About 0.24 mile below the summit of Mount Si, this viewpoint on the Mt. Si Trail offers sweeping views of the Snoqualmie Valley through the trees. There are some boulders in the way of the view, but some will scramble around to see the view. Be careful, as veering off trail can be unsafe. The best views are close, at the summit!

The scramble up and down the final pitch is exposed and dangerous. Be careful, go slow and follow the “three points of contact” rule.

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.

The Talus Loop Trail offers a relatively quiet experience on the slopes of Mount Si, while still offering some beautiful views. It also serves as a connector between the Mount Si trails and those on Teneriffe Peak.

The Kamikaze Trail that links Teneriffe Falls to the summit of Mount Teneriffe is as steep as the name suggests. It's also fairly easy to lose the trail at points.

Take care on the final push to the summit of Mount Teneriffe; it's a steep, rocky scramble. You are rewarded with stunning views of the valley below, plus of course the surrounding peaks. Look for the distinctive triangle of Mailbox Peak nearby and, on clear days, Mount Rainier in the distance.
