Take a guided tour through Maui to the top of Haleakala, which is an active, but not currently erupting, volcano. Depending on the ages of your family members, you can experience the crater by foot, bicycle, horseback or car. But, if you venture to the top during sunrise, be sure to grab a jacket because it tends to be chilly in the morning! There is a $10 fee per car to enter the park, but that pass is good for three-days, so you can make the most of it. Kids ages 7-12 can become Junior Rangers at Halekala -- stop by the Ranger Station for more details!
