Canyonlands National Park. Both Island in the Sky and the Needles have several short trails great for children. At the Island, kids enjoy peeking through Mesa Arch and climbing the back of the whale at Whale Rock. In the Needles, the Cave Spring Trail, featuring a cowboy camp and prehistoric pictographs, is always a hit. Pothole Point is another popular hike, especially if the potholes are full of water and the creatures that live in these small ecosystems. Adventure pack avail.
