I guess that Dumbledore has been analysing everything he knows about 
TR for quite some years to try and get hints or clues as to where he 
might put the horcruxes and in what relics.  It seemed very clear in 
the book that the cave incident was significant as it was mentioned 
more than once.  I would assume that Dumbledore therefore made a 
connection between that and a possible hiding place for a horcrux.  
He may have made other connections from the past, like the connection 
that some on this site have made between a horcrux and possibly 
Godric's Hollow.  Once he had made the connection all he had to do 
was find the caves location, and once he realised how tricky it was 
to get to it he would probably have realised that it would be a 
perfect hiding place.  As he said, it wasn't easy to find because of 
where it was situated in relation to the beach.  I guess in order to 
track it down he could have examined someone else's memory - maybe on 
eof the two children TR took there and terrorised, or he may have 
just investigated the area as he already knew the place where the 
children had been taken on holiday.  It doesn't specifically state 
how he found the horcrux's location, nor where the ring was found or 
how it was found, nor how the ring horcrux was destroyed and what 
happened.  Maybe these things will come to light.  Snape must know 
the ring story because he saved Dumbledore when he arrived back 'near 
to death'.
