Make this your first stop. Rangers and volunteers can advise you about volcanic activity, air quality, road closures and hiking trail conditions. Interactive museum exhibits are small but family friendly, and will teach even science-savvy adults a lot about the park's delicate ecosystem and Hawaiian heritage. Pick up fun junior ranger program activity books for your kids before leaving.
Geology talks are given twice daily by the outdoor signboards, where ranger-led hikes and other activities are posted. A well-stocked nonprofit bookshop inside the visitor center sells souvenirs, rain ponchos, walking sticks and flashlights. Wheelchairs are free to borrow upon request. There are restrooms and a payphone.
