Parking options (we were traveling with a 6m camper) and possible starting points for the hike are poorly described, as they are almost exclusively used by locals. Therefore, our recommendations are as follows in the form of the newer plus code:
Parking option => XVX9+7XQ Valle, Norway
Start option 1 => XVW8+273 Storvika, Norway
Start option 2 => XVV8+VJ7 Storvika, Norway
The lower part of the hike can therefore be done as a circular route.
Very muddy after rain, so sturdy shoes are recommended.
