If you are looking to get away from it all this is definitely one of the places in Saskatchewan you should take in. Little Bear Lake is approximately 3hours from Saskatoon, close enough that you can go away for a weekend but far enough that the crowds are left behind.
The water in the lake is on a Artesian aquifer and does not rely on other water sources. The water is quite clean and would be worthy of taking some time away from fishing for a quick dip. The lake is quite long and narrow and has a fall at the north end that feeds the Heart Lake. You can leave your boat on the shore and walk a short distance to reach Heart Lake. If you feel like the "rat race" is getting to you, if cell reception is seen as a nuisance and you can't eat another bite of take out this is where you need to go.
