Weather in the Summit Area is unpredictable and ever-changing. Hikers must be properly prepared for high altitudes and cold, rainy conditions. Temperatures commonly range between 30 to 65 degrees F (-1 to +18 degrees C), and can reach below freezing at any time with the wind-chill factor. Soft cinder trails create hiking conditions similiar to walking on a beach in some areas. 15 minutes hiking down + 30 minutes up = 45 minute hike. When beginning your hike on a downward slope, allow for twice the time hiking to get out, e.g. Pregnant women and people with heart or respiratory conditions should consult their doctor before visiting and hiking in the Summit Area. Be on guard for symptoms: nausea, headache, dizziness, and shortness of breath. Trails are strenuous in the Summit Area because the high-elevation causes a lower concentration of oxygen in each breath. You can hike in the native shrubland, looking for native forest birds and endemic plants, or in the aeolian cinder desert, exploring the geologic history of the volcano. With over 30 miles (48 km) of hiking trails, that range from just 10 minutes to multi-day overnight trips, there are many options in the Summit District. Pets of any other kind are prohibited on all trails. Riders, commerical operators, and owners are responsible for the removal of dead or injured stock within 72 hours. No group may have more than 12 pack animals.

All waste produced by pack animals must be removed from parking areas and trailheads. Horses, mules, and donkeys are permitted as pack animals on the Keoneheʻeheʻe Trail, Halemauʻu Trail, Supply Trail, and the Kīpahulu horse trail from Hwy 31 to the Palikea Overlook. No food, supplies, or gas are available in the park. If your group is larger than 12 you will need to split into two or more groups and separate each group by 30 minutes on the trail. Due to the fragile nature of Hawaiian ecosystems, it is required by law that hikers stay on marked trails. Enjoy the great outdoors on a variety of trails in the two dramatically different districts. There is no better way to experience Haleakalā National Park than on your own two feet. To the left of the trail is the Ko'olau Gap to the right of the trail is the crater floor.
