Coahuila de Zaragoza is Mexico's third-largest state, a vast stretch of northern desert and mountain along the Rio Grande border with Texas. It blends colonial wine country in Parras de la Fuente, the turquoise pools and unique desert ecosystem of Cuatro Ciénegas, the cool pine forests of Arteaga, and the industrial and cultural cities of Saltillo and Torreón.

Beaches by vibe
Pick by the mood you want — quiet, social, family, or active — and we point you at where that style lives along the coast.
Family Friendly
Family Friendly
Río Mezquites and Presa Venustiano Carranza, with their gentler access and designated swimming areas, suit families best; Poza Azul's boardwalk-only setup works well for those who prefer viewing over swimming
Adventure
Adventure
The combination of the Bilbao and Dunas de Yeso sand landscapes with the nearby pozas delivers the most varied single-day adventure mix in the state
Quiet And Local
Quiet And Local
Parque Nacional Los Novillos and Presa Venustiano Carranza see mostly local and regional visitors rather than international tourism, offering a more low-key experience
Scenic
Scenic
The turquoise-against-desert contrast at the Cuatro Ciénegas pozas and the adjacent white Dunas de Yeso are the two most visually striking water-adjacent settings in the state
Things to do at the beach
Beyond swimming and sunbathing — the activities that make a coastal day in Coahuila memorable.
Practical beach info
What to know before you head to the coast — season, getting there, facilities, and what it costs.
What To Bring
Water shoes or sandals, sun protection, a towel, and plenty of drinking water are essential at every site, since facilities are minimal outside the entrance areas at Río Mezquites and Los Novillos
Safety
None of these locations have lifeguards in the conventional sense, though Don Martín has a volunteer safety association (El Faro de Don Martín) overseeing its main access points; swimmers elsewhere should assess conditions themselves and follow posted rules at the Cuatro Ciénegas pozas closely
Best Visiting Hours
Morning to early afternoon is best at the desert pozas and Don Martín to avoid peak sun; Los Novillos' forested canyon stays cooler and can be visited comfortably later in the day
Combining Sites
Río Mezquites, Poza Azul, Las Playitas, and the Dunas de Yeso can all be combined into a single day within the Cuatro Ciénegas Valley, while Don Martín and Los Novillos each stand alone as longer trips given their distance from the state's main cities
What to bring
A short packing list for a comfortable beach day — adjust for season and the specific spot.
- Sun protectionHigh-SPF sunscreen, hat, polarised sunglasses, light long-sleeve cover-up.
- HydrationReusable bottle, salty snacks for longer days, electrolyte sachets if it’s hot.
- FootwearWater shoes for pebble or rocky entry, flip-flops for sand, dry pair for the trip home.
- Swim & coverQuick-dry towel or sand-resistant mat, change of swimwear, light cover-up for restaurants.
- Cash & valuablesSmall notes for beach clubs and rentals; waterproof pouch for phone, keys, cards.
- ExtrasReef-safe sunscreen near protected coastline, a book, a small first-aid kit for jellyfish or scrapes.
Beach safety
Hard-earned guidance — read this before you swim, especially if you’re unfamiliar with the coast.
Critical
Swim where lifeguards are posted and follow flag warnings — green is safe, yellow is caution, red means no swimming. Rip currents are the leading beach hazard worldwide.
Caution
Watch for tide changes and marine life — jellyfish blooms, sea urchins on rocky entries, occasional shark or stingray advisories. Don’t swim alone, especially at dawn or dusk.
Tip
Reapply sunscreen every 90 minutes and after every swim. Take shade between 11 am and 3 pm — the sun is harsher than people expect, even when the air is cool.
Practical
Keep valuables out of sight or back at the accommodation. Beach theft is a small-but-real risk at busy beaches; never leave bags unattended while you’re in the water.
