The Sea of Cortez
Cousteau called it the world's aquarium. Red desert islands, glass-calm coves, whale sharks feeding off the city waterfront — and anchorage after anchorage entirely your own.
The Sea of Cortez is what happens when the Sonoran Desert falls into a sea so rich Jacques Cousteau pronounced it the world's aquarium. North of La Paz, a chain of UNESCO-listed islands — Espíritu Santo first among them — unfolds as cove after rust-red cove where a sixty-metre yacht anchors utterly alone. Whale sharks feed within sight of the city's waterfront from late autumn; sea lions keep their own islet; blue whales winter off Loreto. It is the closest thing charter has to a safari, and it sits a short flight from the American West Coast.
“We swam with a whale shark before breakfast and didn't see another boat until La Paz.”
The gallery
Signature anchorages
The world's aquarium: whale sharks feeding off the La Paz waterfront, a 600-strong sea lion colony at Los Islotes, and UNESCO-listed desert islands with barely another mast in sight.
- BalandraLa Paz's protected bay — a shallow scoop of pale turquoise capped at under a thousand visitors a day, guarded by El Hongo, the mushroom rock that is the city's emblem; anchor off and paddle in.
- Ensenada Grande, Isla PartidaThree lobes of turquoise under rust-red volcanic cliffs, routinely ranked among the world's most beautiful anchorages; take the middle lobe and stay the night.
- Caleta PartidaThe flooded gap between Espíritu Santo and Isla Partida and the archipelago's best all-round shelter; at high tide the tender slips through the cut to the seaward side.
- Isla San Francisco'The Hook' — a white crescent with textbook holding in sand, a ridge walk with the whole southern sea below, and a salt flat behind the beach.
- San EvaristoA fishing hamlet under the Sierra de la Giganta where the panga fleet still sets out at dawn; a well-sheltered bay and a glimpse of the sea's working life.
- Agua VerdeA remote green-water cove walled in by the Giganta's rock faces, reached by sea or a long dirt track — as far from a beach club as this coast gets.
- Puerto EscondidoThe 'hidden port' — a near-landlocked natural harbour below Loreto with a modern marina taking 200-footers; gateway to the blue whales of Bahía de Loreto.
The scene
Bisbee's Black & Blue
Cabo's marlin week and the richest event in sport fishing — purses have topped US$11.5 million. The 2026 edition runs 19–24 October, with fishing days 21–23.
Baja Ha-Ha
The great American cruisers' rally, San Diego to Cabo San Lucas each autumn; the 2026 fleet departs 2 November and takes about ten days over it.
Carnaval La Paz
One of Mexico's oldest carnivals, celebrated since 1888 — six days of parades, floats and free concerts take over the malecón; the 2026 edition ran 12–17 February.
The whale months
Blue whales calve in Bahía de Loreto from late January into March; grey whales and their calves fill Magdalena Bay on the Pacific side, an overland day trip away.
Steinbeck's log, Cousteau's aquarium
John Steinbeck spent six weeks collecting specimens here with Ed Ricketts in 1940 — The Log from the Sea of Cortez is still the shelf's best companion — and Jacques Cousteau later called the gulf 'the world's aquarium'.
Table & stay ashore
Flora's Field Kitchen, San José del Cabo
Dinner inside a 25-acre organic farm in the Sierra de la Laguna foothills; everything is grown or reared moments from the table, the meat from the farm's own 150-acre ranch.
Acre, San José del Cabo
A farm estate in the palms behind town; the kitchen marries global instincts with whatever the land gives that week.
SEARED, One&Only Palmilla
Jean-Georges Vongerichten's steakhouse at the peninsula's original luxury resort — fifteen cuts of Wagyu with the Sea of Cortez beyond the terrace.
Las Ventanas al Paraíso
Rosewood's resort on the Corridor between the two Cabos — the standing address ashore when the boat lies at Land's End.
Baja Club, La Paz
A 1910 colonial villa on the malecón, remade by Grupo Habita with 32 rooms, a central patio and a rooftop bar over the bay; the Michelin Guide lists it, and the whale sharks feed in the bay beyond.
A week, sketched
La Paz — board at CostaBaja
Board at Marina CostaBaja, walk the malecón at dusk, and — mid-November to mid-April — swim with the whale sharks feeding in the bay before dinner.
Balandra
A slow morning on the sandbars of the city's protected bay, El Hongo standing on the point, then north across the channel to the islands.
Espíritu Santo & Los Islotes
Snorkel the 600-strong sea lion colony at Los Islotes — open to swimmers September to May — then drop back to Ensenada Grande for the night.
Isla San Francisco
The Hook: a ridge walk before breakfast, paddleboards over glass, and a long lunch on the crescent.
San Evaristo & the Giganta coast
Coffee with the panga fleet at San Evaristo, then a run north beneath the rock walls of the Sierra de la Giganta to Agua Verde.
Agua Verde to Puerto Escondido
Green-water snorkelling in the morning; by evening the yacht lies inside Puerto Escondido's near-landlocked harbour below Loreto.
Bahía de Loreto
Blue whales in late winter, the empty island beaches of the national park otherwise; disembark at Marina Puerto Escondido, a short drive from Loreto's airport.
