No special access issues
Park by the side of the road a bit east of Nybruddet. Walk southeast across the marsh aiming for the hillside where a small stream runs down. Here you should find a small, visible but not very well trodden, path. Walk up hill with the cliff face on you left til you find the steep roof. Depending on the time of the year walk in time is 5-10 mins.
Not a child friendly approach.
