WorldYellow In detail

Waimanu Valley

Similar to many other great valleys of Hawaii, also Waimanu Valley is covered with lush vegetation. Even the steep walls of the canyon are covered with green plants.

This is a remote valley and not too many visitors come here. In fact, it is not easy to come here. There are no official roads although one can enter the valley with a good and powerful car if the driver is not afraid of extreme steeps.

Waimanu Valley is rich with waterfalls and almost all of them are true giants regarding the height, many have fine, cool pools at their base. At the same time, one could easily get lost in the bush and it is not always easy to tell which waterfall is which.

On the western side of the giant Waimany Valley is a side valley that has formed on the slopes of the extinct Kohala Volcano. This valley resembles a giant, deep bowl with very steep, almost 800 m tall walls. This bowl opens towards the north-eastern side, the main part of Waimanu Valley.


Along the steep walls of this giant bowl flow several very tall waterfalls. After the rain the number and size of waterfalls increases but even in dry time at least one – the northernmost of the streams is flowing.

As the northernmost stream is richer with water, it has eroded the bed creating multiple smaller plunges and plunge pools. It has at least eight closely located drops.

Further to the south several more (at least three) streams of waterfalls form after rains. These falls do not have such plunge pools anymore.

Some videos (first 17 seconds) show that only the more powerful stream is flowing, while in other videos all four falls are active.

Wonders of Hawaii

The Hawaiian Islands belong to the most remote islands in the world. Hawaii is characterized by a tropical climate, mountainous relief, volcanism, and isolation. If compared to most islands in the Pacific, several Hawaiian Islands have comparatively large landmasses. All these factors have led to the development of numerous impressive and unique natural attractions and some impressive monuments of culture.

Some of the most fascinating and awe-inspiring natural monuments are waterfalls or locations where a river abruptly changes its elevation.
