Location
The Piedras Blancas Elephant Seal Rookery is located along California's iconic Highway 1 near the Piedras Blancas Light Station, just a few miles north of San Simeon and the turnoff for Hearst Castle. With its easy access and free parking, this site is one of the most accessible places in the world to observe elephant seals in their natural habitat. Multiple well-maintained boardwalks and viewing platforms ensure that visitors can enjoy the sights while respecting the seals' space.

History
The story of the Piedras Blancas Elephant Seal Rookery is one of both near-extinction and remarkable recovery. In the 19th century, elephant seals were hunted to the brink of extinction for their blubber, which was rendered into oil. By the early 20th century, fewer than 100 seals were believed to exist, all on a remote island off Baja California. Thanks to international protections, their population rebounded, and in the early 1990s, elephant seals began appearing at Piedras Blancas. Today, the rookery is home to an estimated 25,000 seals, making it one of the largest colonies on the West Coast.
But the area's history stretches even further back. The name “Piedras Blancas,” meaning “white rocks” in Spanish, refers to the white, guano-covered rocks offshore. Indigenous peoples, such as the Northern Chumash and Salinan Tribe, lived in harmony with this coastline for centuries, relying on its rich marine resources until Spanish settlements arrived in the late 1700s. Sadly, by 1810, the Native Americans that thrived here were all dispersed and no indigenous villages remained. The land was then later part of the Rancho de Piedra Blanca land grant in the mid 1800s. In 1869, there were two large shipwrecks off the coast here due to weather and the unforgiving terrain. Just a few years later in 1875, the nearby Piedras Blancas Light Station was built, serving as a beacon for mariners navigating the treacherous coastline.

Visiting Today
The rookery is open year-round and free to the public, with no reservations required. Visitors can stroll along wooden boardwalks and observation areas that hug the bluff tops, offering incredible views of the seals, and interpretive panels provide wonderful insights into their behavior. Volunteers from Friends of the Elephant Seal are often on hand to answer questions and share fascinating facts. Groups of seals are typically just a few feet away from the viewing areas, so binoculars aren’t needed to enjoy them. However, there is so much wildlife to see, I always have them on hand to view sea birds and migrating whales in the distance.
There are two main boardwalks, each heading out in opposite directions from the main parking lot. Visitors are also able to enjoy hiking along the 2-mile Boucher Trail just to the north, which also provides more opportunities to see elephant seals and other wildlife. Named after Jim Boucher, a former Piedras Blancas light station manager, the trail includes bluffs, grassland, and wetland areas, making it one of my favorite places to take in the magnificent coastal views.
Travelers along Hwy 1 will also enjoy several small parking areas and viewing areas along the coastline. The vista point about a mile south of the official Piedras Blancas Elephant Rookery is another great spot to see these seals and other wildlife safely from the bluff tops. There are also informative plaques here sharing this region’s history. There was recently a carcass of a large fin whale that washed up on the rocks at this spot. As of the writing of this post, skeletal remains can still be seen along one of the beaches.

Seasons
One of the most remarkable aspects of the Piedras Blancas Elephant Seal Rookery is that it offers something to see during every season:
Winter (December to February): This is pupping and breeding season, the most dramatic time to visit. Witness males battling for dominance and mothers giving birth and nurturing their newborn pups.
Spring (March to May): During this quieter season, molting occurs. Seals shed their outer layer of skin and fur in a process that’s both fascinating and essential for their health. Be prepared for a pungent aroma!
Summer (June to August): Juvenile seals and some adult females haul out to rest, offering a more relaxed viewing experience.
Fall (September to November): Subadult males practice sparring on the beach, preparing for their future roles in the colony’s social hierarchy.

Piedras Blancas Motel: Now closed, this old motel sits along the bluff tops a few miles north of the light station within Hearst San Simeon State Park. Some of the buildings are now providing private residences to state park staff, but short bluff top paths provide visitors an opportunity to explore and see even more elephant seals.
