These falls are found at the end of the Pipiwai trail inside Haleakala National Park. They’re at the end of a 2 mile hike with a gently up slope. The water falls 400 feet and to get them all in you need a wide angle lens and be some distance away.
The Pipiwai Trail in the Haleakala National Park at Oheo Gulch has a section of dense Bamboo. The park has tried to make the hike a little easier by putting in steps seen here and walkways in many of the wet and muddy areas.
