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.

Many hikers turn around at the boulder field further down Mount Si, wisely avoiding the scramble up the forbidding Haystack Rock in front of you. That's for good reason: Although there is a scrambling route to the top there are also legitimate, ropes-required rock climbing routes, and it's very easy to find yourself on the wrong route. Even if you stay on the scrambling route, the consequences of a fall from the Haystack would be life-changing if not deadly — and coming back down a scrambling route like this is often surprisingly more difficult than getting yourself up.
