Hidden Canyon is tucked off Serrano Avenue near Santiago Oaks Regional Park, making it the most secluded guard-gated community in Anaheim Hills. Custom and semi-custom estates range from 4,100 to over 11,000 square feet on some of the largest private lots in Orange County, with prices from $3 million to $6 million-plus. Buyers here prioritize architectural distinction, acreage, and genuine separation from surrounding neighborhoods.
