A highlight for most visitors to Maui—if not all of Hawaii—is experiencing a guided bike tour down Maui's dormant volcano - Haleakala. You can enjoy this experience in an active way. Bike 26 miles (42 km) from the 6,500' all the way down to the ocean at Paia.
This tour doesn't enter Haleakala National Park, however, you view all the Pre-Dawn colors.
