The first hurdle on this approach is getting on the bus to Lake O'Hara. The bus is operated by Parks Canada and is used to control the number of people going to Lake O'Hara. Reservations are difficult to obtain; however an automatic reservation on the bus can be obtained by booking a reservation at the Abbot Pass hut with the Alpine Club of Canada. Persons doing so should carry proof of their reservation because they will not be able to get on the bus without it. The alternative is to walk 10 km up the access road carrying all their equipment.
