Mount Rubidoux Park

Mount Rubidoux is a mountain just west of downtown in the city of Riverside, California, United States, that has been designated a city park and landmark. The mountain was once a popular Southern California tourist destination and is still the site of the oldest outdoor non-denominational Easter Sunrise service in the United States. Many historic markers and memorials have been placed on the mountain, the most prominent being the cross at the summit dedicated to Father Junípero Serra. A majority of Mt. Rubidoux is owned by the City of Riverside, while 0.43 acres at the peak is owned by Rivers & Lands Conservancy after the cross attracted a potential lawsuit and the city decided to sell it at auction it to a private organization.

The Santa Ana River flows at the base of the mountain, marking the boundary between the city of Riverside and the Rubidoux neighborhood of the City of Jurupa Valley.
