The bridge from Remøy to Runde is only one car width. The island is very popular with German and Dutch tourist in campers. Scan the bridge before entering it. If you see a vehicle coming, stay at the bottom until it is off the bridge. If you are at the top of the bridge and see a vehicle entering the bridge, stop at the wide place at the top and let the car pass.
The cattle on the islands are not used to traffic. In fact, they often seem not to know what you want, which is just to pass. They know their rights and won't budge an inch whatever you do. It took us a quarter of an hour to persuade the cows in the picture to move out of the way. We had no choice, there was no other road but this from the island of Sandsoy to Voksa.
When we were staying on Runde in August, there were just a few midges making a nuisance of themselves, especially in the evening, when the wind died down. There may have been many more earlier in the season. Since the village is situated on the coast, you shouldn't expect too many, not all the time anyway, but it depends on the wind.
When you come close to Runde, you will have to go along a one-lane dike and then also a long one-lane bridge. Watch out for cars coming from the opposite direction at the other end - driving backwards along the narrow road might be really awkward. There is a tunnel just past the bridge, short but also narrow and dark. Watch out , for, although you can see from the distance if there is anything going into it at the other end, a speeding car might give you a surprise.
