Discover Rincon de Guayabitos, Riviera Nayarit, Mexico Rincon de Guayabitos Wrapped around the gentle Bay of Jaltemba, the charming beach resort Rincon de Guayabitos is a little-known gem on Mexico's Pacific Coast. Situated halfway between Puerto Vallarta and Tepic, Guayabitos sits amid jungle-covered hillsides and a lush agricultural valley. The town itself consists of little more than a 1 1/2-mile stretch of golden sand and two parallel streets.
