The Southeast is dominated by Vatnajökull, Europe’s largest glacier by volume. This is where you’ll find the world-famous blue ice caves (October–April), the best glacier hiking, and the jaw-dropping Jökulsárlón glacier lagoon
Blue ice caves are seasonal — October to March/April only.
Book ice cave tours months in advance, especially for winter.
Allow at least one full day here — ideally stay overnight in Höfn.
Glacier hiking is available year-round from Skaftafell.
