Know Before You Go:

• Drive up for sunrise or sunset for beautiful colors (if the volcano is not erupting!)

• Bring lots of water and many layers as you'll be at 13,000 feet; altitude sickness is common.

• If you need, restrooms are available at the Visitor Center.

• This is the tallest mountain in the Hawaiian Chain.

• Check out Lake Waiau for a quick hike to an alpine lake.
