It is certainly "off the beaten path", but well worth a visit. While there is plenty to do at the Heydalur site itself, we used it as a base for day trips to other parts of the area.
The valley is just beautiful. And the Country Inn, while a bit rustic, has everything you need. Rooms are comfortable and equipped with all you need (including wifi).
The staff could not be better - personable, knowledgable and willing to accomodate special requests.
We had dinner there every night and it was delicious - from freshly caught trout to Stella's delicious stuffed chicken breasts.
