The three-hour-plus evening drive back may stretch the boundaries of a single-day trip, but a boring drive up and down the 5 is a small price to pay for this illuminated hillside walkthrough from artist Bruce Munro. The ticketed installation includes the 15-acre Field of Light, a flowery blanket of 58,800 fiber-optic spheres; Light Towers, 69 towers of glowing wine bottles; Gone Fishing, 30 circular cluster of 25 colorful fishing rods; and Fireflues, a pathway with 9,720 flickering lights.
4380 Hwy 46 E, Paso Robles. Thu–Sun evenings; $43.
