This is just a question of curiosity. There a mountain in San Diego County called Margarita Peak that is easily one of San Diego County's greatest hidden secrets. It's 3100 foot summit allows you see five whole counties from the top: San Diego, Riverside, Orange, San Bernandino, and Los Angeles. The 360-degree panoramic views are absolutely breathtaking! Coastal views from San Diego to San Pedro, mountain views of San Jacinto, San Gabriel, Cuyamaca, El Cajon Mountain, and much, much more. Has anybody heard of or hiked this awesome mountain before?
