Forget Rio: Lopes Mendes is two miles of unspoiled,deserted,powder-white sand that leads to some of the world's clearest ,most crystalline waters.There are no beach shacks or restaurants here;instead,you'll find thick,wild sea shrub,almond trees,and squat palms,perfect for napping beneath.It's quite a trek-a three-hour drive to Angra dos Reis from Rio,then a ferry,then a taxi-boat,then a short hike through a forest-but well worth the effort
