Introduction
Lake Nemrut is the jewel of one of the largest volcanic craters on earth — a deep blue lake cradled inside the vast caldera of Mount Nemrut, the great volcano that rises beside Tatvan at the south-western corner of Lake Van. Within the ring of the collapsed volcano lie crater lakes, meadows, and woods, hidden high above the shores of the larger lake. A natural wonder of the Kurdish highlands, Lake Nemrut is a world apart, sheltered within the rim of a sleeping volcano.
(This Nemrut, a volcano on Lake Van in Bitlis, is a different place from the famous Mount Nemrut of Adıyaman with its giant statues.) This profile looks at the caldera, its lakes, and its setting.
Key Takeaways
• Lake Nemrut is a crater lake inside the caldera of the Nemrut volcano, beside Lake Van.
• The Nemrut caldera is one of the largest volcanic craters in the world.
• It lies near Tatvan in Bitlis Province, at the south-west corner of Lake Van.
• The caldera holds a large cold lake and a smaller warm lake, with meadows and woods.
• It is a different Nemrut from the statue-topped Mount Nemrut of Adıyaman.

Where Is Lake Nemrut?
Lake Nemrut lies within the crater of the Nemrut volcano, just west of the town of Tatvan in Bitlis Province, at the south-western tip of Lake Van. The volcano rises above the lakeshore not far from the city of Bitlis, and across the water stands the great cone of Mount Süphan, its sister volcano. A winding road climbs from Tatvan up to the rim, from where the hidden world inside the crater is revealed.
A Giant Caldera
Mount Nemrut is a volcano whose summit long ago collapsed inward after great eruptions, leaving an enormous bowl-shaped crater — a caldera — several kilometres across, ringed by steep walls. It is counted among the largest calderas in the world. Standing on the rim and looking down into this vast hollow, with its lakes and greenery far below, is one of the most astonishing sights in the region, a hidden landscape sunk within the mountain itself.
Lakes Within the Crater
The floor of the caldera holds water. A large, deep, cold lake fills much of the crater — the lake that gives the place its fame — its blue surface mirroring the surrounding walls. Nearby lies a smaller lake whose waters are warmed by the volcanic heat still stirring below, so that the two lie side by side, one cool and one warm. Around them spread meadows, birch woods, and hot springs, making the crater floor a green and living world enclosed by the ring of the mountain.
The Volcano and Lake Van
Nemrut’s story is bound up with that of Lake Van itself. In ancient times the volcano’s lava flows are thought to have helped block the outlet of the basin, trapping the waters that became the great lake. The volcano is not extinct but dormant, its warm springs and heated lake hinting at the fire that still sleeps beneath. Together with Mount Süphan across the water, Nemrut is one of the great volcanoes that shaped this whole corner of the Kurdish highlands.
Lake Nemrut Today
Today the Nemrut caldera and its lakes are a protected natural wonder and a growing destination for visitors, who drive up to the rim to gaze into the crater and descend to picnic by the water and bathe in the warm springs. Set high above Lake Van, this hidden world within the volcano remains one of the most extraordinary landscapes in the Kurdish highlands — a lake inside a mountain, sheltered from the world outside.
Timeline
ancient eruptions — The Nemrut volcano erupts and its summit collapses into a caldera.
prehistory — Lava flows help dam the basin, forming Lake Van.
over time — Lakes, meadows, and woods fill the floor of the great crater.
modern era — The caldera becomes a protected natural area and destination.
today — Lake Nemrut is a celebrated natural wonder above Tatvan.
Frequently Asked Questions
Where is Lake Nemrut?
Lake Nemrut is inside the crater of the Nemrut volcano near Tatvan, in Bitlis Province, at the south-western corner of Lake Van in eastern Turkey.
What is the Nemrut caldera?
It is the enormous collapsed crater of the Nemrut volcano, one of the largest calderas in the world, holding crater lakes, meadows, and hot springs.
Is this the same as Mount Nemrut with the statues?
No. This Nemrut is a volcano beside Lake Van in Bitlis; the famous Mount Nemrut with the giant stone heads is a different mountain in Adıyaman Province.
Why are there two lakes in the crater?
One large lake is cold, while a smaller nearby lake is warmed by the volcanic heat still present beneath the caldera, so the two lie side by side.
