Parking at Loma Alta Park is very limited and can become difficult. However, Sunny Ridge Rd, which runs parallel to Lincoln and perpendicular to Loma Alta Drive just North of the equestrian area, has lotsa parking on both sides of the street. And there is a large parking lot off of it. Please do not park in the small parking lot off Palm near the bathroom; it is reserved for AC100 staff and is marked.
