There are park alerts in effect.
show Alerts »
  • 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.

Ungulate Threats

Upper Haleakala is now fenced to exclude alien goats and pigs
Upper Haleakalā is now fenced to exclude alien goats, pigs, and deer. Outside this fence, goats have stripped native vegetation to near oblivion. Inside, fenced Haleakalā National Park is a protected sanctuary of native Hawaiʻi’s unique biodiversity.

Invasive non-native ungulates decimate native plants that have evolved without protective spines, tough bark, unpalatable taste, or poison sap. Non-native predators from house cats to ants overwhelm species with no innate fear or defense against predation. Foreign diseases (avian malaria and pox) spread by alien mosquitoes have caused extinction of most native honeycreepers.

Haleakalā's strategy is to fence the park to exclude alien ungulates; remove all populations of feral goats, pigs and deer; and place snares at remote areas to intercept any individual ungulate that penetrates the boundary fence.

The ubiquitous mobility of modern humans, and frequent transport of accompanying biotic organisms (accidental or deliberate) now overwhelms an island ecosystem that evolved in remote isolation. Haleakalā partially thwarts this ecological destruction. The park staff vigorously defends its native Hawaiian biodiversity from invasive aliens.
