Bathe in dew on Midsummer's Night in Iceland
Jónsmessa, or Midsummer's Night is celebrated on June 24th and is shrouded in a mysterious veil of folklore. However, the real midsummer's night is actually on June 21st, the longest day of the year when the sun never sets in Iceland.
Bathing in dew is referring to is a folkloric tradition in Iceland which says that it's healthy to bathe in the dewy grass on the eve of Jónsmessa. Icelandic folklore also states that on this night, cows gain the power of speech and seals become human. And if you sit on a crossroads where all four roads lead to separate churches at night, elves will attempt to seduce you with gifts and food.
Tonight the sun sets at 12:03 AM in Iceland and rises again at 02:56 which means that actually there is no real darkness, just a bit of twilight. Unfortunately though it's a rainy day so the chances of watching the midnight sun are slim.
Hiking on Midsummer's Night is very popular with Icelanders who like to spend the evening immersed in nature on top of a mountain.
