This trail is more then 8mi round trip. The trail head entrance this location takes you to starts 1 mile away from tunnel ridge trail. from there it's another 3 mile hike to the tunnel. Glad I went early enough to have time to go the extra 6 miles. Still a nice hike with a great bench view of the nearby valley. The tunnel is creepy but a lot of fun to go through. If you have the time to drive out there then check it out.
this hike was beautiful and super easy to get to. one thing I would like to make clear, not kid friendly. I took two small kids with me, whom have been on plenty of hikes but the trails are about 15 inches wide with huge drop offs to the side. there is also a ton of poison oak, on the bright side the kids can identify it now.
besides that this hike is easy, really beauitful landscapes, i would definitely go again. oh, and there was a fair amount of bear scat so heads up.
1.2 miles just to the trailhead, very easy on the trail with mark well. 8 Miles from where we parked our car and all the way back.. issue was he found lots of ticks on the dogs as well as ourselves. .. but the most exciting part were breathtaking views!!!! really wish we could put pictures on the reviews LOL 5-8-2016
