The QuirosteOhlone people were the first known to inhabit the Año Nuevo area. After Mission Santa Cruz was founded in 1791, the Quiroste population plunged due to the various diseases that the Spanish had brought with them. The Spanish maritime explorer Sebastian Vizcaino sailed by the point on January 3, 1603. His diarist and chaplain of the expedition, Father Antonio de la Ascensión, named it Punta de Año Nuevo for the day on which they sighted it in 1603. They had recently stopped in Monterey and had passed Año Nuevo while heading north. The first European land exploration of Alta California was the Spanish Portolà expedition of 1760-70. Guided by Vizcaino's landmarks as it traveled north along the coast in 1769, the explorers recognized Point Año Nuevo. On the return journey to San Diego, the party camped at Año Nuevo Creek on November 19. Franciscan missionary Juan Crespi noted in his diary, "We...halted on a steep rock, in sight of the point which we judged to be Año Nuevo, on the bank of an arroyo which empties into the sea." After the mid-19th century, developments occurred, including the development of Año Nuevo Island and agriculture in the surrounding region. Once home to a large population of elephant seals, hunters greatly reduced the seal population by overhunting the species. Since the mid-20th century, the seal population has had a rebound and multiplied greatly. Elephant seals can be seen today on the wildlife reserve. Save the Redwoods League purchased a parcel known as Cascade Creek in 2020 that links Año Nuevo with Big Basin Redwoods State Park.
Pinniped colonies
s, California sea lions, sea otters, and other marine mammals come ashore to rest, mate, and give birth in the sand dunes or on the beaches and offshore islands. Hundreds of thousands of people come to witness it each year. Año Nuevo State Park is the site of one of the largest mainland breeding colonies for the northern elephant seal. The seals attracted so much interest that early reservations are needed during the winter breeding season. The males battle for mates on the beaches and the females give birth to their pups on the dunes. From mid-December through late March, daily access to the reserve is available on guided walks only. Most of the adult seals are gone by mid-March, leaving behind the weaned pups who remain through April. The elephant seals return to Año Nuevo's beaches during the spring and summer months to molt and can be observed during this time through a permit system. Reservations for a guided walk during the breeding season are available by phone.
