May is a great time to visit Iceland! The days are long, the weather is improving, and
North Iceland becomes more accessible thanks to the reduced chance of snow. As summer approaches in Iceland, more outdoor tours open up to visitors.
During May, you can enjoy
snorkeling in Silfra,
whale and puffin watching,
ice caving in the Langjokull glacier, and more. May is also a wonderful time to visit the numerous hot springs around Iceland, as the warmer weather makes it more pleasant than it can be in the snow. May is the beginning of the summer season but is still before the peak, so visitors have access to more outdoor tours, but attractions are less busy than they are at the height of summer in June and July.
