Two weekends ago we took the kids to heralds provincial park just south of salmon-arm B.C on Hwy 1 transcanada. The park is very nicely laid out with lots of privacy between campsites. There are out houses with flush toilets and shower houses.
We had a great time and would definetly return here again! We paid $30. Per night More photo's below....
Here is an example of a campsite at Heralds park. Some sites have Margaret Falls stream running behind them with hiking trail. If you plan on reserving a site at heralds my personal top campsite would be #72 as it is only steps away from the beach. Or sites 70,68,66,64,63,62,59,58,57,53,52, as they all have Margaret falls running behind them.
Here is the beach not very sandy for making sand castles but great for swimming!
