Had a good look around today...and despite the fact that we have had loads of rain I can see no sign of a spring that may have fed a well up on the tor. The only building remains I would think belong to some small scale quarrying.
If you would still like to visit the tor...and it is worth it on a fine day for the views...I would approach from the north taking in the Colvannick Stone Row on the way. You can park just off the A30 at Temple fisheries and walk from there.
There is a firing range in the area but it is not used that often and posts tell you where you can and can not go.

Just to add a little to this posting...I am busy researching this area and the mysteries surrounding the tor, its well, chapel and name. I think I may have found the well but am waiting for better weather to go and take a good look.
Not only is this a disputed site antiquarian wise..I would go so far as to say that it is a disputed site full stop.
It is mentioned in "Ancient and Holy Wells of Cornwall" Quiller-Couch 1894, but was the well ever seen? I am sure there is no well up there now (I can't find it) and Axford in his book on Bodmin Moor published in 1975 says "Only one holy well is recorded on the moor. This WAS at St Bellarmin's Tor.." he goes on to say that the QC sisters reported that there "was no more distinct traces of masonry than a few stones lying around". These are now thought to come from an sheep fold..not a medieval chapel as earlier thought.
So was there ever a well? ...and was there ever a St Bellarmin in Cornwall? I've yet to find any proof.
