Pompeii - Cobblestone streets

Here are some pix:

I didn't find them "daunting" or very difficult at all; just wear a good sturdy shoe and watch where you're going so you don't trip. As you'll see by some of the pix, there are also less-stony paths alongside some of them They're nothing at all like Rome or Paris cobbles as they're much, much older. Sometimes you'll be walking on bare ground or gravel footpaths too.

Now, if you have mobility and balance issues to begin with, you're likely to find the going tougher than we did.

Wear good, comfortable, supportive shoes. Start walking extended distances now, mixing in some trails.

Yes, in some places. Much more difficult anytime you are on the original stone pavement. The large plazas are even and smooth. The photos show you large stones with curved sides, uneven pavement, etc. I live in France and am used to walking on all kinds of stone pavements on a daily basis. Yes, these are more difficult. Wide soled shoes, flat heels, and ankle support if you have weak ankles.

To add to the above...
Looking back at some of your previous posts, you do mention some mobility limitations although you indicate that they're not seriously debilitating. Pompeii has a sightseeing route for visitors using wheelchairs, strollers for wee children and others unable or uncomfortable managing steps and/or more challenging parts of the terrain. The website states that it's the longest accessible pathway through an archaeological site in Italy. This might be a good option for you if worried about being able to enjoy your visit?

Note that the access point for this route is not at the main Porta Marina entrance but at Piazza Anfiteatro (see the map).

"cobblestone" is a convenient but inaccurate shorthand. No two paving stones in Pompeii have the same size, dimensions, level-ness, corners, or angles. Many are chipped or rutted by chariot wheels. It is not helpful to think of modern paving stones laid and maintained by professional masons.

I would compare the Pompeii " sidewalk" and street stones as akin to trail walking. One can't maintain an even gate due to the irregularity of all the stones, and crossing the streets require very high stepping up and down. But Pompeii is amazing, so enjoy!

At the Pompei ruins in 2015, I wiped out while walking backwards on the cobblestones while talking to my wife, who was walking slower than I was.

Note: don't do that!

they aren't cobbles but laid stone that are uneven with centuries of wear. True cobbles are rounded river stones like those leading up to the Alhambra and are VERY hard to walk on without very well cushioned shoes. Most Paris streets that are not concrete are with laid squared stones called setts which are not difficult to walk on. Pompeii roads are larger rectangular blocks of uneven sizes which are often worn and uneven and something of a challenge. If you have real issues you can walk on the route for handicapped people, but most people can manage with good shoes and paying attention.

Thanks for the helpful info, everyone!

I imagine I'm going to get my money's worth out of my Hokas while traveling throughout Italy!
