We included the Cave & Basin National Historic Site as part of an all-day bicycle tour that started/ended on Tunnel Mountain Drive and also included the Banff Visitor Centre, CPR Station, Fenland Trail, Vermillion Drive/Lakes, a short stretch of the Rocky Mountain Legacy Trail from Vermillion Drive to the Bow Valley Parkway (1A), Bow River Trail, Marsh Trail, and Sundance Trail. It was a fantastic bicycle tour and Vermillion Lakes was a nice part of it.
Wow! That sounds like a great day of exploring. We're so glad to hear you enjoyed your visit to Banff.
