No special access issues
The parking by Låter is the same as for reaching Strandåtinden wich has a well trodden path. Follow the path east uphill from the north corner of the parking for about 100 vertical meters. Take off to the left (north) about 30 meters before the path crosses the creek. Follow the ridge all the way up to the lake under the north wall. After walking for about 45 min you'l see the first boulder "Utegym" and 10 mins further on you'll reach the lake and large main boulder field.
As always respect the nature and don't litter.
