The area of Devore is an unincorporated community in San Bernardino County, at the southern entrance point of the Cajon Pass. It is located roughly near where I-15 and I-215 come together, and is the home of the Glen Helen Pavilion and Amphitheater, the largest amphitheater in North America. Sycamore Valley Ranch, formerly known as Sycamore Grove, was the first camp of Mormon Pioneers in the region, and is located at Glen Helen Regional Park. It is California State Landmark Number 573.
