Driving tours linking scenic viewpoints are one of the great highlights of the Rockies, but to get the most out of the region and appreciate the forces of nature here, you should really do some of the many possible outdoor activities.
Other activities in this broad category are covered in less detail by this site include:
• Soaking in hot springs (try Banff Upper Hot Springs, Miette, Radium, Fairmont)
• Paddling a canoe (try Lake Louise or Moraine Lake)
• Climbing (try Grassi Lakes)
