The Salmon Creek trail begins on the south side of the bridge. Follow the trail for about 5 minutes until it comes to a cleared out area (looks like a campsite). Then follow one of the spur trails down to the creek. From there, scramble up the creek to the waterfall. You can find some lovely rocks to have lunch and enjoy the awesome waterfall. The waterfall comes down in two main cascades. A giant boulder at the top separates the creek, nestled precariously (but thankfully, securely) on the ledge.
