Boating
Kootenay Lake is the largest inland lake in BC. It's 156 km (97 mi) long and ranges from 2 km (1.24 mi) to 6 km (3.72 mi) wide, and the water is some of the cleanest and clearest on the planet. There's just nothing like being out in the middle of the lake on a hot day and diving off the boat!
The main boat outlet around here is Jones Boys just up past Ainsworth (about 20 minutes north of Balfour). They sell boats and equipment, service and store boats, and give away tons of great local knowledge.
