Grand Teton National Park is a feast for the eyes -- breathtaking visuals include a 13,770-foot mountain, blue glaciers, and 300-plus bird species. But the park's not just pretty, it's practical. "We offer the activities of a large national park in a manageable size so families can easily get around," says Joan Anzelmo, public affairs chief.
What are the coolest things to do? For an up-close look at wildlife including moose, blue herons, and pelicans, take a half-day trip on a 15-person rubber raft down the Snake River (one of the few national-park rivers that are safe for floating) or schedule a guided horseback or wagon ride through the woods. And 8- to 12-year-olds shouldn't miss the daily 90-minute Junior Ranger programs chock-full of scavenger hunts, short hikes, and habitat games.
