Short but sweet! This trail will give you a great leg workout! Almost no shade so bring extra sunscreen! Lots of uphill on the first half and then lots of downhill on the return! Very challenging trail! Took me 3.5 hours with no breaks.

It’s literally nothing but walking in zig zags uphill.

Great hike/workout. I did this hike in early June when the grass was no longer green but some wildflowers were still blooming. The trail is mostly exposed, carry sun protection/hat. It was pretty windy on the day I went so I did not feel the sun as much. It is a fire road all throughout and the gravel can make it slippery, wear good shoes and/or carry hiking sticks. Great views from the top. I was the only person on the trail except for some mountain bikers passing by. Enjoy!
