Puerto Vallarta is a Mexican beach resort city located on the Pacific Ocean coast in the state of Jalisco. It is the second-largest urban agglomeration in the state after the Guadalajara Metropolitan Area. Puerto Vallarta's calm, warm-water bays are suitable for diving, and the city is famous for its sand sculptures. However, what may be most significant for residents of Siófok is the connection that the city has to their hometown. Yvonne, the daughter of the famous operetta artist Kálmán Imre and a native of Siófok, resides in this Mexican city.

Tourism in Puerto Vallarta has steadily grown over the years and accounts for 50% of the city's economic activity. The high season for international tourism in Puerto Vallarta runs from late November to March. Puerto Vallarta was a thriving Mexican village long before it became an international tourist destination. Tourism is a significant economic activity due to the climate, landscape, tropical beaches, and rich cultural history of the region.

Puerto Vallarta is also known as a walkable city. Its cobblestone streets and charming architecture make it a joy to explore on foot, and visitors can feel safe walking around day or night.
