Oak Glen is located in the foothills of the San Bernardino Mountains. Most of Oak glen is located at 4000 ft above sea level or higher. This elevation gives us the cold weather that Apple trees need to enter a dormancy period that sets the annual apple production cycle in motion. Oak Glen has many businesses and residential properties that stretch a six mile length of road winding though the hills. All along the road you will see apple growing operations and businesses that allow one to experience the rustic charm that envelopes all of Oak Glen.
