While the Stones of Stenness are not as numerous as the nearby Ring of Brodgar, this stone circle is much more peaceful. I almost don't want to recommend this as it is the ring's quiet calmness that seeps into you if you take the time to stand and stare. The combination of the size of the stones and the low rolling countryside mean that the circle can be seen from some considerable distance but for me it is the spirituality that you feel when standing within the circle that makes it special.
