Storsand Gård Camping

auto-translated: The facility has a good location, close to Trondheim and the airport. The noise pollution is not only unpleasant during the day but also at night. The proximity of the railroad, airport and road traffic contribute to the noise. The sanitary facilities are in good condition and the price is not justified.

auto-translated: If you can get a spot by the sea, the experience is probably much better than standing on the grassy area just after the small bridge over the railway. You wouldn't even guess that you're 150 meters from the water. Quite noisy due to the train, airport, garbage collection, etc.
The row where we stood had very uneven spots; there was a small ravine in the middle of the wagon where the wheels ended up because something had been dug down.
Expensive camping, 540 NOK plus 15 NOK for a shower. If it's going to be worth the money, you should get a spot by the water.

auto-translated: We arrived in the late afternoon and could only get a parking space on the gravel area in front of the actual campsite. The price at the time of our stay was 540 NOK. This is a flat rate (according to the campsite operator). An additional 15 NOK per 4 minutes of showering would have been added. Unfortunately, the time continues to run even when you turn off the water.
The railway line between the gravel area and the campsite is very noisy. In addition, the road above is used as a “poser” mile. So everything is very noisy.
The operator wrote to me on my Google review that there was a standard price for the pitches. You could easily move to the actual campsite the next day. Unfortunately, many people use this site as a stopover for one night. I have never seen this at any other campsite.
We would not come back, as it was by far the most expensive and worst campsite on our trip, and the price-performance ratio is absolutely not right.
