The Lower Cedar Creek Trail is a 3-mile out-and-back hike that follows Cedar Creek through a forested canyon with spectacular views of the surrounding peaks and valleys. At mile 1, you will come upon an old hydroelectric plant that supplied electricity to the town of Mackay from 1912-1940. The old wooden pipes, reinforced with metal wiring that delivered the water, follow the creek. Just past the plant, the creek forks, and then it’s just a short 0.2-mile push up to the “hole in the wall” waterfall, which gushes over a million gallons per minute. The trail is generally considered moderate, with some steep sections and rocky terrain.
