First u have to buy tickets.once u get in to the cave u'll feel the fresh air...then u have to use boat in the cave and ur trip will start... a really amazing place. u'll be amazed by the crystals u see .
U can find different resturants around the area. The food is ok and u'll enjoy the view of the place. there'd be chelo kabab and soup and drinks (non-alcoholic ). and also the price is cheap.
Favorite Dish: Like any restaurant in Iran u can have chelo kabab or Joojah kabab (chicken) and the traditional drink Doogh (made of yoghurt ).
Take care of yourself & your Camera or Cellphone at boat,
The lake Depth at some places is up to 16m
