Looks like there is a trail head near Hoft or Hofta to the Rouburgstulen tourist hytte http://www.ut.no/hytte/3.2196/
Road from Sognefjell Road (rv. 55) Boverdalen.
Raubergstulen lies at the northern Galdhøpiggmassivet middle of the northern part of Jotunheimen. The place is a great starting point for trips to Galdhøpiggen peak.

Continue south to the Juvasshytta:

Juvasshytta located north of Jotunheimen and is the closest cottage to
Galdhøpiggen. The cottage has great views Galdhøpiggmassivet and
Glittertinden among other things. There are daily passage over Ugly
Brean Galdhøpiggen summer season. The cottage is the second highest

Along the road a little way up the trail takes straight south into the
terrain. A sharp rise east of Dugurdskampen before the trail passes
the road and continue the heating. Slightly weaker but still steady
climb past Juvasshøe, where the path splits for route towards
Heimresætre and Spiterstulen passed about 250 meters before
Juvasshytta.

Note that I have not visited these huts but have spent the night at Spiterstulen http://www.ut.no/hytte/3.2003/ to the south during a ski tour. The Jotunheim is well worth the visit. If you had an extra day, you could spend the night at Juvasshytta then walk back the next day. Juvasshytta has showers and 220 volt power. http://juvasshytta.no/

Type: Hiking

Duration: 6 hours + Bereg running time for an adult male, in good
shape, with no breaks. Read more about the timing here grading: medium+

fits: Adult, senior

Go from Krossbu to Veslbreatinden. The terrain up is easy and gentle
climb. This is the just over most part of the trip, with a climb of
about 800 meters. Continue from Veslebreatinden and climb the
Hurrbreatinden, Veslfjelltinden and attic, on the way to Jotunheimen
Fjellstue. The last stretching from attic to Jotunheimen Fjellstue it
is about 1100 meters, in varied terrain.

See elevation profile. Starts at 1275 moh, ascends to three “toppers” over 2000 moh between 6 and 11 km from Krossbu then descends to the Jotuhheimen hut. You would likely want to just walk to the “toppers” then return to Krossbu to keep the walk to a 12 to 20 km walk.
