When Soph and I first moved across to Spain, this is where we first lived, the Costa Calida. We drove down to Puerto de Mazarrón, in the January and stayed at a hotel there, while viewing. The beaches were glorious, clean and empty.
We viewed the property we’d come to see, which was 20 minutes or so inland, and fell in love with the place.
At the time, the airport back then was San Javier, the military base that allowed commercial flights.
The Costa Cálida: Spain’s Underrated Coastal Gem
If you’re craving Mediterranean vibes without the crowds of the Costa del Sol or the overbuilt flashiness of the Costa Blanca, Costa Cálida might just be your perfect escape. Translating to the “Warm Coast”, this slice of south-eastern Spain stretches along the region of Murcia, boasting a staggering 250 kilometres of varied coastline, sun-soaked beaches, charming towns, and a slower, more authentic pace of life.
Whether you’re a sun-seeker, culture lover, foodie, or someone just looking to take a proper breather, this underrated corner of Spain has something to offer. Here’s your no-nonsense, straight-talking guide to Costa Cálida.
Where Is Costa Cálida?
Costa Cálida runs from El Mojón on the border with Alicante, down past the famous La Manga strip and on to Aguilas in the south. It’s all part of the Murcia region, which doesn’t get quite the same attention as its neighbours—but that’s part of the appeal.
This is a coast that’s warm most of the year, with over 300 days of sunshine annually. Summers are hot, winters are mild, and the sea is a comfortable temperature for much of the year.
Top Spots to Explore Along Costa Cálida
1. Cartagena
A port city with layers upon layers of history. Roman ruins, an impressive amphitheatre, and modernist architecture all jostle for attention here. It’s also got a vibrant marina and plenty of tapas joints where you can enjoy fresh seafood while watching the world go by. The Batería de Castillitos are worth a visit if you are a bit of a history buff. Going from Puerto de Mazarrón through to Cartagena on the scenic coastal road is the easiest way to get here.
2. Murcia City
Okay, it’s not on the coast, but it’s only about 30-40 minutes inland and well worth the detour. The cathedral is a stunning mishmash of Gothic and Baroque, the plazas are lively, and the food scene leans heavily into hearty Murcian fare that sticks with you (in a good way). Check out the Real Casino de Murcia, if you like elegance. They do however have a dress code to visit here, so no rocking up in vest and flip flops.
It is a requirement that all visitors be smartly dressed at all times.
The dress code for gentlemen is well groomed. Equally suitable smart attire is required for ladies. From time to time, the Real Casino de Murcia may organise functions requiring a specific dress code. This dress code will be advised in advance.
Tracksuits, running shoes, hiking style boots, beach type sandals, flip-flop and athletic footwear are not permitted. Sportswear is also not permitted.
While you’re there, marvel at the English Library. There are 25 study areas and a collection of 20,000 books dating back to the 17th century.
3. La Manga del Mar Menor
This unique strip of land separates the Mediterranean Sea from the Mar Menor, Europe’s largest saltwater lagoon. It’s a bit of a love-it-or-hate-it kind of place—lots of high rises and resorts—but the calm, shallow waters make it ideal for families and water sports.
4. Mazarrón
A favourite with expats and Spanish holidaymakers alike, Mazarrón offers a quieter take on coastal living. The beaches around Bolnuevo and Puerto de Mazarrón are golden, clean, and not too crowded even in summer. Great for those who like a bit of peace with their sangria. Also the Bolnuevo Erosions are a popular tourist viewing area, a real natural beauty.
5. Aguilas
Right down at the southern tip, Aguilas is a proper Spanish seaside town. There’s a castle on the hill, colourful festivals (especially Carnaval),, the Infanta Doña Elena auditorium building and some seriously photogenic coves. You can hike, snorkel, or just relax with a beer by the shore.
Beaches Worth Finding Your Flip-Flops For
- Playa de Calblanque – A protected nature reserve with wild, undeveloped beaches. No bars, no shops, just sand dunes, clear water, and peace.
- Playa de la Higuerica (Aguilas) – Quiet, scenic, and very Spanish.
- Playa de Bolnuevo – Iconic red rock formations nearby and a wide beach popular with families.
- Playa del Castellar (Mazarrón) – Flat, spacious and great for swimming.
- Mar Menor Beaches – Calm and shallow, perfect for paddleboarding or floating about without a care in the world.
Transport and Getting Around
1. Flying In
Murcia International Airport (RMU), near Corvera, is the main gateway to Costa Cálida. It’s small but efficient, with seasonal flights from the UK and other parts of Europe. Alicante Airport is also just a bit further north and offers more regular flight options.
2. Hiring a Car
If you want to make the most of your trip, a car is highly recommended. Public transport is patchy, and while there are buses and a few train routes, they don’t reach all the charming nooks and crannies. Roads are generally quiet and easy to navigate, and parking is usually hassle-free outside of city centres.
3. Public Transport
If you’re staying put in one town, local buses are fine for getting around. There’s a train line connecting Murcia and Cartagena, and some coastal routes are served by intercity buses. But really, if you’re up for a bit of exploring, four wheels will get you further, faster.
When to Visit Costa Cálida
- Spring (March–May): Ideal. Warm but not too hot. Everything’s in bloom, and the beaches are quiet.
- Summer (June–August): Hot. Very hot. Great if you love sunbathing but be ready for the heat. Best to stick close to the water.
- Autumn (September–November): Still warm, sea temperatures perfect, and fewer crowds.
- Winter (December–February): Mild and sunny, though not exactly beach weather. Good for hiking, city breaks, and enjoying a quieter side of Spain.
Things to Eat and Drink
You’re in for a treat. Costa Cálida does seafood spectacularly, and the inland farms keep the fruit and veg top-notch too.
- Caldero Murciano – A traditional rice dish made with fish and cooked in a cast iron pot.
- Zarangollo – Scrambled eggs with courgette and onion. Simple but brilliant.
- Tapas – Naturally. Try the local meats, cheeses, and fresh grilled prawns.
- Local wines – Jumilla and Yecla (slightly inland) are two wine regions producing reds that punch well above their weight.
Final Thoughts: Why Costa Cálida Deserves a Spot on Your Radar
Costa Cálida offers all the beauty and sunshine you expect from a Spanish coastal break, minus the relentless crowds and overpriced beach clubs. It’s authentic, relaxed, and still just under the radar enough to feel like you’ve discovered something special.
Whether you’re after a slow beach holiday, cultural days out, great food, or simply somewhere new to explore, Costa Cálida quietly delivers. So, hire that car, pack the sun cream, and start plotting your route—this warm coast is waiting.
You’ll often here ex-pats living here, refer to the micro-climate and yes we did notice how great the weather is. We quite often used to pop up to Cartagena for a day out, and used to combine this with a visit to the huge Eroski supermarket, who at the time did the cheapest fuel in the area,
