Puerto Vallarta was once named as La Ciudad Mas Amigable en el Mundo (The Friendliest City in the World), as the sign reads when entering from Nayarit. Today, the presence of numerous sidewalk touts selling time-shares and tequila render the city's atmosphere more akin to tourist-heavy resorts like Cancun and Acapulco, but overall the city's reputation remains relatively undiminished.
Tourism makes up roughly 50% of all economic activity in Puerto Vallarta. The high season for international tourism in Puerto Vallarta extends from late November through March (or later depending on the timing of the College Spring Break period in the USA.) The city is especially popular with US residents from the West Coast because of the number of convenient flights between Puerto Vallarta and Los Angeles, San Francisco and Seattle. The air routes between Puerto Vallarta and Los Angeles and Puerto Vallarta and San Francisco are by far the most heavily traveled of all air routes to the city.
Puerto Vallarta is also a popular destination for domestic tourists. It is a popular weekend destination for residents of Guadalajara (tapatíos), and a popular national destination for vacations such as Semana Santa (the week preceding Easter) and Christmas. Also in recent years Acapulco has experienced a rise in drug related violence and consequently Puerto Vallarta has absorbed a lot of the Mexico City resort vacation business (Acapulco has long been a common destination for tourists from Mexico City).
Puerto Vallarta has become a popular retirement destination for US and Canadian retirees. This trend has spawned a condominium development boom in the city.
Rapid growth in tourist volume in Puerto Vallarta has given rise to rapid growth in hotel and rental apartment construction. This growth has spilled over from the city limits into Nuevo Vallarta in the neighboring state of Nayarit. The area is one of the fastest growing regions in the Americas.
