It was confusing to me at first, but there are in fact two Hillcrest estates in the Cape Town area... Hillcrest, the berry farm, and Hillcrest, the producer of fine Cape wines. The former is located just outside of Stellenbosch and the latter on the outskirts of Durbanville.
This photo is of a small secluded function venue at Hillcrest that's often used for corporate events, weddings, and other parties.
