In case you want to bring any electrical appliances with you, here is the system Norway uses: 220 volts and 50 Hz. It is a round pin attachment plug (see picture)
An adapter will allow you to plug an appliance designed for one type of outlet into another type of outlet. Despite the fact that more than a dozen different types of plugs are in use, a typical travel adapter kit usually contains about five adapters which are capable of dealing with most of the outlets shown here. Adapters often manage this versatility by bypassing the ground/earth wire.
Beware: an adapter by itself will not change the electrical voltage. You must be sure that your appliance can handle different voltages (either automatically or through a voltage switches). If it can't, you will need a voltage converter.
Clothing/Shoes/Weather Gear: Even in mid July Norway was cool, most days I needed at least long sleeves. For the bus trip up to Mt. Dalsnibba you will want to have closed toe shoes, at that altitude there is snow on the ground, even in July. With a fleece and a rain coat I was warm enough, you only stop for about 15 minutes. I wish I had brought gloves though, trying to build a snowman without them was really cold!
Even in August it's pretty cold in the fjords region and on the mountains picks there is also snow.
If you climb the mountains, especially if you go on Dalsnibba, a warm coat is definitely a must, but also a rain coat will help.
Photo Equipment: Mandatory. The view of the fjords creates real artists of the camera.
some extra pair of socks in case of bad weather. Rain clothes. perhaps an extra pair of shoes.
Toiletries and Medical Supplies: it would be wise to bring some toilets paper in case there is no paper present at the bathroms at the harbour
Photo Equipment: Bring som extra films. You'll suddenly find someting to photograf and when you're looking for more films your motive is vanished
Camping/Beach/Outdoor Gear: a good tent. sleeping bags food
Miscellaneous: you'll probably meet some mosquitos in the evening.
For 'grounded' plugs, the "chuko" plug and receptacle with side grounding contacts is used (see picture)
The receptacle will also accept the not-grounded plug shown in the previous tip.
