So you have alreday been here? But you can come back!
In June some roads may be closed, and there are often more rain in May and in June then in July - July or August is better for the tourists on two wheels. And it is often not that cold in July.
Everytime some ask me for advice for a holiday in Norway, I say;
Do not try to see Norway from Kristiansand to Nordkapp (Noth Cape) in one week!
It is better to stay in the south part, or go up to the midle part of Norway, and spend some time on funny roads in the moiuntains and ride along the fjords.
Keep in mind you can not ride fast on those funny roads and look at the wiev at the same time!
Stay at the same place for two nights may be a good idèa; there are often so many roads in one small area, so you can't see it all in one day.
Relax, have fun, and do not try to see 100% of Norway in one week!
...and tell me you the next time you (all of you!) are going over here; I'll try to meet you where you are if you are not too far from Oslo.

Liv.
