Sleepy Cat Farm is open for viewing only twice a year though the Garden Conservancy Program. These 13 acres in Greenwich have evolved over 25 years into a garden wonderland, featuring both manicured and wild vistas, including a path along a woodland stream bordered by an oak and beech forest, Japanese garden, koi pond, fountains, terraces, arbors, boxwood topiary, and more.

Register on the Garden Conservancy website. Cost, $10.
