Hike Description:

Follow the Twin Falls Trail as it heads upstream along South Fork Snoqualmie River. At 3/4 mile, there is a distant overlook of the falls, but the view isn't great.

At 1.1 miles, a side path on the left leads down to the view of the lowest section of the falls. At 135 feet, it is quite impressive. The water level was low when we visited, but that exposed more of the beautiful rock that the water falls down.

Head back up and turn right on the main trail to cross a bridge where the middle drop is visible.

A little further up is a view of the upper drop, but it is blocked by foliage. We found a scramble path that led down to the base of the upper drop, but had to use a rope to get all the way down.
