It's doable, but gets technical along the ridges. You'll need crampons and an ice ax on Bjelašnica and on the section from Drstva to Vito. Best to do it on tour skis or snowshoes. Also be aware that most of the mountain huts only operate during the summer and weekends, and everyone has left the village of Lukomir.
Arrangements can be made for accommodation in Stanari, Umoljani and Tusila.
