I’d love to hike across Iceland — but this is not an adventure for any but the hardiest.
Cam “Swami” Honan did it with Kate “Swept Away” Pickett in late August/September, 2023.
This post covers the first 2 stages from Hraunhafnartangi Lighthouse to Lake Mývatn.

Finding protection from the WIND is just one of many problems they faced.

Of course there are other routes across Iceland.
IF you ever consider this adventure, study Cam’s trip reports carefully:
