A friend and I hiked this trail this past weekend and camped over Saturday night. 10/22-23/2016. Leaves are starting to change however next weekend should probably be a better weekend for fall foliage. Loots of woods hiking with 3 streams crossed. Only had one bluff on this hike and no arches; unless we completely missed them. A few huge rock formations and cave structures. Had a bout a mile on a gravel road with traffic and crossed a freeway by bridge road. Like I mentioned not a great trek if looking for a lot of bluff views or rock arches however fairly challenging with a couple difficult challenging. path climbs.
Great trail and the views are terrific. The only downside is that this trail is very popular, so there are usually lots of people. That's not always a bad thing, but if you're looking for a little solitude while hiking, you probably won't find it here. Still, this is a nice hike.
Trailhead immediately across from start of Tunnel Road. Park alongside road in small pull off area on Tunnel Road side. Switch back down from trailhead to easy hike along stream. Well marked trail. Best to go after good rain when stream and couple waterfalls flow. Natural Bridge is cavarn like. Good add on hike to other hikes in area. see pics at instagram.com/hikingandexploring
