Hi Eileen and Bob, I just came across your topic and thought I'd see if you had done that hike in this part of our beautiful state (I live in OC). I'm looking to hike either Cucamonga Peak or Timber Mountain in the near future (hikingproject.com/trail/700… going up and hiking the Chapman Trail coming down). Date is not yet set. Let me know if you're interested. I'm 60, female and in pretty good hiking and biking shape, prepping for an alps crossing in the spring.
