party hard when you return home instead.
For those seeking a more relaxing holiday, taking the ferry to Munkholmen can be recommended. There you can take a swim, or look at the old monastery or just sunbathing and relaxing. The ferry goes from Ravnkloa to Munkholmen every hour in the summer, but be sure to check out when the ferry is returning to town, because you do not want to be stuck on the island all night (although if it is sunny, it is probably an experience to see the sunset there in the middle of the night).
There are obviously nice things to see within the city as well. The obvious choice for tourists is to see the Nideros Cathedral, which is overlooking the city center. The cathedral is the only cathedral in Norway and the biggest church of Northern Europe. The cathedral is a major pilgrimage site in Northern Europe, and it is a must see if you visit Trondheim. As a small historical fact, the cathedral is reportedly built on top of King Olav Haraldsson’s grave, and it is of course free to see.
Close to the cathedral, you will find the park Marinen. Something I would recommend is to see the sunset from the park, because it is beautiful and you are almost guaranteed to have a good time. In the city center you will also find wooden mansions that are worth seeing. Stiftsgaarden is the biggest, and it is also the King’s residence when he is in town, but Singsaker summer hotel is about as big. It may be, however, that size does not matter, as smaller wooden houses may be just as worth seeing. Bakklandet, which is the eastern side of Nidelva is a place you should definitely take a walk.
There are of course several museums in Trondheim. To see these obviously costs money, but some are probably worth seeing. The Museum of Musical instruments is at Ringve, and you will have to take a bus there. At Ringve you will also find the botanical gardens of Trondheim, which is free to see. Trøndelag folkemuseum is another museum worth seeing for those who wish to see Norwegian housing and lifestyle from old times. Sundays is a good day to visit the museum for people visiting with children, because there are child activities, but by experience these types of museums should be fun for children as well as for adults.
If you want to eat in Trondheim (and you probably do), one place that may be worth the price is the restaurant at the top of the TV-tower. You will have to take a bus to get there, but the restaurant is rotating so you should at least not get tired of the view. Note that restaurants are fairly expensive in Norway, with alcohol raising the price considerably.
There are of course several other things worth seeing in Trondheim. I may have forgotten some of the best sights, but I do hope this will help some of those wishing to see the city. Remember that you can always ask locals for recommendations. Norwegians are very helpful, and English is spoken by everyone.
