About Trinidad

Trinidad is a seaside city in Humboldt County, located on the Pacific Ocean 8 miles (13 km) north of the Arcata-Eureka Airport and 15 miles (24 km) north of the college town of Arcata. Situated at an elevation of 174 feet (53 m) above its own North Coast harbor, Trinidad is one of California's smallest incorporated cities by population (367 residents in 2010, up from 311 residents in 2000). Trinidad is noted for its spectacular coastline with ten public beaches and offshore rocks, part of the California Coastal National Monument, of which Trinidad is a Gateway City. Fishing operations related to Trinidad Harbor are vital to both local tourism and commercial fishery interests in the region.

Before 1700 AD, Yurok people established the village of Tsurai on bluffs overlooking Trinidad Bay. The first European sighting of Trinidad Harbor was by the Portuguese navigator Sebastian Rodriguez Cermeño, who did not make landfall. The next visit was by Bruno de Heceta and Juan Francisco de la Bodega y Quadra of the Spanish Navy. Their two ships anchored in Trinidad Bay on 9 June 1775. On 11 June, which was Trinity Sunday, a formal act of possession was conducted. The area was named "la Santisima Trinidad".

Settlers arrived on the James R. Whitting in 1850 and founded the town, renamed Warnersville in honor of R.V. Warner, one of the settlers. The first post office opened in Trinidad in 1851.

Trinidad was the original county seat of Klamath County, one of California's original counties, from 1851 to 1854. At that time Trinidad became part of the newly created Humboldt County after its creation in 1853, with its county seat in Eureka. Klamath County was finally dissolved in 1874.

During the American Civil War from July to October 1863, California Volunteers fighting the local Indians in the Bald Hills War were stationed in the town, in Trinidad Camp to protect it and the coast road from Indian raids, until they were moved four miles north to Camp Gilmore. Trinidad was incorporated in 1870 as a City of the State of California, USA.
