Orange Hills - Orange Hills Trail Professional Review and Guide
"One of Orange County’s oldest settlements, incorporated in 1888, the City of Orange now numbers some 140,000 residents. How do all those people fit into the city’s 27 square miles? Get an answer to that question by taking a hike to a trio of promontories in the Orange Hills, where summit vistas include most of the city’s residences, as well as what remains of the natural environment in the city and county of Orange. A mile-long ridgetop parkland, which appears as Santiago Oaks Regional Park on most maps and El Modena Open Space on a few, rises above the city and offers the hiker a rigorous hill-climb over slopes blanketed with thick clumps sage and prickly-pear cactus. Considering the highest summit in these hills is but 806 feet in elevation, clear-day vistas are mighty good, particularly to the west across northern Orange County to the LA basin and beyond, and north toward the San Gabriel Mountains."
