Ernest Hemingway named his cabin cruiser Pilar, and he spent enough time in the waters around Cayo Guillermo to set the climax of his final novel here. Islands in the Stream ends with a chase through these cays - low-lying, mangrove-fringed, the kind of place where shallow water turns impossible shades of green before dropping abruptly into the deep blue of the Atlantic. The beach that bears his boat's name, Playa Pilar, sits at the island's western tip, a crescent of white sand backed by dunes that reach nearly 15 meters high. It is consistently ranked among Cuba's finest beaches, and for once the superlative is earned. The sand is flour-fine, the water warm and transparent, and the nearest town is a causeway and a half away on the Cuban mainland.
Before the resorts, Cayo Guillermo belonged to fishermen and charcoal producers. They lived lightly on the island, harvesting mangrove wood for fuel and casting nets into waters that teemed with life. In the 1960s, deep-sea fishermen discovered the channel between the cay and the open Atlantic - prime territory for marlin, swordfish, and the kind of big-game fishing that drew Hemingway to Cuba in the first place. The island remained otherwise quiet for decades, a place known only to those who worked its waters or chased its fish. That changed in 1993, when the first resort went up - part of Cuba's post-Soviet pivot toward tourism as economic survival. The construction marked a turning point not just for the island but for Cuba's relationship with its own coastline.
Cayo Guillermo is not a place you stumble upon. Reaching it requires crossing a long causeway from the Cuban mainland to neighboring Cayo Coco, then a second, shorter causeway to Guillermo itself - a journey that feels like driving across the surface of the sea, with shallow turquoise water stretching to the horizon on both sides. The alternative is Jardines del Rey Airport, built to serve the archipelago's resort strip.
For years after the resorts opened, Cuban citizens could not visit their own island unless they worked there. Critics called the policy "tourist apartheid" - sun-drenched cays reserved for foreign currency while Cubans watched from the mainland. The restriction was lifted after 2000, and today Cubans with motor transport make the causeway crossing to enjoy Playa Pilar on weekends. Hotel staff commute daily from the mainland towns of Moron and Ciego de Avila, an hour or more each way, living in the gap between the Cuba tourists see and the Cuba that serves them.
The name of the archipelago - Jardines del Rey, Gardens of the King - dates to the colonial era, when Spanish explorers named these scattered cays for their sovereign. The chain stretches roughly 200 kilometers along Cuba's northern coast, a barrier reef system sheltering hundreds of tiny islands from the open Atlantic. Most remain uninhabited, their mangrove roots hosting juvenile fish, their shallow flats attracting flamingos and roseate spoonbills.
Cayo Guillermo sits in the western portion of this chain, between the Bay of Dogs to the south and the Atlantic to the north. The island is small - walkable in a morning - but its position gives it access to both the calm, warm waters of the bay and the deeper currents beyond the reef. Snorkelers find coral gardens within wading distance of shore. Divers head to the drop-offs where the shallow bank plunges into open ocean. And at dusk, the western beach catches the last light in a way that explains why ten hotels now crowd an island that once housed only fishermen's shacks.
From the air, the Jardines del Rey archipelago looks like a brushstroke of pale green against deep blue - a chain of islands so low they barely break the surface. Cayo Guillermo appears as a teardrop of vegetation surrounded by water that shifts from milky turquoise over the shallows to navy where the continental shelf falls away. The causeway connecting it to Cayo Coco traces a thin white line across the water, an improbable thread of road suspended between sea and sky.
The contrast between the island and the mainland is stark. To the south, Cuba's interior is green and hilly, dotted with towns and the sugar fields that once drove the economy. To the north, there is nothing but water until the Bahamas, a hundred miles away across the Old Bahama Channel. Cayo Guillermo sits precisely on that boundary - connected to Cuba by concrete and politics, facing the open Atlantic with nothing but sand and coral between itself and the horizon.
Located at 22.595N, 78.666W off Cuba's north-central coast in the Jardines del Rey archipelago. Jardines del Rey Airport (MUJR) serves the resort cays and sits on neighboring Cayo Coco, roughly 15 km east. From cruising altitude, the archipelago appears as a chain of low sandy islands strung along the edge of a shallow turquoise bank, with the deep blue Atlantic to the north. The causeways connecting the mainland to Cayo Coco and then to Cayo Guillermo are clearly visible as thin white lines across open water. Best viewed at 3,000-5,000 feet to appreciate the color contrast between the shallow bank and deep ocean. The Old Bahama Channel separates this coast from the Bahamas to the north.
