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.
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.

Bamboo is one of the non-native plants you will see when you hike the Pīpīwai Trail in the Kīpahulu District of Haleakalā National Park. The extensive bamboo forest provides a unique array of sights and sounds along the trail. More...
