Here's a photo of my guide standing by some rowing boats moored up by the side of the lake. We took one out for about 30 minutes which was rowed by a young chap from our ger camp. There's not much to see beside or on the lake itself.
Ogyi Nuur, or Ogii Lake, is a large lake located about 65km north of Harhorin and about 300km east of Ulaanbaatar on the road to the Arhangay provincial capital of Tsetserleg. The lake measures a length of about 8km by a width of 5km and has a surface area of 25.7 sq km. I came here on the 4th day of my 12-day tour around Mongolia and stayed the night in a tourist ger camp beside the lake surrounded by horses. The lake is very beautiful and still, with no boats on it.
Our ger camp beside Ogii Lake was surrounded by dozens of horses, some of them very young foals who were a bit dodgy on their legs. The reason why there's so many of them is due to the fact that they belong to a nomadic family nearby. More photos of them can be found in the travelogues.
The restaurant at Ogii Nuur ger camp is a fairly modern looking building. For dinner that evening we had salad for starters followed by mutton with peppers, spaghetti and potatoes all washed down with a bottle of Borgio beer. Breakfast wasn't that good.
