Whenever we take our kids out, I almost always have my camera with me. And, as a result, you get to see a little of what we do!
This Is The Place State Park in Salt Lake City is a great place for kids. They have all sorts of activities like train rides, horse rides, garden planting, and other day to day activities that pioneers would have done back in the day. On top of all that, they have a fenced off area where you can let your kids run wild with goats and lambs. They are able to feed, pet, and even wrestle the goats if you'd like to! You can spend hours there and I recommend it if you haven't been there in a while.
