Guerrero is one of Mexico’s 31 states and is located on the southwest coast. It is best known for the tourist hubs of Acapulco and Zihuatanejo, which are about 200km from each other. Both cities are located on a bay, with great diving opportunities both inside and just outside of the bay.
Acapulco is a beach resort town and major port city. Less than 500m offshore near the mouth of Acapulco Bay is the island of La Roqueta, which is home to many popular dive sites.

Zihuatanejo used to be a small fishing village but has since developed into the third most-visited area of Mexico. The main attractions of this area are sportfishing, birdwatching, and scuba diving.

The protected bays of both cities are an ideal environment for beginner divers to go reef- and wreck diving. Farther offshore, there are deeper dive sites that allow more advanced divers to go wall-, drift-, and cave-diving. Both nearshore and offshore dive sites are accessible mostly by boat, and shore diving is limited. Local dive shops run daily trips to sites, ocean conditions-permitting. None of the dive sites are so far from shore that a liveaboard dive boat is necessary.
 

Acapulco and Zihuatanejo together offer a diverse array of fifty or so dive sites.

The majority of Zihuatanejo’s sites are suitable for beginners. “Caleta de Chon” and “Manzanillo” are shallow sites where the coral ecosystem is the main attraction. “La Piedra Solitaria” and “Los Morros de Potosi” are popular dive sites located farther offshore that are geared towards more advanced divers due to their deeper nature and stronger current.

Of the 20 dive sites in and around Acapulco Bay, the most popular sites are near offshore rock formations, such as “Las Cuevas” at La Roqueta Island and “Los Bajos de la Quebrada”, a site near the cliffs of La Quebrada. These sites are good for wall-diving and boast frequent sightings of whale sharks and humpback whales in the wintertime.
