I arrived at the parking lot around 7:30 am and were able to find a parking by the side of the road. the parking lot was full as early as that time and the side road has been lined up as well. the weather was great that day and was able to feel the cold breeze throughout the my hike all the way to the peak. I met lots of hikers and some of them were even wearing their Halloween costumes and made the hike more fun. Social distancing was very much observed. Most hikers were heading for the Cucamonga peak and I was able to have Ontario peak for myself for half an hour. There were group of hikers who were camping as well and dogs were very friendly. The weather was perfect for that day, it was a little windy but it helped with hike. I was able to finish my hike for a total of 7 hours. the on top was beautiful and very peaceful as well.
