This MUST be on your bucket list but do your best to get there as early as possible. We found the most efficient way was by coach. Ask the tour companies to give you a transfer rate of 39 euros (not printed in the catalog!). The walking tour costs much more. The maps they hand out on the premises are not very well marked so do your best to meander in a methodical way so you don't miss the spectacular plantings.
