Haleakala National Park on Maui, Hawaii, provides an amazing volcanic crater experience that has you thinking you are on the lunar landscape. A less known way of accessing this spectacular park is the “backway” by the Kipahulu area, about 12 miles called Oheo Gulch or by the popular name “Seven Sacred Pools.”
Gorgeous, wild and an amazing place to hike and paint, you can take the 0.5m loop to the oceanside “sacred pools,” or make the 4-mile round trip trek to the 400-ft Waimoku Falls. 
Pīpīwai trail follows the stream which courses through the ‘Ohe’o Gulch, through an amazing Bamboo Forest. The falls are tall and stunning, struck me like the “Yosemite Falls” of Maui.
On a recent trip to the Hawaiian Islands, we stayed close to this park entrance, at a sustainable Bamboo Farm called “Whispering WInds.” My husband consults for sustainable technologies, so we meet many wonderful, inspiring companies and entrepreneurs. The farms owners have also been involved with the federal Natural Resources Conservation Service Forest Stewardship Program , to reforest their 180-acre property with tropical and native trees, planting tropical timber like mahogany, teak and monkeypod, as well as Polynesian and native trees including koa, kamani, alahee and kukui.
