Conditions
Nēnē (Hawaiian geese) and ʻuaʻu (Hawaiian petrel) are nesting in the park and may land on or frequent park roads, parking lots, and road leading up to the park. Drivers are reminded to drive at the posted speed limits and exercise caution.
Beginning Monday, January 12, 2026 Haleakalā Visitor Center (summit district) parking lot will have limited parking due to a water infrastructure project. Expect traffic delays. The project will last several months.
Due to a high volume of traffic, cars may be temporarily turned around at the gate when capacity is reached. Purchasing a pass online does not guarantee entry at sunset. To ensure timely access, arrive 3 hours before sunset.
As of September 30, 2025, water at Hosmer Campground in the Summit District is shutoff due to a waterline break. Water is available 24-hours at Headquarters Visitor Center one mile up the road. At this point we don't have an estimate for when repairs will be complete.
