The glacial river Bláfjallakvísl is a very challenging for both hikers AND DRIVERS! We advise hikers to go 200 m. up the river to find a wider spot to cross! Speak to the wardens on the way!
The river Lindaá on road F88 on the way to Askja can be difficult to cross. We advise smaller 4×4 cars (Jimny, Rav etc.) to take the eastern route instead – roads F905 and F910!
