Barrio Guayabo Aguada

The entire team of wellness specialists at Ann Wigmore’s eponymous Natural Health Institute in Puerto Rico is well-trained in her revolutionary approach, which lauds the use of wheatgrass and “living foods” (strictly organic, raw, plant-based, and nutrient-rich foods) for nourishing and ultimately healing the body. While the accommodations are comfortably minimal, the beachside grounds make for an idyllic setting for the one-week intensive and two-week immersive programs—all of which are supplemented by customizable treatment plans of colonics, lymphatic massages, and more. You’re likely to feel an instant transformation but the institute’s goal is long-term education, effectively preparing graduates of the program to maintain the lifestyle back at home.
