Offered as an exclusive add-on opportunity to MLS PTP2600219 (15351 Isla Vista Road, Jamul, CA 91935), this expansive 20.75-acre parcel of raw land presents a rare chance to own an entire Jamul mountaintop. The property is not available for purchase separately and is intended to complement the adjoining residence. From its elevated setting, the land showcases truly breathtaking, uninterrupted views—stretching across San Diego County to the west and, on clear days, capturing sweeping vistas of the Pacific Ocean from Mexico to Catalina Island. To the east, the landscape opens to timeless Old West scenery, creating a striking contrast of natural beauty in every direction. A recently completed boundary line adjustment, finalized by Walsh Engineering in coordination with the neighboring parcel (APN 597-101-02-00 – which measures 11.17 gross acres), enhances the usability of the land. Survey and related documents are available through the MLS. The parcel also benefits from access to a detached four-car garage conveniently located off Isla Vista Road. With its commanding elevation, privacy, and endless views, this land offers a unique opportunity to curate a legacy property in one of Jamul’s most scenic settings.
