Discover Banff has a wide variety of tours that include tours of Banff town, Lake Louise, various canyons, and other areas of the Park and the surrounding area. The guides are great and really knowledgable. I would suggest one tour from them or from another tour operator to get a feel of the park.
Discover Banff provides transportation and any needed equipment such as hiking poles, cleats, or snow shoes. They also give hot chocolate during the tour to take a little break. Discover Banff provides a nice way to spend a few hours to orient yourself in Banff.
