A traditional cache located along the Thames Path.
The cache is on the Thames side of the path so be alert if caching with children.
Hard to tell which Greek nymph would be associated with the Thames here in Barnes. The Nereids are associate with the sea while the Naiads are the spirits presiding over fresh water. The Thames is a tidal river from the sea to Teddington so the water here is brackish.
As always with the Thames path, tree cover is a problem. This is also a busy stretch of the tow path so I'll make it easy for you to find. Check the 'view from the cache' photo. The cache is attached so don't yank it toward you. Be nice to the nymphs.
Please don't include photos or any more hints in your log or I'll remove them.
