Puerto Vallarta (often referred to as Vallarta or just PV) is known for its friendly atmosphere, so it’s not surprising that it attracts a lot of tourists. Many of the expats you’ll meet here started out as tourists. The ones I spoke to told me they came here on vacation but realized pretty soon that they didn’t want to leave. As soon as they went home, they changed their lives to move here. You can’t get a better stamp of approval than that.
