Vatnajökull National Park: The Region Around the Lagoon
Jökulsárlón sits inside Vatnajökull National Park, under Europe's largest ice cap. A guide to the wider region — Skaftafell, Fjallsárlón, ice caves and Höfn.

Everything at Jökulsárlón flows, literally, from Vatnajökull — the largest ice cap in Iceland and, by volume, in Europe. It's a vast dome of ice covering a large share of the island's south-east, feeding dozens of outlet glaciers that grind down toward the lowlands in every direction. Breiðamerkurjökull, the tongue that calves into Jökulsárlón, is just one of them. Beneath the ice lie active volcanoes and some of Iceland's highest peaks, and the cap is thick enough in places to be measured in hundreds of metres. Standing at the lagoon, you're looking at the drainage of a single frozen giant that dominates this whole quarter of the country. Grasping that scale is the key to understanding the region.
One of Europe's largest national parks
Since 2008 the ice cap and a huge swathe of land around it have been protected as Vatnajökull National Park, which by common account covers around 14% of Iceland — among the largest national parks in Europe. In 2019 it was inscribed as a UNESCO World Heritage Site, recognised for the dramatic interplay of ice and fire: glaciers meeting volcanoes, outwash plains, and landscapes still being actively shaped. Jökulsárlón and Diamond Beach sit within its boundaries, which is part of why they remain free, open and relatively undeveloped rather than fenced attractions. The park is enormous and varied, with entrances and hubs scattered around its edges, so most visitors experience only one or two corners of it on any single trip.
Skaftafell: the park's southern hub
About 60 km west of the lagoon along the Ring Road, Skaftafell is the main visitor hub for the park's southern side and the usual launch point for guided activities on the ice. From its visitor centre, walking trails fan out toward Svartifoss — a waterfall framed by black basalt columns — and toward glacier viewpoints, while guided glacier hikes and, in winter, ice cave trips set off onto the nearby outlet glaciers. If Jökulsárlón is about watching ice from a distance, Skaftafell is where you go to get onto it. Many longer south-coast itineraries treat the two as a pair — Skaftafell for activity, the lagoon for spectacle — an easy hour's drive apart along the same road.
Fjallsárlón and the neighbouring lagoons
Jökulsárlón is the famous one, but it isn't the only glacial lagoon on this stretch. Fjallsárlón, a short way west along the Ring Road, is smaller and much quieter, and gets you closer to the glacier face itself — a genuinely good addition rather than a substitute for its bigger neighbour. Smaller meltwater lagoons dot the foot of the ice cap here and there along the road. The reason Jökulsárlón dominates is a combination of sheer size, the drama of its icebergs, the tidal channel and Diamond Beach directly across the road — a concentration of features the others can't match. But if you have time and want the ice without the crowds, the smaller lagoons are worth the short detour.
Glacier hikes and winter ice caves
The park is where Iceland's headline glacier activities happen. In summer, guided glacier hikes take you out onto the crevassed surface of the outlet tongues with crampons and a guide — never something to attempt alone. In winter, roughly mid-October to March, the same glaciers open up their most famous feature: natural ice caves, meltwater-carved chambers glowing blue inside the ice, accessible only with guides and only when conditions are judged safe. Both are conditions-dependent and seasonal, and both are separate undertakings from a lagoon visit, though many people combine a winter ice cave with a stop at Jökulsárlón since they're in the same area. Always go with licensed operators; the glaciers are beautiful and genuinely dangerous in equal measure.
Höfn and the eastern edge
East of the lagoon the Ring Road runs about 75 km to Höfn, a small fishing town that serves as the main service base for this corner of the country — fuel, food, beds and a reputation for langoustine. It makes a natural overnight stop for anyone not trying to drive the whole thing from Reykjavík in a day, and puts you within easy reach of the lagoon for early-morning or late-evening light, before the tour buses arrive. Beyond Höfn the Ring Road continues on into the fjords of the east. For a visitor weighing how to fit Jökulsárlón into a trip, Höfn is the answer to 'where do we sleep' — close enough to make the lagoon a relaxed morning rather than a marathon.
