Vrata Ada (gates of hell) are two deep pits located next to the Mudpots Platform. Its gloomy vaults are going somewhere deep into the Earth, the insides are hidden behind the clouds of steam. You can hear low dull noises coming from the depths of these pits, sometimes almost resembling heavy sighs.
Scary look of this place was noted by the first tourists, who dubbed it Vrata Ada (gates of hell).
