Your Safety


Please remember that you are entering a natural area where you are responsible for your own safety. If you have concerns about any activity or situation, please seek advice from park rangers at the visitor centers. For your safety, it is important to always stay on trail and read and obey all posted signs. In the event of a medical emergency, medical assistance may take up to an hour to arrive from a nearby town so it is important that you come prepared.

The park is divided into two districts with different elevations, features, and climates. For more details on the specifics of these areas visit Kīpahulu District and Summit District,

Watch for Wildlife

It’s exciting to have the opportunity to view wildlife when visiting a National Park and Haleakalā is no different! Several native and non-native bird species call Haleakalā home and are often seen in parking lots and in roadways day and night. Some of these birds are endangered, endemic and only found at the summit of Haleakalā!

Help us protect them by:

  • Driving the speed limit

  • Stopping and waiting for wildlife to cross the road

  • Taking extra caution when driving in inclement weather (wind, rain, fog, etc).

  • Not feeding any wildlife—all the food they need is provided for them in their natural environment!

Hiking Safety

Prepare for the Weather: The wilderness area is remote and experiences unpredictable weather. Temperatures vary from 40-70 degrees Fahrenheit during the day and 30-50 degrees Fahrenheit at night. Plan for rain at all times of year. If it is stormy, winds can exceed 80 miles per hour with temperatures dropping well below freezing.

Terrain: Hiking trails may be steep. Terrain may include loose cinders and/or rocks. Sturdy hiking shoes are highly recommended. Change in altitude can be from a high of 9,780ft to a low of 6,380ft. Due to the soft sandy nature of the trails, plan on spending twice as much time to hike out as to hike in.

Stay On-Trail: Protect fragile species found in the park by staying on the trail! Haleakalā is an on-trail park and all visitors required to stay on designated trails. Staying on trail not only helps fragile habitat but in addition keeps you safe as hiking off trail increases the potential for injury or becoming lost.

Stay Together: When hiking with a group, keep track of each other by staying in sight of one another at all times. If separated wait along the trail, and especially at all trail junctions. Reminder: There is no cell phone service in Haleakalā Crater and it is very limited at trailheads.

Share Your Itinerary with Someone You Trust: Let someone know your itinerary or trip plan and instruct them to contact emergency personnel if you are overdue.

The park's emergency communication center's phone number is 808-985-6170. This number is for emergencies only!

Make sure the person you designate understands that if you are overdue, lost, or injured on the trail, they are your only link to help and should report you overdue if you fail to contact them by a predesignated time.

If Lost: If you become disoriented or lost, attempt to fix your location using a map, compass, and landmarks. If you are unable to locate the trail, stay put! Use a mirror or reflective object to signal for help. Any signal done three times in a series is a universal distress call. Bright colors and reflective materials to attract attention.

If Sick of Injured: If you become ill or injured on the trail and are unable to hike, send someone in your party or a passing hiker for help. Write down and give the messenger your exact location, age, gender, height, weight, and a description of your illness/injury in order to ensure the appropriate emergency response. There is no cell phone service in Haleakalā Crater. Emergency signal devices work in the crater but should not be the only thing you rely on, remember to share your itinerary with someone you trust and instruct them to contact emergency personnel if you are overdue.

Plan for the Best, Prepare for the Worst: Always carry extra food and water, rain gear, and warm clothing in case you have to spend the night out unexpectedly
