Barra de Potosí Mexico Mangrove Lagoon Tours and Whales

Why visit Barra de Potosí

The village is tiny. At the 2011 census it had fewer than 400 residents, with three main streets crossed by two more, and it sits at the edge of Laguna Potosí. That scale is the appeal: you walk from the beach to the lagoon in minutes and eat within sight of the boats that caught your lunch.

The lagoon and its surrounding ecosystem cover about 800 hectares, including roughly 454 hectares of mangrove. Researchers have recorded more than 200 bird species here, along with butterflies, fish, reptiles and mammals. Most visitors come on day trips from Zihuatanejo or from inland communities, so weekdays feel especially quiet.

The best places to visit around the lagoon and beach

Laguna Potosí

The lagoon is the heart of the village and the reason most people come. Local boat operators run lagoon tours through the mangrove channels, and a trip usually takes a couple of hours. Go early or late in the day when the light is soft and the birds are active.

Playa Blanca

Barra de Potosí marks the southern end of Playa Blanca, a wide stretch of Pacific sand that feels empty outside weekends. Allow an hour or two for a long walk and bring shade, since the beach is open and exposed. Treat the surf with caution and ask locals where it is safe to swim.

The offshore rock formations

The beach is known for unusual rock formations, often called haystacks, standing just offshore. They are best photographed from the sand at low sun, and they give the shoreline its distinct profile. Walk along the water line rather than climbing on wet rocks.

The enramadas

Enramadas are open air restaurants covered in palm fronds, and they line both the lagoon edge and the beachfront. They fill up on weekends with families from nearby towns, so arrive before the midday rush or visit on a weekday. Order the fish of the day and ask what came in that morning.

Kayaking the channels

Villagers rent kayaks for paddling around the lagoon, which is a quieter way to see the mangroves than a motorboat. Plan on one to two hours and keep to the calmer water near the shore. Ask the owner about wind and tide before you set out.

Birds, whales and the open sea

Birdwatching in the mangroves

Of the 212 bird species identified in the area, 82 are aquatic or marine, and 23 are endemic. Bring binoculars and sit still at the water edge at dawn. A local guide on a lagoon tour will point out species you would miss alone.

Whale watching season

During the winter months villagers also offer humpback whale watching tours from the coast. Sea conditions decide whether boats go out, so keep your plans flexible. Choose an operator who keeps a respectful distance from the animals.

Stops along the nearby coast

Petatlán and the Santuario del Padre Jesús

Petatlán, the seat of the municipality that includes Barra de Potosí, lies on the Costa Grande between Zihuatanejo and Acapulco. Its large white sanctuary houses a 17th-century image of Christ that is a regional pilgrimage destination, especially in Holy Week. Allow an hour, dress modestly and check before you go whether services are under way.

Playa La Ropa

Playa La Ropa curves along the sheltered Bahía Zihuatanejo, whose calm water suits swimming. The name means beach of the clothes, after a shipwreck said to have carried Chinese silk. It makes an easy half day if you are staying in Zihuatanejo.

Playa Las Gatas

Boats leave from the pier in Zihuatanejo for Playa Las Gatas across the bay. The beach has white sand, palapas and snorkeling beside an artificial reef built in pre-Columbian times. The name refers to small, harmless sharks nicknamed she-cats for their whiskers.

Vicente Guerrero National Park

Created in 2023 between Ixtapa and Zihuatanejo, this park protects 724 hectares of dry jungle, mangrove swamp and coastal plain. It supports hundreds of bird species and reptiles, including crocodiles in the swamps. Keep a respectful distance from any wildlife and follow park signs.

Food and local flavors

Seafood is the point here, and the enramadas serve fish that arrived that morning. Look for pescado a la talla, a whole fish brushed with chile paste and grilled, and for ceviche made with lime and fresh catch. On the wider coast, pozole verde is a regional favorite, a hominy stew colored and flavored by ground pumpkin seeds and green chiles, served especially on Thursdays. In Zihuatanejo, the municipal market and the small family kitchens near it are good places to try regional cooking at the weekend. Ask before you order what is fresh, and let the cook guide you.

Where to stay

Barra de Potosí itself is the choice for travelers who want mornings on the lagoon and quiet evenings. Lodging in the village is limited and simple, so check current options and book ahead for weekends and holidays. Zihuatanejo suits most visitors: it keeps a relaxed, traditional town feel, with a pier, a market and many restaurants, and you can reach the lagoon on a day trip. Playa La Ropa is a good base if you want a beachfront stay on a sheltered bay and are happy to travel for your lagoon day. Ixtapa, a planned resort a few kilometers away, offers a larger range of hotels and a livelier evening scene, and it suits families and travelers who prefer resort comforts.

Best time to visit

The winter months are the most rewarding, because humpback whale tours run then and the lagoon is pleasant for long boat rides. Summer and early autumn bring heat, humidity and rain on this tropical Pacific coast, and the Pacific storm season runs through autumn, so check forecasts before you travel. Weekends fill with day-trippers from inland towns and from Zihuatanejo, so the village is calmest on weekdays. Holy Week brings large crowds and a famous Passion Play to nearby Petatlán, which is worth seeing if you plan ahead.

Getting there and getting around

Most travelers arrive at Ixtapa-Zihuatanejo International Airport, which has nonstop flights from Mexico City and seasonal service from some cities in the United States and Canada. Acapulco International Airport is the other major airport in the state. The Pacific Coast Highway, Highway 200, links Zihuatanejo, Acapulco and the towns in between, and intercity buses run along it. Barra de Potosí is known for day trips from Zihuatanejo, so ask your hotel about tours, drivers or the best connection to the village. Once there, the village is compact and easy to walk, and local operators run the lagoon boats and kayaks. If you drive, stay on main roads and travel in daylight.

A suggested itinerary

First day

Travel to Barra de Potosí in the morning and take a lagoon tour while the light is soft. Eat lunch at an enramada, then walk Playa Blanca and photograph the offshore rocks before sunset.

Second day

Return to Zihuatanejo and take a boat to Playa Las Gatas for snorkeling. Spend the late afternoon at Playa La Ropa and have pozole or fresh fish for dinner in town.

Third day

Visit the sanctuary in Petatlán or the national park near Ixtapa. In winter, swap one of these for a whale watching tour.
