Isla Espíritu Santo is an island in the Gulf of California, off the Mexican state of Baja California Sur. It is separated from Isla Partida by a narrow canal.
The Gulf of California is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately 4,000 km (2,500 mi). Rivers which flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui. The gulf's surface area is about 160,000 km2 (62,000 sq mi). Depths range from fording at the estuary near Yuma, Arizona, to in excess of 3,000 meters (9,800 ft) in the deepest parts.
Baja California Sur, officially the Estado Libre y Soberano de Baja California Sur, is the second-smallest Mexican state by population and the 31st admitted state of the 31 states which, with Mexico City, make up the 32 Federal Entities of Mexico.
Isla Partida is separated from Isla Espíritu Santo by a shallow, narrow channel. These two islands, in the Gulf of California, are protected by UNESCO as biospheres. They are located a short boat ride from La Paz, which lies on the Baja California Peninsula in Mexico. It has a land area of 15.495 km (9.628 mi) and is part of the Municipality of La Paz in Baja California Sur.
It has a land area of 80.763 square kilometres (31.183 sq mi), the 12th-largest island in Mexico. Isla Partida's land area is 15.495 square kilometres (5.983 sq mi). They are part of La Paz Municipality and are both a short boat trip from La Paz on the Baja California Peninsula.
La Paz is a municipality of the Mexican state of Baja California Sur. Its area of 20,275 km² makes it the municipality in Mexico with the fourth-largest area. It had a population of 290,286 inhabitants in the 2015 census. Its municipal seat, also named La Paz, is the state capital.
The Baja California Peninsula is a peninsula in Northwestern Mexico. It separates the Pacific Ocean from the Gulf of California. The peninsula extends 1,247 km from Mexicali, Baja California in the north to Cabo San Lucas, Baja California Sur in the south. It ranges from 40 km at its narrowest to 320 km at its widest point and has approximately 3,000 km of coastline and approximately 65 islands. The total area of the Baja California Peninsula is 143,390 km2 (55,360 sq mi).
There was human presence of the island already about 9,000 years ago.
The area is protected as part of the Área de Protección de Flora y Fauna - Islas del Golfo de California (APFF-IGC),and is an important eco-tourism destination. It was declared part of a Biosphere Reserve by UNESCO in 1995. Espíritu Santo is the only known habitat of the black jackrabbit. The islands are both uninhabited. Ensenada Grande beach, on Isla Partida, was voted the most beautiful beach in Mexico by The Travel Magazine and one of the top 12 beaches in the world. Sea kayaking is a popular activity around the island.
The UNESCO World Network of Biosphere Reserves (WNBR) covers internationally designated protected areas, each known as biosphere reserves, that are meant to demonstrate a balanced relationship between people and nature.

It is the successor of the League of Nations' International Committee on Intellectual Cooperation.
The black jackrabbit is a species of mammal in the family Leporidae. Endemic to Mexico, its only known location is Espiritu Santo Island in the Gulf of California. The IUCN has listed this species as "near threatened" because of its restricted range. This taxon is regarded by some authorities as being a subspecies of the black-tailed jackrabbit, found on the mainland of Mexico.
The surrounding reefs are home to parrotfish, angelfish,trumpetfish, Moorish idols, and rainbow wrasse, while many other species pass nearby including sharks, rays, turtles, dolphins, and even whales. Birds include brown pelicans, great blue herons, snowy egrets, turkey vultures, and hummingbirds. A large sea lion colony resides on Los Islotes, off the north tip of the islands; snorkeling with the females and young is a highlight of many tours.
Parrotfishes are a group of marine species found in relatively shallow tropical and subtropical oceans around the world. With about 95 species, this group displays its largest species richness in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion.
Holacanthus clarionensis, also known as the clarion angelfish, is a species of marine angelfish of the family Pomacanthidae found predominantly off the Pacific coast of Mexico, living in depths from 3 to 30 meters deep. This fish is popular in aquarium trade due to its colors and high price tag. This species can grow up to 20 cm in length. It is considered vulnerable, due to its distribution being restricted, and has climate change and severe weather that may affect it in the future, along with its resources being harvested.
The trumpetfishes are three species of highly specialized, tubular-elongated marine fishes in the genus Aulostomus, of the monogeneric family Aulostomidae. The trumpetfishes are members of the order Syngnathiformes, together with the seahorses and the similarly built, closely related cornetfishes.
Conservation-minded eco-adventurers were not the only ones attracted to the island, and by the 1990s the pressure on Isla Espiritu Santo was intense: a real estate developer wanted to create a resort casino on the island. Luckily Tim Means, founder of Baja Expeditions, who since 1974 had been a leading conservationist based in La Paz, formed a coalition of activists who were able to purchase part of the island from the ejido that was selling it to the casino resort developer. One-third of the funds came from Mexican funders, another third from American funders via the Nature Conservancy, and the rest through an anonymous gift to the World Wildlife Fund. Their subsequent donation of Isla Espiritu Santo to the nation is commemorated by a famous sculpture of a dove on the boardwalk in La Paz.
Early Holocene pearl oyster circular fishhooks, dating to 8750–8500 cal BP, have been discovered on Espíritu Santo Island. They've been found in Covacha Babisuri rock shelter on the island. This is one of the earliest known examples of shell fishhooks in the world.
The Holocene is the current geological epoch. It began approximately 11,650 cal years before present, after the last glacial period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch.
"The pearl oyster fishhooks and some of the associated tools from Espíritu Santo Island, in the southern Gulf of California in Mexico, are similar to those found in Australia, along the Arabian Sea (Roth 1904, Allen 1996, Beech 2003, Méry et al. 2008), and in Valdivia (Meggers et al. 1965:147)."
Similar fishhooks have also been reported from Cedros Island, also in Baja California.
La Paz is the capital city of the Mexican state of Baja California Sur and an important regional commercial center.

Harumi Fujita is a Japanese researcher of Mexican archaeology, who has specialized in pre-classical period of the northern states of Baja California and Baja California Sur. Her research has shown that fishing cultures had arisen in the area at the end of the Pleistocene period, indicating an occupation from at least 11,000 years ago. In a cave shelf known as the Babisuri Shelter, radiocarbon dating indicated the area may have been occupied 40,000 years ago.
