Waipio Valley is one of seven valleys, and the only one with a four wheel drive paved road into the valley. When I stayed in the valley, there was no running potable water and the showers were cold. But, it was like nowhere else, especially at night. There is hardly a human sound, only the sounds of animals and birds. When I was there, there were wild horses. The black sand beach is beckoning but trecherous. The most northern valley, Pololu, on the opposite end to Waipio, is uninhabited and you can hike into the valley from the lookout, but the steep trail can be wet, muddy and slippery.
