Bathing in Iceland's Blue Lagoon has emerged the most popular bucket-list travel experience among millennials in a new survey.

After polling 5,000 young people around the world aged 18-35, youth travel outfit Contiki compiled “The No Regrets Travel List” which reveals the top 20 most coveted holiday experiences for 2017 among millennials.

At the top of the heap is the Blue Lagoon, a milky blue pool of mineral-enriched bathing waters with purported health and skin-healing properties, set against Iceland's dramatic backdrop.

The water is self-cleansing and renews itself every 40 hours.

It's not surprising to see Iceland at the top of the list, given the country's soaring popularity as a travel destination.

Thanks to aggressive and innovative tourism campaigns, Iceland has become top of mind among nature lovers and adrenaline junkies in recent years and expects to welcome two million tourists in 2017 -- five times the number it received in 2010. For perspective, the population of the country is 332,000.

Iceland's starring role in the wildly popular series "Game of Thrones” has also helped feed the mythology of the country's landscape, often described as the land of fire and ice.
