Yemin Stream flows from Yemin Plane, east of the great crater (25 minutes of drive from the farm). When the road meets the stream, there is an overnight parking lot where you can leave your vehicle. The stream is dry most year but has three natural pools that accumulate flood water for several weeks.
From the parking lot about 2km and another 2 to the spring. There is a downward slope in the first half of the track and then an upward one in the second, though not a very steep ascent.
