Learn to differentiate calls of the males, females, and pups as they gather en masse throughout the winter months.

Sea otters

Sea otters can be found all along the Central Coast of California, including around San Simeon and Hearst Memorial State Beach.

Tide pools

Tide pools are shallow pools of seawater found along the coast, and sea grasses, urchins, crabs, fish, and more thrive in them. Near Coast Discovery Center, tide pools are smaller than elsewhere along the coast due to the sandiness of the cove, but they provide a compact overview of the ecosystems around.

Plankton Under a Microscope

Another fascinating way to explore life found around Coastal Discovery Center is by examining plankton! These microscopic organisms are crucial components in the ecosystem even though they’re so tiny that they’re invisible to the naked eye. At Coast Discovery Center, guests can make slides of sea water droplets and explore the teeming life within under a microscope.

Rainbow Trout Watershed

Watersheds are also crucial to the health of a broad ecosystem because they provide the movement of fresh water from higher land down through to coastal areas, thereby providing both water and nutrient exchange along the way. Coastal Discovery Center helps visitors learn all about the local watershed that is important to fish, like rainbow trout, throughout the course of their life cycles.

The Delta Sub & Shipwrecks

Through the deeper sea exploration of the Delta Submarine, Coastal Discovery Center has intriguing information about farther-flung structures. Learn all about the extinct underwater Davidson volcano and over a thousand shipwrecks off California shores, including a vessel that was torpedoed by a Japanese submarine off the coast of nearby Cambria.
