The roads and restrooms in the park are open 24 hours a day. National Park Haleakala Summit and the Kipahulu coast. There is no direct road between the two but they can both be reached from Kahului.
Sky watching is one of the most popular pastimes at the park.
You can rent a pair of binoculars at an island dive shop and watch the planets, stars and moons after dark. Even with cloudy skies during the day, you can see rainbows, moonbows and halos around your shadow. On the drive to Haleakala Summit, you will climb from sea level to 10,000 feet in just 37 miles and at the summit will be offered a view that extends for more than a hundred miles. Sunrise is the most popular time to go as the view is usually free of clouds, but the best time for photos is in the afternoon. The weather at the summit is unpredictable, so be prepared.
