Good moderate trail with some good views at the top. I recommend parking at the lot at the bottom of Keller Peak Rd rather than the top which the directions take you to. My activity tracker clocked 10.75 miles round trip. Good hike with you dog. There aren't any sharp rocks or boulder scrambles.

This is a great trail with some shade and a decent uphill climb. The trail is about 4.3 miles to a parking lot and if you want to continue to Keller Peak it's another 1.5 miles. Round trip about 12 miles. Not a difficult hike and the views are amazing, especially at Keller Peak. I completed the trip up and back in 4 hours and 20 minutes.

I definitely wouldn't use the words "a lot" to describe the quantity of shade on this trail. It was HOT. Gnats were out like crazy, and there weren't any even remotely impressive views. Good exercise but we probably won't be doing this one again.

A really beautiful, shady trail that climbs the western flank of Keller Peak through a black oak forest community. The grade is pretty mild on most of the trail and the views that open up at the upper elevations are fantastic.
