Storebjørn is a very beautiful peak with a great view over
Smørstadbreen and its surrounding peaks, between Krossbu and
Leirvassbu. The peak is easiest reachable in March – May on
skis, the road over Sognefjellet usually opens in May, and the
glacier is usually still safe for skiing. Between June and February
you need a rope on the glacier both from Leirvassbu and Krossbu.
There are guided tours from both huts as well.
The cache has a tarrain rating of 5, because of the need of
glacier equipment and experience during summer and skis and glacier
experience during winter/authumn. The cache might be difficult to
find before July each year, but might also be in the open at that
time, depending on snow condition.

The tour is not complete without a full dinner at Leirvassbu, very
good and reasonable price.
