Dia is nationwide chain of Spanish supermarkets (similar to Tesco, Asda .etc).
Located on the Carretera Carboneras just a 5 minute walk from the Parque Commercial, Dia Mojácar is open from Monday to Saturday, 9:00 AM to 9:30 PM and can cater to all of your shopping needs.
Dia offers a good range of products that cover everything from fresh fruit and veg, to dairy, meat, drinks and bread plus everything else you'd expect to find in a large supermarket. It's worth noting that this particular Dia doesn't feature a fresh meat or fish counter, but has plenty of pre-packaged options.
They're also well-stocked with household necessities, bathroom essentials and cleaning products.
It's a good choice for convenient, quality shopping that a lot of locals use, it's a lot less busy than Mercadona in the summer too, which can come in handy.
