Let’s not get into the whole mundane debate as to whether water is actually “blue”, and instead simply celebrate the visual, and ostensibly blue feast that so many of the world’s waters give us.

Yep, we’ve strived to find no fewer than 30 places across the globe where you will find water at its gloriously bluest. Sit back, relax and have a tall drink as we guide you through them.

Phi Phi Islands, Thailand

It's fair to say that the Phi Phi Islands have been late bloomers among popular holiday isles - as late as the early 1990s, you would have needed to be a pretty adventurous traveller to contemplate coming here.

So much has changed, with visitors to Phuket and Krabi alike making it a priority to check these islands out, especially on account of their marvellously clear waters.

Valley of the Five Lakes, Poland

For waters that really are nigh-on as clear as glass, it’s difficult to look beyond these breathtaking five alpine lakes nestled way up in the High Tatras mountain range, along the border of Poland and Slovakia.

The biggest of those lakes is known as Morskie Oko, or “Eye of the Sea”. It’s been named one of the most beautiful lakes on the planet by The Wall Street Journal, and that’s quite the honour.
