Wildlife Watching in San Luis Obispo County

See land and sea creatures great and small

Removed from Likes

From flittering monarch butterflies as light as a feather to elephant seals that tip the scales at more than 5,000 pounds/2,268 kilograms, San Luis Obispo County has an incredible variety of wildlife—and ways to see it. For starters, head to the rugged strip of coastline known as Piedras Blancas (Spanish for “white rocks”), alongside Highway One roughly 7 miles north of San Simeon. Here, some 17,000 elephant seals, once hunted to near extinction, haul up on the rocky sands to breed, have their young, molt, and rest. From observation areas above the sands, watch bellowing bull elephant seals as large as mini-vans battle for territory, while quieter, smaller females nurture their plump, cigar-shape pups. Knowledgeable docents are usually on site.

From late October into February, visit the remarkable monarch butterfly groves at Pismo State Beach to see these orange-and-black beauties as they congregate in great numbers during the winter. Recently, the population has averaged around 25,000 butterflies but more than 100,000 monarchs have gathered during peak seasons.

At Morro Bay, listen for the banging sound of sea otters using little rocks as tools to open shellfish. Scan the skies and waters for herons and egrets (there’s a lively rookery along the shoreline, near the natural history museum at Morro Bay State Park), as well as a huge number of migratory waterfowl and peregrine falcons (a pair often nests on Morro Rock). Join a guided kayak trip to paddle across the bay with a knowledgeable guide to see diving cormorants and basking harbour seals as well as sea otters, and to learn about local oyster farming. Paddle across the bay to climb tall sand dunes, a great place to look for migrating blue, gray, and humpback whales.
