- At only 28 feet, Yacolt Falls isn’t the biggest waterfall in the area, but it’s delightfully complex. The waterfall is also, perhaps more correctly, known as Big Tree Falls. There’s a unique “footdrawbridge” just below the waterfall. This is tied back in the winter, but is usually put in place in the summer so you can make a loop hike. Come here early on a weekday for a little solitude with your camera. The splash pool is a common swimming hole late on summer afternoons.
