Season July to September (but summer snow cover can vary greatly from year to year)
Huts Staffed shelters serve meals (and sell sack lunches). Self-service huts provide stoves and cookware and have nonperishable food for sale (or BYO). Parties of fewer than five don’t need reservations (recommended at Gjendesheim, which is popular). Norwegian huts will not turn away trekkers, but overflow guests get a mattress on the floor.
Cost Expect to pay about 555 to 660 Norwegian kroner per person ($100 to $115; less for children) for lodging and three meals at Norwegian Trekking Association huts (includes discount for $100 membership; contact below). Huts accept major credit cards.
