This is a very worthwhile trail, but be advised that its "moderate" rating applies only if you average out the flat & easy stretches with the steep & rocky climbs! Previous reviews are right that much of the exertion in this one is in the steady (sometimes steep) climb up and having to watch your footing both up and down due to all the roots and rocks. But for scenery and fun? Go by all means! There are a few fun footbridges, stone steps, creek beds to cross and climb, and the river, pools, and mini-falls that you're treated to along almost the entire way. It took me about 3.25 hrs to go up with rest stops and photo stops along the way and about 1.75 on the way down. I'd probably have dallied more if I had started earlier but the light was fading fast. This would be a great trail for warmer weather if you bring Tevas, lunch, and swimsuits, but allow for having plenty of drinks and taking your time. Frankly, I'd go back just for some of the smaller midway cascades, but having seen the top, I'd be tempted to finish it anyway! I've described this trail all weekend as a kick-*ss trail: as in it's THAT pretty and it will kick yours!
