I've run across lions in Santiago Oaks, Chino Hills, Wood Canyon, Fremont/Weir and Limestone Canyon. All encounters were both very cool and super scary. In Santiago Oaks I was hiking down the 3 B's and took a break to look at the scenery. The sun was setting and it was getting dark. Just in front of me I saw a flicker - a tail with black on the tip and then the lion stood up, turned, saw me and dashed down the hill. What made that encounter scary was I still had to walk down past where the lion dashed off to. The hair stood up on the back of my neck until I got to the car.
In Wood Canyon had a really cool encounter... 5 of us were riding. I was on the left and some were on the right. We all stopped about the same time. I saw a bobcat, my friends stopped because they saw a lion. We came upon a bobcat and lion facing off. By the time I also saw the lion, they both turned and ran. I think we saved the bobcat's life!
Chino Hills has lots of coyotes and bobcats. See them there all the time - basically everytime I ride there. Saw a lion only once... after one of the bad fires... when the park finally opened, riding with friends around 6pm and there he was - just sitting on top of a hill pondering the situation. Thankfully there is safety in numbers!
