Overview
Piedras Negras sits on the Rio Grande in the Mexican state of Coahuila, directly across the border from Eagle Pass, Texas. It's a working border city rather than a resort town, popular with travellers visiting family, doing cross-border business, or exploring a slice of authentic northern Mexican life away from the tourist trail. It also happens to be the widely credited birthplace of the nacho, a fact that gives any visit a fun conversation-starter. For UK travellers, flights to Piedras Negras typically route via Mexico City before a short domestic hop north.
Best time to fly to Piedras Negras
Coahuila has a desert climate, so summers (June to August) are extremely hot, often exceeding 38°C, while winters are mild with cooler evenings. The most comfortable months to visit are October to November and March to April, when daytime temperatures are warm rather than scorching. Use the When to book chart above to see how fares shift across the year, since demand and pricing on this route can vary by season and connection availability.
Airlines and routes
There are no direct flights from the UK to Piedras Negras. The typical journey involves a long-haul flight from London to Mexico City with carriers such as British Airways, Aeromexico, Air France, KLM or Iberia (roughly 11–11.5 hours direct from London, longer with a European stopover), followed by a shorter domestic connection to Piedras Negras International Airport (PDS). Some travellers instead fly into a Texas gateway such as San Antonio or Houston and cross the border by land via the international bridges linking Piedras Negras with Eagle Pass, which can be a practical alternative depending on the fares shown in the charts above.

Travel essentials
UK passport holders don't need a visa for tourist stays in Mexico of up to 180 days, but you will need a valid passport and a completed tourist card (FMM), usually arranged online or on arrival. The currency is the Mexican Peso (MXN); pounds sterling aren't accepted locally, so carry pesos or a card for payments. No special vaccinations are mandatory for entry, though routine travel health precautions are sensible, and travel insurance is strongly recommended for any trip to Mexico.
