You can go the the animal zoo in Kamloops and the water slide. They are great places. They had some grizz there last time I was through. I am not sure if the ski hill is open in the summer like the ones in the Okanagan, but you can usually mountain bike up there, with a bike attachment for your gaffer. The hill in the loops is Sunshine mountain I belive. There is also an air show at sometime in the summer that is a great thing for kids. My family went to it all the time when we were younger. They bring out a ton of military planes that are really cool to see. Kelowna is also nice for kids as there are a tone of great beaches. If you are going through the Okanagan, let me know cause I can fill you in on a ton of great places since that is where I grew up and still go all the time to visit family, and we have a 2 yr old daughter that likes to do kid things
