I-15 with young children

I did that same trip with my then 5 yearold twins two years ago! We stopped in Vegas and rode the log ride, camped at Zion and rode the tram around the park. From Zion we stayed in Salt lake and went to the dinosaur park (kids loved it)! Salt lake to grand Tetons and then on to Yellowstone. While in the parks the girls loved the ranger talks and did some of the jr ranger program. We all loved it so much we did it again last summer and are planning on 2015 again! Enjoy the trip!

Thanks, a nice blog. As mentioned we've traveled that way before, just not in recent memory with young children. Red Rock Canyon East of Las Vegas is a nice turn out for an hour or so, or you can follow the road all the way back to Las Vegas. Indian petroglyphs and lots of ground squirrels. I remember an Indian museum north of St. George just of the freeway. The Island at Salt Lake City is a fun day but hard to find as only one road through a residential area give access. I'm still watching to see if others respond with ideas.

Saw that noone responded to you yet. I was looking at doing that trip and came across a website that chronicles some of the pit stops this family made on I-15. http://pitstopsforkids.com/category/interstate/i-15/
