FATMAP difficulty grade
This is a spectacular and a real alpine adventure.
Because of it's remoteness this route is less trafficked then the Skagastølsridge, so there's a good chance you will have the mountain for yourself.
The trip starts from Turtagrø.
Follow the road in Helgedalen and the climb up to the dam.
From here you have two choices.
You can ascend Gjertvasstind from the east ridge(1) or from the icefall(2). (1) Follow the trail in Styggedalen, passing 3 small lakes.
Pass Simlenosi on the south side and go down to Gjertvatnet.
From here you have to drop some vertical meters to the south before reaching the east ridge.
Follow the ridge to the summit, some scrambling is required. (2) At the second lake in Styggedalen, head to the south and you will soon enter the glacier.
Follow the glacier at it's most gentle slope up to Gjertvasskaret.
Depending on the conditions, there might be crevasses and blue ice in the steep sections.
If so, this is a highly demanding route, requiring additional belaying and ice-climbing equipment.
As a generally advice, the glacier has the best conditions pre August, but there is big annual variations.
From Gjertvasskaret, base of the climb at the north side.
One pitch, then easy scrambling at some slabs to the summit. From Gjertvasstind, abseil down to Gjertvasskaret.
Follow the ridge at it's highest point westwards up to Styggedalstinden.
There's some scrambling, but pretty straight forward.
Easy traverse over Styggedalstindane to the west summit.
Descend to the ridge to Centraltind, by going a little bit down to the south face.
Easy westwards over the ridge until it steepens.
From here 3 pitches (3+) to the summit of Centraltind. Centraltind is a very nice bivouac spot with a broad summit plateau.
Alternatively you can do a bivouac at Styggedalsryggen.
On day two, continue on the ridge towards Vetle Skagastølstind, with one abseil.
From here there are two alternatives.
(1) Ascend Vetle Skagastølstind and finish the traverse by reversing Skagastølsryggen to the north.
This involves two short (30 meters) abseils and one 60 meters abseil.
Exposed, but easy terrain between Vetle and Midtre Skagastølstind, involves some down climbs.
At V-skar comes the 60 meter abseil, before you can walk the rest of the ridge to Nordre Skagastølstind.
From here follow the track back to Turtagrø.
The GPX-track of this description follows this alternative. (2) Finish the traverse by ascending Store Skagastølstind, two pitches from Mohns skar, and abseil down the south face and return to Turtagrø via Hytta på bandet and north through Skagadalen.
