8/4/18 - Came here with my boyfriend and 6month old pup. It was hard to find the entrance but we lucked out by seeing another couple Park and climb up. If you see the Lake Hills sign that’s where you begin your hike. I’ve lived in Corona for 14 years and the first time hiking here so it was beautiful! Didn’t know Corona had hidden treasures. This hike was not so long and easy to follow with the colorful graffiti guiding you.
