Mývatn gets its name from the "mý" or the midge/blackfly.
It is literally everywhere and gets totally on one's nerve. The best thing is to keep one of your hands above your head, as they always go for the highest point, but there is a limit to for how long one can do that.
I camped for one night at Mývatn, but I will stay inside for my next trip. The blackfly is just too annoying. It did not bite me, but was everywhere, in my face and ears and eyes.
Anglers use net here when they are fishing in Lake Mývatn. Sometimes one encounters black clouds of the fly, as you can see from my photos.
Leirhnjùkur and Krafla tinker is a must for people that visit Iceland and Myvatn.This is one of the most dangerous area of Iceland, but it is always full of tourists. If you wan't nave trouble follow the path and don't walk over the lava. By the way there is no problem, you can visit this wonderful place with tranquillity without danger. You must think that there is a eruption all Icelandic people come here to see that event!!!!!
