Umauma Falls, Triple waterfall in Hamakua Coast, Hawaii.
Umauma Falls is a triple waterfall on the Big Island of Hawaii, where water descends in three separate cascades over dark volcanic rock. Each cascade drops into a deep pool, and the surrounding canyon walls are covered in dense tropical vegetation.
The falls took shape millions of years ago when Mauna Kea rose from the Pacific and built up layers of basalt rock. Over time, the Umauma River carved through those layers to create the stepped descent visible today.
The name Umauma comes from the Hawaiian language and refers to the river that feeds the falls. Visitors walking the path can see how water cuts through layers of dark basalt, a pattern that defines much of this stretch of the Hamakua Coast.
The falls are located within the World Botanical Gardens, where a paved path leads to the viewing area. The path can get slippery after rain, so sturdy footwear is a good idea before heading out.
All three cascades can be seen at the same time from a single viewpoint, which is uncommon for a waterfall of this type. This arrangement lets visitors take in the full drop from top to bottom in one glance.
