 Atyoida bisulcata were plentiful in the stream and were seen rolling and tumbling down the falls and into the churning waters at the fall's base.

Visually, this is a spectacular waterfall and is one of the island's few waterfalls that can be seen from the road. It flows year round and therefore is not seasonal. Most of the time it falls in a double cascade but the two sides may become one after a heavy rain.
There is a highway overlook which provides a panoramic view of the 40 feet (12.2 m) wide falls and the valley below. The best time of day to see the falls is in full sunlight when the water sparkles the most. If the day is cloudy the view is less spectacular.

View from highway

The highway parking lot offers an excellent overview of the double 'Opaeka'a Falls. The tops of the Makeleha Mountains can be seen in the background while tropical birds soar through the valley below. The best view of the falls is seen by taking the sidewalk past the parking lot and walking toward the bridge. The Wailua River

There are rumors that there is an unkempt 0.6 mile (0.965604 km) hunter trail leading to the bottom, where there is access to the large, deep pool at the bottom of the falls. Many deny the existence of the trail due to the danger in following these trails.

Directions

. There are no state-maintained trails to either the top or the bottom of the waterfall from the Kuamo'o Road overlook.
