Iceland is a land home to many incredibly diverse natural sites. From geysers to waterfalls, every feature presents dramatic beauty that so many people crave to see.

When planning a visit to Iceland, it can be difficult to squeeze everything into a tight itinerary. Two amazing glacier lagoons are Fjallsárlón and Jökulsárlón, but which one should you pick? Join us as we uncover the wonders of both to inspire your trip. It’s time for the ultimate glacier lagoon showdown!

What is a Glacier Lagoon?

Glacier lagoons are lakes that emerge at the foot of glaciers. As ice caps retreat, they carve out hollows in the Earth's surface, filling them with meltwater. Approximately 10,000 years ago, at the end of the ice age, Iceland witnessed the birth of the first of many glacier lagoons.

Glacier lagoons feature a mesmerizing combination of elements. They often have a pristine, icy blue hue, owing to the fine sediment called "glacial flour" that reflects and scatters light in the water. The lagoons are surrounded by towering glacier-carved cliffs, showcasing dramatic, rugged landscapes.

Floating within the lagoons you will find majestic icebergs, varying in size and shape. These icebergs break off from the glacier's edge and float in the calm waters of the lake. They are known to change in appearance over time, with the size, shape and arrangement of icebergs constantly evolving. Regardless of when you visit, the lagoons will always be different than before, creating a truly unique experience every time.

Fjallsárlón Glacier Lagoon

Fjallsárlón sits in southeastern Iceland, near the country's renowned Vatnajökull National Park. This lesser-known glacier lagoon is a hidden gem that offers a captivating experience for anyone that takes a visit.

Fjallsárlón is smaller in size compared to its more famous counterpart, Jökulsárlón. However, what it lacks in size it compensates with its serene atmosphere, with a magnificent display of icebergs floating on the tranquil waters.

Convenient Location - This is something that both lagoons have in common. Jökulsárlón’s is also situated right along the Ring Road, making it ideal if you’re planning to explore attractions right in the vicinity of Iceland's famous route. Directly opposite Jökulsárlón’s and just on the other side of the Ring Road, you will find Diamond Beach, meaning that no matter which lagoon you opt to visit, you won’t have to miss out on the stunning black sand and ice chunks of this beach.

Which Glacier Lagoon Should I Visit?

Choosing between Jökulsárlón and Fjallsárlón depends entirely on personal preferences. If you’re looking to experience something world-famous on a larger scale, Jökulsárlón is the ideal choice. It offers a mesmerizing display of icebergs, with excellent wildlife-watching experiences and activities to enjoy. If you’re looking for something more secluded and intimate, Fjallsárlón is definitely worth exploring. It offers a serene ambiance with far smaller crowds, allowing you to appreciate Iceland’s beauty without all the tourists.

Ultimately, both have their unique charm. Visiting both lagoons, if time permits, can provide you with a well-rounded experience of Iceland’s glacial landscapes.
