Tatvan is my ancestors native country, strange town beside the van lake.
Don't forget to visit nemrut, the second biggest crater lake in the world.
Actually three lakes (one salty, one regular and one hot lake) on the mountain top.
You may also visit Ahlat there, you may see the ancient stone cemetary from the Selcuk Empire and ancient stone houses built from ahlat stone.
Also buryan is the traditional meat dish. You may like it if you taste it.
