The Algarve’s beaches are a major destination, but for many the best of the country’s 1,700km coastline lies beyond this tourist hotspot – from sandy coves below the lush Sintra hills north of Lisbon to the expansive, clean sands of Nazaré – one of Portugal’s top surf towns.

Tell us about your favourite place to spread your towel, whether it’s a sheltered cove, a remote slice of sand accessible only on foot or somewhere to soak up the sun from a beach bar.

If you have a relevant photo, do send it in – but it’s your words that will be judged for the competition.

The best tip of the week, chosen by Tom Hall of Lonely Planet, will win a £200 voucher to stay at a Sawday’s property – the company has more than 3,000 in the UK and Europe. The best tips will appear on the Guardian Travel website, and maybe in the paper, too.
