From the start of the South trailhead near Pepperwood, our distance totalled JUST UNDER 6 MILES ROUNDTRIP, definitely not 4.4...though I see the map to this uses the other trail start... Just be aware! We do this hike about once a year and love it. VERY clean (good job picking up your trash, everyone!)
Its basically the kitchen sink of hikes...steep stepping, nice smooth forest trail, some safe scrambling, scrub oak, pine forest, desert, shaded creekside trail, bridges, a fun reservoir, beautiful wildflowers, AND OF COURSE THE GORGEOUS WATERFALL! We did this with my brother and sister in law with our combined 5 kids. Our 3 year olds were very very slow and had multiple meltdowns, but we made it...in about 6 miserable hours, but that view is SO worth it! We hike very often, though, and I'm not sure I would recommend this to other familes with young kids, unless you're ready to help carry them! For most, the reservoir is a great destination with plenty of accomplishment.
