Haleakala observatorySummit Area

The summit of Haleakala is an island atop a volcanic island, with its own distinctive climate and habitats.  Its cinder desert is sometimes frozen and seemingly barren, Yet a variety of creatures and unique plants like the  ‘ahinahina (Silversword) have adapted to the summit’s extremes.

Despite the contrasts to seashores of Maui, the summit is connected to the rest of the island in critical ways. The upper slopes capture moisture to nourish the rain forest of Kipahulu and feed the streams and waterfalls in the valleys.  The summit also preserves portions of the original Hawai’i, including native vegetation and evidence of the early inhabitants.

  • You are responsible for your own safety
  • Be prepared for extreme and sudden weather changes.  Dress in layers and bring rain gear.
  • Be alert for symptoms of altitude sickness: headache, nausea, dizziness, shortness of breath.  If you get altitude sickness, have help getting lower   in altitude, drink lots of water, and call 911. If you’re near a park employee or the visitor center, ask them for assistance as well.
  • Protect yourself from the sun.  Cover up, use sunscreen, wear a hat and glasses. In cold weather, it’s easy to forget how powerful the sun is, especially at this altitude.


  • Respect the ‘aina (land).  Many people consider the park lands to be sacred. Be mindful.
  • Stay on designated trails.  Off-trail hiking can kill unseen plants and animals or destroy cultural resources.
  • Leave things as you find them, including rocks, which can possibly animal or plant homes.

  • Clean boots of dirt and seeds.
  • Camp in designated areas only, and get a permit if required.
