Baja California Sur

A long, dry, wildly beautiful peninsula, with two seas, desert mountains, and some of the emptiest coastline in North America.

State population: ~800,000

Capital: La Paz | Statehood: 1974

Baja California Sur (BCS) occupies the southern half of the Baja peninsula, stretching from the 28th parallel down to the tip at Cabo San Lucas. Its 2020 census population was about 798,000, spread across roughly 74,000 km² (about 28,500 sq mi), which makes it one of the least densely populated states in Mexico. It has five municipalities: Mulegé, Comondú, Loreto, La Paz, and Los Cabos. Most residents live in the south, in La Paz and Los Cabos, while the north is vast, quiet, and sparsely settled.

History

Long before European contact, the peninsula was home to the Pericú, Guaycura, and Cochimí peoples, whose rock art still survives in the mountains. The Sierra de San Francisco cave paintings are a UNESCO World Heritage Site.

The Jesuits founded Misión Nuestra Señora de Loreto in 1697, the first permanent mission in the Californias, and Loreto served as the colonial capital of the region for decades. Later centuries brought pearl diving, silver mining, and, in the late 1800s, a French-run copper operation at Santa Rosalía, which left behind the town's distinctive prefabricated iron architecture.

BCS stayed remote for a long time. The Transpeninsular Highway (Mex 1) wasn't completed until 1973, and BCS was admitted as a Mexican state in 1974, making it one of the country's youngest. Since then, tourism has become the backbone of the state's economy, alongside fishing, agriculture, and mining.

Geography & Climate

BCS has two very different coastlines. The Pacific side is cooler and windswept, with big surf, barrier-island lagoons, and long empty beaches. The Sea of Cortez side is calmer and warmer, with sheltered bays, island chains, and famously clear water. Between them runs a spine of desert mountains, with cardón cactus forests, palm-lined oases, and, in the Sierra de la Laguna, pine-oak forest at altitude.

The climate is arid to semi-arid, with sun nearly year-round and very little rain outside the late-summer storm season.

Winter: Nov – Feb | Mild, dry, and comfortable, with warm days and cool nights; peak whale season

Spring: Mar – May | Warm, dry, calm seas; arguably the best all-around window

Summer: Jun – Sep | Hot and humid, especially on the Sea of Cortez side; water is at its warmest

Fall: Oct – Nov | Cooling down; hurricane risk fades by November and conditions become very pleasant

Hurricane season runs roughly June through November, peaking August through October. Storms are less frequent than the season's reputation suggests, but always check forecasts when planning travel or boat charters in this window.

Getting There & Around

By Air

Los Cabos International Airport (SJD) is the main gateway, with the widest range of international and domestic flights. La Paz (LAP) and Loreto (LTO) also have airports with more limited service, mostly to major Mexican cities and a few seasonal US routes.

By Road

Mexico Highway 1 runs the length of the peninsula, and the drive between the major destinations is scenic and straightforward. La Paz to Los Cabos takes about two to two-and-a-half hours, and Loreto is roughly five hours north of La Paz. Distances are long and services can be sparse, so fill your tank when you can and avoid driving at night, when livestock and wildlife are on the road.

By Sea

Ferries connect La Paz (Pichilingue) to Mazatlán and Topolobampo on the mainland. Many visitors also arrive by yacht: BCS has marinas at La Paz, Los Cabos, and Loreto, among others, and is a favorite cruising ground for sailors.

Time zone

BCS observes Mountain Standard Time year-round (UTC−7), with no daylight saving changes.

Regions at a Glance

Los Cabos

The state's resort capital, at the southern tip. Two towns, Cabo San Lucas and San José del Cabo, are joined by a coastal corridor of beaches, golf, and luxury hotels, with world-class sportfishing and nightlife. (See our Los Cabos overview for more.)

La Paz

The state capital and the region's quieter, more local counterpart to Los Cabos. It has a long waterfront Malecón and easy access to Isla Espíritu Santo, Balandra Beach, and whale shark encounters.

The East Cape

A stretch of coastline between La Paz and Los Cabos, including Los Barriles, La Ventana, and El Sargento, known for wind and kitesurfing. Cabo Pulmo National Park, home to one of the oldest coral reefs in North America, is also here.

Todos Santos & the Pacific Coast

A Pueblo Mágico with a thriving art scene, colonial architecture, and surf beaches, about an hour from both La Paz and Cabo San Lucas.

Loreto & Bahía Concepción

A small, historic town with a Jesuit mission, a national marine park, and some of the best kayaking and fishing in the Sea of Cortez. Farther north, Bahía Concepción has quiet coves and some of Baja's most striking beaches.

The North: Mulegé, Santa Rosalía & Guerrero Negro

Oasis towns, historic missions, and wide-open desert. On the Pacific side, the lagoons of Ojo de Liebre and San Ignacio host gray whales, which come to breed and calve each winter.

Wildlife & Nature

The Sea of Cortez has been called "the world's aquarium," and the Islands and Protected Areas of the Gulf of California are a UNESCO World Heritage Site. Marine life includes blue, fin, and humpback whales, whale sharks, manta and mobula rays, sea lions, dolphins, and sea turtles.

Whale watching

Humpbacks and other whales move through the state's waters from roughly December through March, and gray whales visit the Pacific lagoons in the same window. Operators are regulated, and watching is boat-based only; swimming with whales is prohibited.

Whale sharks

La Paz Bay hosts whale sharks from roughly November through May. Choose licensed operators that follow no-touch and group-size rules.

Diving & snorkeling

Cabo Pulmo, Espíritu Santo, and the reefs around Loreto are among the best in the region. Visibility is generally best in late summer and fall.

Culture & Events

BCS is a blend of ranching, fishing, and mission-era traditions, layered with a newer, international community of artists, surfers, and retirees. Highlights include the Carnaval de La Paz in the spring, the Festival de La Paz in February, and various local fiestas tied to patron saints, especially in the smaller mission towns. Fresh seafood, fish tacos, and locally grown produce are staples, and the food scene has grown quickly in recent years, especially around Todos Santos and Los Cabos.

Practical Information

Money

The Mexican peso (MXN) is the local currency. US dollars are widely accepted in Los Cabos but less so elsewhere, and usually at unfavorable rates. Cards are common in tourist areas, but carry cash in smaller towns.

Language

Spanish is the primary language. English is widely spoken in Los Cabos and in tourism-oriented businesses, but far less so in the north and in smaller towns.

Safety & health

• BCS is generally considered one of the safer regions of Mexico for visitors, though normal precautions apply, especially in busy tourist areas and at night.

• Tap water is not safe to drink; stick to bottled or purified water.

• Sun and heat are the most common hazards. Use reef-safe sunscreen, a hat, and plenty of water.

• Many Pacific beaches have strong currents and rip tides. Check local conditions and swim only where it's clearly safe.

• Services are sparse outside the main towns, so plan fuel, water, and cash accordingly.

Entry requirements

Most Western visitors need only a valid passport and a tourist (FMM) permit, issued on arrival. Requirements vary by nationality, so check current rules with a Mexican consulate or official source before traveling.

Note: verify hours, fees, and entry requirements before travel, as these can change frequently.
