Lying peacefully in east Orange alongside the Santiago Creek, the 1,269-acre Santiago Oaks Regional park is a nature lover's paradise. This secluded refuge offers hikers, bikers and equestrians the natural charm of mountain vistas, an orange grove, a meandering creek and a mature forest of many different species of trees. Wildlife abounds and a series of interconnecting trails leads through shady groves and to a lookout that features an awe-inspiring view of Orange and the surrounding foothills.

On March 11, 2007, a vegetation fire started near the Windy Ridge Toll Plaza of the 241 Toll Road. Fueled by heavy winds and dry vegetation, the fire spread in a southwesterly direction, burning 2,036 acres.

Starting in March of 2011, nearly 200 new coastal live oaks were planted at the park in a park restoration project that is also a mitigation measure being fulfilled by OC Waste & Recycling.

Activities

Santiago Oaks Regional Park provides the visitor with a sense of removal from the urbanized environment. The native plant life coupled with the specimen forest in the Rinker area provides an atmosphere of relaxation and serenity. The park has a series of interconnecting trails suitable for equestrians, hikers and mountain bikes. The park trails also provide access to the Anaheim Hills Trail System and offer spectacular views of northern Orange County.

The nature center, which opened in the summer of 1981, offers exhibits and programs on various natural history topics. Park Rangers provide a variety of interpretive activities including nature walks, slide programs and films. Group programs are provided for a nominal fee and must be scheduled at least two weeks in advance. Nature programs for the general public are conducted on weekends dependent upon staff and volunteer availability.
