  • O`heo Stream and Pools Closed

    The O`heo stream, located along the Pipiwai Trail, remains closed due to high water and damaged stream monitoring equipment. Visitors are advised to abide by posted “stream closed” signs and the direction of park staff.

  • For your safety

    The Summit and Kīpahulu Districts are remote. An ambulance can take up to 45 minutes to arrive at either district from the nearest town. People with respiratory or other medical conditions should also be aware that the summit of Haleakalā is at 10,000 ft.

  • Drive cautiously - Endangered birds land on roadway

    Nēnē (Hawaiian geese) are nesting in the park and may land on or frequent park roads and parking lots. Drivers are reminded to drive at the posted speed limits and exercise caution.

Natural Features & Ecosystems

Crater rainbow and shrubland
A rainbow hangs low in the mist over native shrubland in the crater. The crater itself contains a diversity of high-elevation ecosystems, from the dry aeolian cinder desert near the summit to mesic rainforest near Paliku Cabin.

Ohia lehua in gulch

'Ohia lehua (Metrosideros polymorpha) are a common tree in Hawaiian rainforest and, occasionally, shrubland. The bright red flowers provide nectar for native honeycreepers.

Haleakalā, rising from the sea to a 10,023 foot summit, and exposed to both the windward moist tradewinds and leeward drying air, has a variety of natural ecosystems. Wind, rain, temperature and altitude all play a role in shaping each zone, as well as bringing plants and animals here. Visit the Plant Communities page for more information on the diverse plants in each ecosystem you might see.

The alpine aeolian zone seems barren. The porous, rocky, dry surface has wide temperature range between day and night. Only a few species survive this tough environment. Silverswords stand out in this open landscape.

Subalpine shrublands cover broad areas below the alpine zone. Native shrubs like pukiawe, mamane, ohelo and pilo are dominant. Nēnē, the native Hawaiian goose, are locally conspicuous in the shrublands.

Lower, on the windward slopes with rainfall of 120 to 400 inches annually, rainforest prevails. Above 3,000 feet elevation the rainforest is largely native species with ʻōhiʻa and koa forming a closed canopy. Here, native Hawaiian honeycreepers sip nectar from native trees and flowers.

 
Reynoldsia dry forest

A remnant Reynoldsia sandwicensis in a dry gulch on the leeward slopes of Haleakala. Both bark and seedlings are eaten by feral ungulates; as a result, few of these trees remain on Maui.

Below the shrub zone dry forest occupies the drier leeward slopes, with less than 60 inches of rain. Fire and alien ungulates have devastated most of Maui's dry forest. Only small patches are found within the park.

The ʻOheʻo stream ecosystem crosses several life zones. ʻOheʻo stream, with its entire length within the national park is one of very few completely natural riparian habitats in Hawaiʻi. Native fish and shrimp are stream residents.

Did You Know?

These freshwater pools are fed by streams originating in the rainforest higher up the mountain, so the water flow changes daily.

The Kīpahulu District of Haleakalā National Park is home to many freshwater pools that were created as the Pīpīwai, Palikea, and ʻOheʻo streams carried water down the mountain from the rainforest above. More...
