Absolutely recommend you come here if you are visiting or have visitors in town. It's the perfect tour to get to know and see the middle of Gothenburg. It's only about 45 mins and it goes throughout the entire river of Gothenburg and out into the harbor.
The tour goes under all of the bridges, and then the time in the harbor is spent looking at the massive bridges, boats, and opera house.
The tour guides are super friendly and funny, they speak in both English and Swedish. If you get sea sick I wouldn't worry about this as it doesn't really rock like a typical boat.
The tickets are pretty cheap (around 160sek) and they leave about every half hour. You can always find tickets on the fly we usually just walk up within a few minutes of the tour departing.
