Went to Gullfoss yesterday with Andrea and Brook.
Climbed Hvitagull and Svingersklobb.
Hvitagull in good condition 20min approach from the parking lot; we did follow the road after crossing the gate but is also possible to follow the path to Gullfoss and then turn left and reach the line. we used a fixed rope to abseil, anchor on the ground (frozen stream).
I really suggest Svingersklobb as well, is it on the way few minutes driving back after lower some turns. follow the road to the summer house and then turn to the field before crossing the river.
