14. Explore an Ice Cave Beneath a Glacier in Iceland

For cruise travelers stopping in Reykjavik or Akureyri, Iceland, an excursion into an ice cave beneath Vatnajökull Glacier is a surreal and otherworldly experience. These shimmering blue tunnels are carved by glacial meltwater and change shape every season, meaning no two visits are exactly alike. Equipped with crampons and a guide, you’ll walk deep into the frozen underworld, where the ice glows in eerie shades of blue, white, and turquoise. Pro Tip: The best ice caves form in winter (November-March) when the ice is most stable. If you're visiting in summer, consider an ice tunnel tour instead.
