Drumheller Dinosaur museum is very interesting. It's about 2 hours drive east of Calgary, in the Alberta Badlands. Interesting scenery too, and good RV campsites. I've also camped at the Bow Valley Provincial Park , and Tunnel Mountain in Banff. Both are government run and busy. So book early if you can . Mount Kidd RV park is popular, but again you must book early . The Icefields Parkway between Banff and Jasper is a beautiful drive an a must visit. Lots of wildlife and amazing scenery. There's lots of campsites, but again very busy . Most of the Provincial and National Parks campsites do have sites that are on a first-come , first-served basis, but you need to arrive early. June is a good time to visit. Not as busy as July and August. Bring a few warm clothes . The mountains can get chilly at night. I have seen snow in Calgary in June too !
