According to the Northwest Waterfall Survey, Teneriffe Falls, formerly known as Kamikaze Falls, is 414 feet (126 m) tall. However it falls in several tiers, with the highest measuring 226 feet (69 m) — and some parts of it are obscured by the forest and fallen logs.

Stop a moment to enjoy the cascading waters of Lower Twin Falls. This makes a lovely stopping point on its own, but you can continue hiking to another viewpoint overlooking Upper Twin Falls.

It's worth continuing to Upper Twin Falls, which gives you beautiful, unobstructed views of the cascading water. Although the trail does continue onward from here it departs the water and is more exposed to the road. So for many hikers, this is the logical turnaround point.
