About Puerto Vallarta

South of the Cuale river, Playa Los Muertos draws crowds to the Romantic Zone with its pier and beach bars; fifteen kilometres further south, Playa Mismaloya marks the cove where John Huston filmed Night of the Iguana. Pacific waters hold 28-30 °C82-86 °F from July to September, with Gustavo Díaz Ordaz airport fifteen minutes by Highway 200.
