Avoid all road sign reference to Tunnel Mountain. Instead look for the Banff Centre, Buffalo or Wolverine Streets, Julien Rd and Tunnel Mountain Drive. This is all in the south end of Banff downtown. There are two trail heads, the lower is on Julien Rd and the slightly higher with limited parking on Tunnel Mountain Drive. Nice views, good phone access, lots of summer walkers. Operate eithe from one of two deck chairs just below the summit or from the large rock clearing on the summit proper. Site was RF quiet.
