Sognsvann utfartsparkering

auto-translated: Moin, in principle there's nothing wrong with the site if two-day parking for motorhomes wasn't now prohibited. Two dry toilets (with paper) at the end of the car park, 30 m into the forest, were perfectly OK for us. After talking to a local who said that there would only be occasional checks, we took the risk, as did about 20 others. The morning after: Yellow tickets on every windscreen at a price of 660 NOKs (58 €). Hm, the site near the city centre would have been only slightly more expensive.
But still, cycling from a height of 200 metres with a rapid 9 km descent into the city was great, the ascent back up again with our older, non-motorised boxes was exhausting and took 45 minutes.
In short: if you want to take a ticket and don't need a shower, you'll find a nice place and don't have to worry about not having enough space.

auto-translated: It is a pure car park where you can stand for 48 hours free of charge, but it is directly at the lake. Dogs must be kept on a leash at the lake! According to the signs, it is not allowed to cycle around the lake because there are a lot of joggers.
The S-Bahn (suburban railway) is directly above the lake, which takes you directly to the centre. Perfect for 1-2 nights.

No supply/disposal!!!!
