The 50-acre flower fields of Carlsbad Ranch are ablaze in a sea of the carmine, saffron and snow-white blossoms of ranunculuses. Take the Palomar Airport Rd exit off of I-5, head east and turn left on Paseo del Norte. Outside of the official season, there are some rose gardens on the site which, depending on the condition of the blooms, may be accessed via the Armstrong Garden Center next door.
