One of my all-time favorite places to visit on this planet is O'heo Gulch.  The waterfalls and freshwater pools of the gulch are part of  the Kīpahulu District of Haleakalā National Park.  They can be accessed by driving 12 miles past the town of Hāna, on the famous Hāna Highway that circumscribes the northeast coast of the island of Maui.  Years ago, some marketing genius decided to call them the "Seven Sacred Pools," but no one seems to call them that anymore.  Unless you want photos with people in them, you need to get there early (better light anyway), and then be prepared to hike into some deep water on slippery rocks with your gear.  Here are a few of my best shots from our visit there last summer.
