Lake Thingvallavatn is the largest „natural” lake of the country with an area of 83,7 km². Its greatest depth is 114 m and it reaches 13 m below sea level. The greatest length of the lake is 14,5 km and width 9,5 km. Sog, its discharge, is a 19 km long salmon river Olfusa, which tributes to the country’s largest glacial river. The average flow of the Sog river is 108 m³/sec. The lake’s catchment area is 90% underground and the water from the thousands of cold springs has a constant temperature of 3-4°C the whole year round. The anglers, who use boats for their fishing, have to be careful and watch out for changes in the weather. The lake becomes a boiling pot, when the wind starts blowing.
The catch in the lake has always been a necessary part for the survival of the farming families on the lake.

Best fishing time
The brown trout is most visible during the evening. The char is no respecter of seasons or times of day. Please keep in mind that brown trouts bigger than 5 pounds are not recommended for consuming because of high volume of mercury (*hg) (quicksilver) so we recommed catch and release for the big brown trout.
We like to stress the importance of keeping the place tidy. So littering in the area is strictly forbidden. Cars and other vehicles must stay on designated roads. Please leave your card on the window shield inside the car visible for the national park guards.
