The Faroes consists of 18 "official" islands, to that comes islets and rock stacks. All but one of the 18 are inhabited, although in some cases only by one or two families. I visited eight islands; the six that are connected by roads and tunnels, and two that are easily reached by boat.
Originally, the Faroes were colonised from Norway, but as Norway was in union with Denmark for over 400 years, the islands drifted over to the Danes. The Faroese think of it as a country of its own, but which is part of the Kingdom of Denmark. The Faroes are, in difference to Denmark proper, not a member of the European Union.
They say that the best time of the year to go to the Faroes is in May/June when the weather is mainly dry. (Which is necessarily not the same as sunny.) I went there in the first week of August and by then the weather had become more unstable.
Faroes is not the place where you go around and look for a hotel when evening comes, but you need to book all nights in advance. I booked a package with flight + hotel + rental car through a Faroese travel agency GreenGate, and they had some problems to find me lodging for all nights. Even if the Faroes have bus conncetions to the smallest villages, a car is still to recommend, since that permits you to stay as long, or as short, you wish in the place you visit. There are no huge distances. From Tórshavn in the south to Viđareiđi in the north there is around 100 km. However, you can't bring the car everywhere. Many say that Mykiness is the best island of them all, and the only ways to go there is by a small boat or by helicopter – that both are prone to cancellation in bad weather. No, I did not go there.
Keep in mind to bring sturdy clothing. The highest temperature ever recorded on the islands is 22°C. Average temperature in summer is 11°C. Winds are strong and fierce, not the least in the mountains. Bring a wind- and waterproof jacket, and also waterproof trousers. And boots. Even if it's not raining when you are walking, the grass may still be wet. Finally, you also need to bring gloves and something to keep your ears warm.
Most villages on the Faroes are small places, and you will not find a place to eat or drink in just but a few of them. If there is a supermarket, you should be able get packaged sandwich there. But some places are too small to have even that. This is good to keep in mind if you are driving all day; lunch may require some planning.
The only guide book I found was the Bradt, but it was perfectly OK.
