Interesting facts

  • Close offshore the San Lucas submarine canyon plunges more than 600 metres, bringing deep ocean water almost to the foot of the arch.
  • The canyon's underwater sandfalls, rivers of sand pouring down its slopes, were first seen by a Scripps expedition in 1959 and later filmed by Jacques Cousteau.
  • The rocky ridge around the arch reaches about 61 metres above the sea, several times the height of the opening itself.
  • The granite belongs to the Peninsular Ranges batholith, a long belt of Cretaceous intrusions that forms the backbone of Baja California.
  • The protected area around the arch covers nearly 4,000 hectares and is part of the Gulf of California islands World Heritage Site, inscribed in 2005.
  • Pelican Rock, just inside the bay, is the most popular snorkelling spot near the arch, with sea lions often swimming among the fish.
  • The Gulf of California that begins at the arch is home to around 900 species of fish.

Why it is worth it

At the very tip of the Baja California peninsula the land runs out in a ragged spine of granite, and at its end the sea has punched a hole straight through the rock. El Arco — also simply called Land's End — stands where the Pacific Ocean meets the Gulf of California, and on a clear day the difference between the two is visible from the water: calm, turquoise water on the gulf side, heavy Pacific swell on the other. The arch itself rises roughly three storeys above the waterline, a squat, massive gateway rather than a delicate span, and the pinnacles around it climb much higher.

The rock is far older than the resort that now photographs it. The granite of this headland crystallised deep underground in the Cretaceous, around 115 million years ago, and was later exposed and cut into fins, needles and caves by waves, wind and tide. The contrast between the two seas on either flank of the ridge is part of what shaped it: one side sheltered, the other constantly pounded, so erosion works unevenly and leaves the harder rock standing as walls and bridges.

Around the arch the headland gathers several of Los Cabos' best-known sights into a few hundred metres. On the sheltered side lies Playa del Amor, Lover's Beach, a small cove of pale sand between the cliffs; over the narrow neck of land, on the Pacific side, is the rougher Divorce Beach, where the surf makes swimming dangerous. Flat rocks near the arch are a haul-out for a colony of California sea lions, and the waters here belong to a marine protected area established in 1973; seasonally, migrating whales pass offshore. The bay's glass-bottom boats circle the rocks so passengers can look down into the clear water as well as up at the stone.

Much of El Arco's fame comes from its setting at the very end of a long peninsula, and it has become the emblem of Cabo San Lucas, repeated on the advertising of every hotel along the Los Cabos corridor. Seen from a boat in the low evening light, with the granite warming in colour against the sea, it earns its reputation.

Getting there

The arch stands about 2.5 km from the centre of Cabo San Lucas, at the mouth of its harbour; Cabo San Lucas International Airport (CSW) is about 9 km away. The formation is reached by boat: water taxis, glass-bottom boats and cruises leave from the Cabo San Lucas marina and from Médano Beach, and many drop passengers at Lover's Beach. Landing directly at the arch is difficult, as the water level around the rocks rises and falls sharply.

From the encyclopaedia

The arch of Cabo San Lucas is a distinctive granitic rock formation at the southern tip of Cabo San Lucas, which is itself the extreme southern end of Mexico's Baja California Peninsula. The arch is locally known as "El Arco," which means "the arch" in Spanish, or "Land's End." It is here that the Pacific Ocean becomes the Gulf of California.
