The quota is in place to protect the fragile alpine area. This means that not everyone will be able to reserve bus access. There are no restrictions on the number of people who hike the 13 km trail. Cycling is not permitted on the Lake O'Hara fire road. Pets are not allowed on the bus.
Visitors can walk their pets into the valley.
All vehicles in the parking lot require a valid National Park pass. These can be purchased at any Park Service Centre or from the attendant at the bus. Persons with a disability are asked to consult with staff on special needs. It is possible to visit Lake O'Hara without having made reservations three months in advance. Be sure to show up early, as a line-up usually forms before the doors open.
