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. Mount Rubidoux is an important landmark and valued asset to the people of Riverside. On April 12, 2009, the 100th anniversary of the Easter Sunrise service was held at the top of Mount Rubidoux. Mount Rubidoux Park is open from dawn until dusk. It covers 161 acres (0.65 km2; 0.252 sq mi) and features 3.5 miles (5.6 km) of paved roads and several dirt hiking trails. The park is closed to vehicular traffic, but improvements in 2009 boosted the number of daily walkers, joggers, and bicyclists.
