The $12.5 million mansion that Dion shares with husband Rene Angelil in Jupiter Island, Fla., has a water park any kid would envy. The backyard boasts a twisty water slide, two Olympic-sized pools and a lazy river.
Turkey Run State Park Indiana's best all-around park (65 miles west of Indianapolis) has a large lodge; hiking trails through deep, wooded ravines; horseback riding; hayrides; and an impressive, year-round lineup of naturalist programming. Sugar Creek at Turkey Run State Park is great for fishing and canoeing (several liveries in the area provide rentals), but not for swimming. If you're itching for a dip, the Olympic-size pool at Turkey Run Inn fits the bill. (765) 597-2635; in.gov/dnr
