Oak Glen is known for its delicious apple cider, homemade apple treats and savory apple butter that have been enjoyed by many for several generations. Oak Glen is located 15 miles east of San Bernardino, at an elevation of 4,734 feet. The area experiences cool summers and winters dusted with snow. The five-mile scenic loop has farms, businesses and ranches that are open year-round.

The original settlers of Oak Glen were the Cahuilla and Serrano tribes. The unique climate and elevation made the area ideal for growing large black acorns, a favorite among locals. The first apple orchard in Oak Glen was opened by Enoch Parrish in 1876, followed by the Wilshire family, who recognized the region’s potential for growing apples.

The apple orchards of Oak Glen produce the Vasquez and King David varieties, which are grown exclusively in the area. Additionally, some heirloom apple varieties such as Arkansas Black and Glen Seedling are not commercially available but can be found exclusively in Oak Glen. While the area is known for producing apples, potatoes and other crops have been grown in Oak Glen since the 1890s.

In 1906, the Rivers brothers established the Los Rios Rancho orchard, which remains in operation today, and is Southern California’s largest historical ranch. Although Oak Glen primarily grew apples for export, it became a boomtown overnight in the 1940s when several farms began to sell apples, apple pies, apple butter and apple cider.

In 1966, a wildland trust came to Oak Glen, offering a picnic area, hiking trails and many activities that made the area more appealing to visitors. The orchards draw more than 300,000 visitors annually who come to pick apples and enjoy homemade pies and fresh pressed apple cider.

Today, Oak Glen is home to hundreds of residents and continues to be a popular destination with a rich history.
