The Heber Valley is beautiful and Jordanelle State Park is a great place to stay while you explore the area. It's a lovely, clean, well run state park that sits on a nice reservoir that is perfect for boating. I stayed here with my children at the end of June and while day time temps were high, the lake was cool and clean, the nights cooled off quickly, and there were no bugs to keep us from enjoying our s'mores by the fire. The sites are nicely spaced, there is a great playground, and plenty of campground trails to walk the dog.
