"It could not have been a more spectacular day to hike Old Greyback. It was sunny but crisp and cool. We arrived at 6:30 am and already had to park in the bigger lot. We were on our way by 6:45am. That first mile up from the vivian creek trailhead is no joke but it was even worse thinking that would be one of our last miles down! We took it slow and were on top of the summit by 1:20pm. It was so nice! Bright blue sky, great views, slight breeze. We ate lunch and headed back down around 2:20pm. We were lucky to see some beautiful deer around basecamp.

We are attempting to summit again this weekend. :) " - Parker33845, Mar 4, 2017
"Best hike in So Cal. Just gorgeous. And the well engineered makes the trek seem so much easier. I'll have to be back to camp on top someday. Oh, and that's my first peak list down (6/6.)" - JustinB, Aug 5, 2016
