Do you have any water craft? If not you could rent some and go to Lake Powell in Bullfrog,Utah. There is boating,jet skiing, swimming, fishing,sun bathing, hiking, inner tubing, and cliff jumprobably probably enjoyed the jet skiing the most.Plus there's great gift shops and restaraunts all around it. And there's a campground about 1 mile from it that allows trucks,campers,tents, just about anything that you can sleep in. If your not much of the hot weather type you could go to Colorado, which has rafting,horseback riding, fishing,swiming,hiking,biking,musems,amusment parks, and a LOT more. I hope this helped
