I have ~18 days to hike across Iceland during August. I'm a good hiker (last summer I spent 40 days across the Alps) and I'll be alone. I'm looking for advice for my itinerary (southbound).

I'll have a GPS and I looooove going off-road (wilder == better), but with the glaciers and the rivers I can't go without preparing my route well. If possible, I'd like to avoid the most dangerous rivers (wide or with strong stream).

For the northern part, I'll probably follow [this track](http://www.openrunner.com/index.php?id=4062483) (Asbyrgi - Nyidalur).

Then I'd love to go see the Kerlingarfjoll massif (so hiking in the south of the Hofsjökull glacier), then going south to Sveinsgil and Landmannalaugar. Finally, I could follow the Landmannalaugar trek to go to the coast.

With a map:

*In red the part I'm not sure if feasible*

**But I don't know if it's possible (not too dangerous) to do Nyidalur - Kerlingarfjoll - Landmannalaugar. Is it the case?**

**Are there some detours I should take?
And finally, is this globally a good itinerary?**
