Does anyone no the riding area off the 91 fwy and the 15 fwy. Drove by there the other day during the day and seen people riding around.

 

Could you be more specific? The 15 & 91 meet in West Riverside/Corona. I grew up riding dirt bike and mountain bike in this area. Use to be great, but has seen a lot of development. Not sure what is left anymore. Riverside County has a no off-road riding ordinance, so you are going to have to be stealthy if you are going to ride anywhere!

 

I was heading west on the 91 Fwy, about 3miles before the 15 fwy on the left hand side you could see the trails and people riding there.

 

That is not a legal riding area. I have been up there years ago. There is a fence up but some areas the fence is gone now. Lots of hills, but kind of boring. It may belong to the gravel pit/asphalt plant that is digging along the west face of those hills.
