Lake Thingvallavatn is the largest lake in Iceland, just over 32 square miles and located only 40 minutes from Reykjavík. The lake drains into the Atlantic Ocean in southwest Iceland via the Sog and after the bigger Ölfusá river. On its northern shore stands Thingvellir, the historical meeting place of the Althingi (parliament) from 930 until 1798. The lake lies along the North Atlantic Ridge, sitting where the North American and Eurasian tectonic plates separate from each other. It is also the home of the ice age brown trout that grows to enormous proportions.

The giant brown trout of Thingvallavatn have evolved in isolation since the last ice age. These Legendary fish are on the bucket list of most anglers and this is the place you go to set your own personal record for Brown trout. These trout average right around 8 pounds and these extraordinary fish can grow to a weight of over 30 lbs., and specimens in excess of 20 lbs. are frequently caught in peak fishing times. In Thingvallavatn, you never know what the next cast will bring, but chances are it will be big.
