I too love this little mountain. If you have nothing to do for a couple hours, go climb it! I have been to the top at least a dozen times and it is always enjoyable. Of course, you may want to avoid this spud in the summer months unless you go early in the morning or in the evening. It can get hot on those SoCal summer days! Great views of Ontario Peak, Cucamonga Peak, and Mt. San Antonio. On clear days you can see the entire inland empire and even Catalina. One of my personal favorites.
