1. Haleakala Crater is a massive volcanic depression, situated at the summit of Maui’s highest peak, Haleakala. The name Kapalaoa is sometimes used for this crater as well. It stretches over seven miles wide and 2,600 feet deep. The crater is a result of the volcanic eruptions that took place some 500-800 years ago. Today, it’s one of Maui’s top attractions, drawing in over a million visitors per year. Visitors can witness the crater’s ever-changing weather conditions, from clear blue skies to thick clouds and even sudden snowfall.

2. The Haleakala National Park is open daily, year-round, from 7 a.m. to sunset, while the visitor center’s operating hours are 8 a.m. to 3 p.m. The park’s phone number is (808) 572-4400.

3. To enter the Haleakala National Park, visitors need to purchase a pass that costs $25 per private vehicle, $12 per individual, $20 per motorcycle, and $30 for trios. The pass allows entrance for three days. Visitors can purchase the pass either online or at the park’s entrance. It’s essential to note that there’s a limited number of vehicles that are allowed to enter the park per day, and reservations are required. The best way to get to the summit is by car, and guided tour buses are also an option.
