Iceland Lakes
186 mapped8 regionsGlacial lagoons includedFishing needs a permit
Iceland has thousands of lakes, but a handful stand out: Þingvallavatn (the largest natural lake, in the Þingvellir rift valley), Mývatn (the shallow, bird-rich lake in the north), and the glacial lagoons Jökulsárlón and Fjallsárlón on the South Coast, where icebergs drift from the retreating ice. Most named lakes are easy roadside stops; the highland reservoirs need an F-road and a 4×4.

ActivityWhen & how to visit Iceland's lakes
Þingvallavatn anchors the Golden Circle and pairs with the Þingvellir rift and the Silfra dive site. Mývatn in the north is a full day on its own — pseudocraters, lava fields and nearby geothermal areas. The South Coast glacial lagoons — Jökulsárlón, Fjallsárlón and Breiðárlón — sit near Vatnajökull and change year to year as the ice retreats. Highland lakes and reservoirs like Þórisvatn, Langisjór and Hágöngulón usually need an F-road and a 4×4, and most routes only open in summer. Fishing anywhere needs a permit bought per water body, and swimming rules vary by lake — check local signage first.

questions
What is the largest lake in Iceland?
Þingvallavatn is Iceland’s largest natural lake by surface area (~84 km²), in the rift valley at Þingvellir National Park, about 45 minutes east of Reykjavík. Þórisvatn, a highland reservoir, is larger still at high water levels but is regulated for hydropower.
Can I swim in Iceland’s lakes?
Some lakes allow swimming, but most are cold year-round and a few are protected or have unstable shorelines. Þingvallavatn is a well-known cold-water dive and snorkel site (Silfra) — only with a licensed operator and a drysuit. Always check local signage before entering the water.
Do I need a permit to fish in Iceland?
Yes. Angling in Icelandic lakes and rivers requires a permit, bought per water body from the landowner or local angling association, and you must disinfect gear used abroad before fishing. Rules vary by lake — check before you cast.
What are the glacial lagoons — are they lakes?
Jökulsárlón, Fjallsárlón and Breiðárlón are glacial lagoons: lakes that formed as glaciers retreated, filled with icebergs calving off the ice. They sit on the South Coast near Vatnajökull and are among Iceland’s most-visited water bodies.
Which lakes can I reach without a 4WD?
Þingvallavatn, Mývatn, Kleifarvatn and the South Coast glacial lagoons all have paved-road access suitable for any car. Highland lakes and reservoirs like Þórisvatn, Langisjór and Hágöngulón usually need an F-road and a 4×4, and most only open in summer.
Why is Mývatn famous?
Mývatn, in North Iceland near the Krafla volcanic system, is a shallow, biologically rich lake ringed by pseudocraters and lava formations. Its name means “midge lake” — the summer midges are harmless but dense, so many visitors bring a head net.
