You have to get to the TH 827.1 from the 827 Trail which is accessed in the Big Creek Campground. The hike up and down is a nice walk but not much to see. But when you get near the top and at the top, it is worth the hike, lots of scenic creeks. The actual name is Upper Big Creek Trail Loop #827.1.
IMO, not the most scenic hike you can dedicate 4 miles to. My experience may be tainted by the unusually dry year it's been, about half the wooden bridges were spanning dry creek beds. however, if you do decide to hike this trail, be sure to take the side trail to the confluence, where the two rivers merge. this is a great spot for a snack or lunch break.
My dog and I loved this excursion. it was very scenic, and easy. So if you're looking for a challenging hike, this isn't it. The Trail Head is not marked, and there is more than one obvious trail that you can follow either uphill or flat towards the creek.. Once we could see the creek, there were a few access places that were easy to get to and shallow enough for my dog to enjoy playing in and I was able to comfortably sit on the bank and take in the beauty. I would definantly recommend this one for all.
