We visited this site in Feb 2022 en route from the Mani peninsula to Olympia. I would definitely recommend a visit and a car to get there. Our GPS took us there via some rather obscure back roads and our first glimpse of the site was from above as we came down from the mountain to the east. Our visit on site was equally pleasant as the ruins are well kept and laid out. I think what I liked the most was that each element of the former city is spaced out and clearly identifiable and I could get a feel for the full layout without getting an impression of clutter or trying to cut through more modern development like most other ruins. As mentioned in the previous reviews the best is saved for last. At the far end is the fantastic stadium. 

As well presented as the site is there is still evidence of much more left to be uncovered. The nearby museum is small with just a few local artifacts. As for the fortifications, it is possible to see some elements of the walls in the distance from the ruins. We left by driving to the west and after a km or so passed through the large Arcadian gate and got a good look at the walls.

This should be an easy addition to the WHS list if Greece ever decides to submit it.
