Picture this: You're sitting beachside, toes in the soft sand, with the sun setting majestically, and an umbrella-topped cocktail in your hand. This comes after a day spent whale-watching, fishing, and lounging on the beach. Tomorrow? Maybe you'll go for some kayaking, a day trip to a nearby town, and a massage. Is this heaven on Earth? Indeed: Welcome to Los Cabos, on the southern tip of Mexico's Baja Peninsula. This is where the desert and the ocean collide. The crowds have discovered this gem, so it's not for those intent on getting away from it all. But you can still find solitude on many hidden beaches.
