Today I visited this location from Baku by busses and minibuses plus unexpected walks as the bus I needed (bus 134) does not seem to go at the moment. I visited the lake at the coordinates the other review mentions (40.467668, 49.801180). The approach is not the nicest as one has to walk through a garbage dump to reach the shore. The lake itself doesn't look like asphalt, but rather somewhat clean water. The large amount of vegetation and the clean (bar the rubbish) soil also makes me wonder whether there was any asphalt here in recent years. After a quick look and a few photos I went towards the lake hotel and then approached the Keyraki mud volcano from the back side, There are several paths up. I chose the first one and enjoyed looking at the crater and mud flows of the 2017 eruption. The wind at the top was very strong and I really had to pay attention to not fall into a crack in the surface of the vulcano. I really enjoyed the views from the top. The Mirzaladi and Masazir salt lakes were very clearly visible, as was Binagadi. Also didn't look like a tar pit from the top. However, past the lake hotel I was smelling a very strong asphalt smell. Maybe a lot of it had been pumped off? No idea. While it's not the most interesting location overall I really did enjoy this trip from Baku, and the mud volcano.
