Fire road hike through old and new growth. 1400 feet of climb with great views. From the orange gate off of Hwy 99 W you will start long gradule uphill climb on the 540 road past Cronemiller Lake where you pick up the 500 road. Follow this road up a steeper climp to the summit or junction of the 500, 560 and 580 road. At this point take the 580 or Davies road which goes up and down past the "quary swim hole" and up to the Lewisburg Saddle where there is another orange gate and port-a-john. At this point you pick back up the 500 or Nettleton road and follow it up to the summit junction of the 500 and 5010 road. Stay left and follow the 500 road back down to the 500, 560 and 580 road junction, then left on the 500 road and follow the road back down past the lake and back to your car. Total climbing gain is approx. 1470 ft.
One of my favorite trails! Especially nice if you take some of the little side loops like the Old Growth Trail and the Vineyard Mountain Trail.
Easy, mellow, and nice ground to walk on! Highly suggest this hike! Especially if you're looking for an easy one!
Great hike and workout. Not real well marked for the amount of trails that can be accessed up here. Can get turned around pretty easy if you don't pay attention. I was second guessing myself a couple of times and made the correct turns to get back to the parking area. Overall a great area, not a ton scenic views.
This trail is a great workout but a little light on the scenery. At the time I was intending to hike the smaller loop but must have failed to get on the right trail, which leads me to my next point. The trail is not very well marked. Definitely worth seeing but take someone with you who has been there before. If it were a Ducks hiking trail it would have been better marked :p
