On his Independent Travel Podcast, travel expert Simon Calder revealed he's launched a "personal campaign" to encourage more Brits to discover the coastal gem of Cascais.

Located west of Lisbon along the "Portuguese Riviera", Cascais boasts "an intriguing combination of sun-worn houses, cafés, shops and smart hotels".

Perfectly compact for exploring on foot, with mild temperatures hovering around 15C throughout winter, Cascais offers an ideal refuge from Britain's chilly weather.

• New £20 Ryanair route to gorgeous city with 23C December weather and 300 days of sunshine

This fishing village and harbour first evolved into a seaside getaway during the 19th century and has welcomed visitors ever since.

Hailed as "one of Portugal's top beach destinations" by Lonely Planet, it draws crowds during summer months, though there's plenty to experience during quieter periods as well.

The historic centre spans just 2km - easily explored within an hour on foot - and is predominantly pedestrianised.

For those seeking green spaces, Parque Marechal Carmona sits at the heart of town with its expansive lawns, tranquil ponds and spots for outdoor picnics.

Throughout December, the park transforms into a festive wonderland featuring Christmas markets, dazzling light displays and seasonal entertainment, reports the Express.

Additionally, culture enthusiasts can explore Cascais' Museum Quarter, home to 13 museums and galleries.

There's also the opportunity to wander the 3km coastal promenade, where numerous cafes and eateries provide welcome rest stops along the way.

In December, the renowned Ferris wheel will grace Cascais Bay, accompanied by other festive attractions.

Catch a flight to Lisbon from your nearest airport and then hop on the "Linha de Cascais" urban railway, which leaves from Cais do Sodré train station in Lisbon.

Alternatively, you can arrange for a taxi from Lisbon to Cascais, which should set you back around €25 to €35.
