Boats travelling up and down Anduin and Lorien's isolation.

Actually, Men other than those of Dale seem to have had some measure of contact with Lórien Elves.

For one thing, Haldir noted that he knew the Common Speech because 'there are some of us still who go abroad for news and the watching of our enemies, and they speak the languages of other lands'. I further posit that Lórien had occasional encounters with Men from Gondor, based on Faramir's words to Frodo.

'Yet there are among us still some who have dealing with the Elves when they may, and ever and anon one will go in secret to Lórien, seldom to return.'

I wouldn't think the intercourse was a common thing, but both Lórien and Gondor seem to have derived some benefit from it, else it would have stopped altogether.
