Living in Riverside, you can't miss the cross that is on top of Mount Rubidoux. I have hiked the road up to there countless times. When I am training, I will ride from my house to Mount Rubidoux and up to the top and then back home finishing with the climb up to my house from Victoria up to Lake Matthew's.
A Cross has been at the top since 1907 when the first one was installed after Frank Miller had a graded road put in that went to the top. He originally planned to develop the property for expensive homes, but that did not work out. In 1909 the first Easter Sunrise Service was held at the top and it has been held every year since. The Boy Scouts started a path lighting service project for the Sunrise Service in 1922. The cross that is at the top now, was dedicated in 1959 as the Serra Cross. President Taft was here in October 1909 and dedicated a second plaque to Father Serra.
There are other plaques on the mount commemorating the Boy Scouts, Col Shunzo Kido, Frank Miller, and the original dedication plaque that named it Huntington Park.
Now it is a Riverside City Park, Mount Rubidoux Park. Great views of Riverside and the surrounding area can be found at the top. Every year there are fireworks from the top. It is a landmark and if you are out here, worth the walk.
Thanks for looking.
