After now visiting 50 of the 59 USA National Parks (its a long way from Australia!) Haleakala has jumped into equal No. 1 in our National Parks favouritism, and this morning at the top of the mountain, with an early morning sunrise, followed by a hike down the Sliding Sands Trail, is why. Probably the most other-worldly location I have ever visited. February 2013 PS can you guess whats equal No. 1?
