Visit the Banff Museum, Banff Park Museum, Whyte Museum or the Buffalo Nations Luxton Museum that feature art, culture and history of Banff and the Canadian Rockies. Most of the museums remain open daily except on holiday days. Check their websites the current winter hours.
For helicopter tours we recommend Rockies Heli Canada. Please see below for their tours along the Icefields Parkway. Additional information can be found at: http://www.rockiesheli.com/
