Two great places!
Patty, the lady that looked after Bailey and our house, told me she was taking Bailey over to the Kootenay Canal for walks while she was here. I checked the Kootenay Canal out and what a fine place for power walking! It is right in the open so no danger of wild animals or jerks. It is nice and flat, the scenery is just breath taking and it is easy to get a tan. The Kootenay Canal is just an 8 minute drive from my house and a good 50 minute power walk.
The other great place for power walking is the old rail beds off highway 6 along the Slocan River. That place is also nice and flat. The rail beds go a very long way so you can make your walk as long or as short as you choose. The scenery is also gorgeous along the river but I do think that there is the possibility of meeting up with wild animals or jerks but there are quite a few homes along the way so it should be safe enough. Best to go with a friend on that walk.
