4runnerguy,
The list I gave you is just a rough outline of things to consider. As I don't know your hiking and biking capabilities, these suggestions may be fine or turfed out. I have a few more comments:
1) We use the Trailforks app for info on over 7000 MTB trails in BC and oh course a lot of other areas.
2) If you are interested in a few southern interior PP's head south from Vernon on #6 to New Denver/ Slocan and hike in Valhalla PP.
3)South to Nelson. MTB
4)Head up lake and drive up to Kokanee Glacier PP and hike the many trails.
5)Head to Fernie MTB.
6) Drive to Invermere, past Panarama ski area and go to the end of the road. Hike up to the ridge. Fabulous views of the Jumbo Glacier.
7) Drive to Radium, turn left and drive to trailhead for the Lake of the Hanging Glacier hike. Free boondocking at trailhead.
8) North to Golden and hike Bugaboos.
9) Back to Golden for MTB and Hwy#1.
10) If you haven't been there before stop off at Waterton NP which shares the border with Glacier NP(USA) and hike for a week.
Head home and sleep for 11 months.
I will try to answer any questions you have if you are interested.
Dave
