About this Location

Facility Overview

Parking Lot #1 is an expansive open-air surface parking and staging facility situated on the secure grounds of the Diablo Canyon Power Plant (DCPP), operated by Pacific Gas and Electric Company (PG&E) along Diablo Canyon Road on California's central coast. Positioned on the elevated marine terrace overlooking the Pacific Ocean, this lot is configured to serve badged utility personnel, outage contractors, industrial transport vehicles, and authorized visitors traveling to the energy complex. Designed with wide circulation lanes and an open layout without any overhead height restrictions, Parking Lot #1 comfortably accommodates standard passenger cars, light trucks, high-roof utility vans, and large heavy-duty commercial transport vehicles.

Prime Location & Nearby Attractions

Located on the rugged, preserved coastline of San Luis Obispo County just north of Port San Luis and Avila Beach, Parking Lot #1 is strategically positioned within the Diablo Canyon energy installation. While situated in a highly regulated industrial and coastal conservation zone, key nearby geographical and recreational landmarks include:

Diablo Canyon Power Plant & Administration Complex: Immediate on-site access to administrative buildings, maintenance shops, and security command facilities.
Pecho Coast Trail & Point San Luis Lighthouse: Located a short drive south down Diablo Canyon Road toward the Port San Luis security checkpoint; docent-led coastal hiking trails offer sweeping panoramas of San Luis Obispo Bay and the historic 1890 lighthouse.
Avila Beach & Harford Pier: Approximately 7 miles south via the access corridor, offering coastal dining, waterfront strolls, seafood markets, and beach recreation.
Montaña de Oro State Park & Point Buchon Trail: Adjoining the northern boundary of the 12,000-acre Diablo Canyon lands, known for rugged ocean cliffs, sea caves, and secluded coastal trailheads.

Access, Navigation & Transit Connectivity

Vehicle ingress to Parking Lot #1 is governed by Diablo Canyon Road, a private, secure coastal roadway extending northwest from Avila Beach Drive past Port San Luis. Because the property is part of a federally regulated critical infrastructure facility, access past the entry security gate is strictly limited to credentialed plant personnel, badge-carrying contractors, and security-cleared visitors with advance authorization. The corridor connects seamlessly back to Avila Beach Drive, which links east to U.S. Highway 101, providing high-speed highway connectivity to San Luis Obispo, Pismo Beach, and the greater Central Coast. Public transit does not operate inside the plant security perimeter, making private vehicle arrival, utility fleet transportation, or company-arranged shuttles the primary modes of access.

Visitor & Driver Tips

Public entry is restricted; do not navigate past the outer security checkpoints at Port San Luis without valid credentials, pre-authorization, and government-issued photo identification. Drivers visiting the area for recreational coastal trails (such as the Pecho Coast Trail) must book through PG&E’s docent-led hiking programs and park in designated visitor assembly areas at Port San Luis rather than proceeding down Diablo Canyon Road. Authorized motorists should observe strict on-site speed limits, watch for wildlife crossing the coastal roadway, and arrive early during major refueling outages when shift traffic along Avila Beach Drive can create local delays.
