Before you go, buy 1 Serviced Hut Ticket (green for adults, orange for youth) or 3 Standard Hut Tickets (blue for adults, yellow for youth) for each night's stay. Put these in the honesty box at the hut. Or buy a Backcountry Hut Pass for unlimited use at most Serviced and Standard huts for a 6 or 12 month period.
