Fodor's Expert Review Oheo Gulch
One branch of Haleakala National Park runs down the mountain from the crater and reaches the sea here, 12 miles past Hana at mile marker 42 on the Hana Highway, where a basalt-lined stream cascades from one pool to the next. Some tour guides still incorrectly call this area Seven Sacred Pools, but in truth there are more than seven, and they've never been considered sacred.
While you may be tempted to take a dip, know that the pools are often closed because of landslides and flash flooding. If you see a closure notice, take it seriously, as people have died here.
The place gets crowded, as most people who drive the Hana Highway make this their last stop. It's best to get here early to soak up the solace of these waterfalls. The $30 entrance fee per car is good for three days and includes entry to Haleakala's Summit District.
