More ways to explore the area's outdoor wonders
The morning air over Loreto Bay tastes like salt and warm stone as the boat eases away from the marina and the island’s dark cone appears on the horizon. Waves push and pull around the hull; dolphins often punctuate the crossing with quick arcs, daring you to watch. On approach, volcanic cliffs rise raw from turquoise water, birds wheel on thermals and sea lions call from offshore rocks.
