Alto Mar

The Villa encompasses approximately 10 acres, anchored by an 8,000-square-foot Tuscan-inspired residence with two additional guest residences and separate staff accommodations. Expansive lawns and mature landscaping surround a resort-style pool and spa, outdoor living spaces, sports field, half basketball court and imaginative play and recreation areas. Beyond the developed grounds, open acreage offers possibilities for equestrian facilities, gardens and orchards, agriculture, livestock and more.
The Ranch spans approximately 13.45 acres, pairing a remodeled 3,100-square-foot main residence with additional residences and apartment-style accommodations. A two-story equestrian and entertaining barn, stables, arena, extensive storage, and dedicated covered and uncovered Airstream/RV parking with utility hookups complement the open acreage, sweeping views and potential for additional home sites.
Together, Alto Mar is a rare 23-acre legacy compound in Coastal North County—two complete estates, offered as one remarkable whole or individually, each entirely its own.
