Big Creek Falls is tall plunging waterfall, but when waterfalls like these seem to be a dime a dozen (which is the case in the Pacific Northwest), this had the feeling of more of an average waterfall even though a waterfall like this would've gotten top billing if it was in Southern California. It possessed a thin singular plunge of water dropping 125ft, which we were able to view from a wooden deck providing the only full views that we could safely get.
The steep gorge only allowed us to look down at the waterfall with some trees and foliage growing into the line of sight (though not quite obstructing it to the point of not being able to see a good chunk of the falls as of our last visit - yet). There were other trails leading to other parts of the forest, but we didn't bother doing them so we can't really comment further on where they go. All I know is that I don't think there was a way to the base of the falls. The walk to the falls itself was an easy 0.3 miles each way (or 0.6mi round trip).
The car park for the trailhead of Big Creek Falls is roughly 10 minutes further east from the Curly Creek Falls turnoff along Route 90 (Lewis River Road) in the Gifford Pinchot National Forest. It's about 9 miles east of the Eagle Cliff Bridge and the car park is well signposted.
For geographical context, this waterfall was 84 miles (about 2 hours drive) northeast of Portland or just 45 miles (under 90 minutes drive) north of Cascade Locks.
