Jutting down from the northwest corner of Mexico, the bony finger of Baja California runs 760 miles south from the US border to the golden beaches and pounding surf of Cabo San Lucas. Although on average only 25 miles wide, Baja California is a remarkable haven of marine life. Above all, it offers some of the finest whale-watching in the continent especially for the endangered Pacific Grey Whales which come to breed each year in the tranquil waters of Magdalena Bay. Not to be outdone, the Sea of Cortez laps the eastern shores of the peninsula and is one of the richest bodies of water on the planet, dubbed the “aquarium of the world” by Jacques Cousteau himself. For natural enthusiasts, dedicated live-aboard cruises offer guests the chance to observe dolphins, whales (humpback, California Gray, killer and blue whale), manta rays, turtles and even whale sharks. For adventure seekers, you can snorkel amongst sea-lions, kayak around the UNESCO Biosphere Reserve of the island Espiritu Santo or surf the famous southern breaks. At the tip of the peninsula, luxurious beach resorts provide an ideal end to any itinerary and are surrounded by sleepy colonial towns.
