In this page, I’ll explain how the summer ZTL (Limited Traffic Zone) for accessing the harbour and town of Porto Ercole works. It’s important to understand how it works, which access points are monitored by cameras, and on which dates and times it is forbidden for cars without an access permit to enter the harbour and town. In my opinion, the signs are not very clear to a visitor, especially for foreign tourists, and getting hefty fines is quite easy.
So, let’s look at:
Like all the pages on this site, all my advice comes from personal experience: I also received a fine for a wrong entry into the ZTL, despite knowing the town very well and having visited Porto Ercole regularly for several decades. This proves that it is important to properly inform anyone who wants to visit Porto Ercole, as it is not very clear how these ZTLs work.
dates, times and rules of the ZTLs
For several years, a Limited Traffic Zone has been in effect in Porto Ercole, blocking access to the harbour area, namely the Lungomare Andrea Doria. However, from 2024, a ZTL that completely closes access to the town on the busiest summer days (all of August and a large part of July) is also active.
To put it simply:
More precisely, this is the text of ordinance 158/2025 which regulates the two ZTLs in Porto Ercole for the year 2025:
(I have highlighted the parts in red)
ZTL – TOWN – Porto Ercole
Access to the “ZTL PAESE in Porto Ercole”, at the 3 gates located in:
1. Viale Caravaggio – intersection with Piazzale Vespucci
2. Via dei Molini – intersection with Via Campagnatico
3. Viale Caravaggio – intersection with Piazza Ricasoli
will be allowed exclusively to vehicles referred to in ordinance no. 212/2024, no. 231/2024, no. 56/2025, in the time slot 18:00-24:00 on the following periods:
Month of June, days 1-2-6-7-8-13-14-15-50-21-22-27-28-29
Month of July, days 4-5-6-11-12-13-18-19-20-25-26-27
Month of August, every day.
ZTL – HARBOUR in Porto Ercole
Access to the “Porto” ZTL in Porto Ercole, (gates 1 and 3) will be allowed exclusively to
vehicles referred to in ordinance no. 56 of 06/03/2025, authorised for the respective gates, in the time slot: from 18:00 to 24:00 according to the following calendar:
Month of June, days 1-2-6-7-8-13-14-15-20-21-22-27-28-29.
Month of July and August every day.
Month of September, days 5-6-7.
N.B. The dates reported in the ordinance are for the 2025 calendar, but essentially it means:
- every Friday, Saturday and Sunday in July (and June for the harbour ZTL)
- every day in August
ATTENTION! The “gates 1 and 3” of the harbour ZTL referred to in the ordinance are NOT those numbered 1 and 3 in the previous point: instead, it refers to the numbering of the gates as it appears on the signs on the access roads to the harbour. I refer you to the streetview harbour access section where the street view images actually show these wordings on the signs.
To better understand where the cameras controlling the access points are located, below I provide both a custom map and street views to understand what you will see (and what details to pay attention to) from your car when you arrive:
the map of the access points
To help you visualise more clearly where the main access gates are, I have created this custom map that shows them clearly: zoom in on the various points to understand exactly where the camera-controlled access gates are. As you zoom in, you will see that the dots become lines that make it clearer where the gates are (they are the lines not to be crossed).
On the map
- in purple are the gates for the town ZTL
- in blue are the gates for the harbour ZTL
To be even clearer, here are the Google street view images below to help you visually understand where the harbour and town ZTL access points are, and specifically which panel you need to look at to see if you can enter at the moment you arrive:
streetview of the town access
The vast majority of visitors arrive in Porto Ercole following the main road from Orbetello. So, after passing the A Point Porto Ercole Resort & Spa hotel on your right and the first houses of the town, you will almost certainly find yourself on V.le Caravaggio at the intersection with Piazza A. Vespucci (on the right in the image below, it’s the square with the main car park at the entrance to the town) at the point shown in this street view:
click on the image to access the interactive street view
If you follow the yellow arrow, you enter the town, but to do so without getting a fine, FIRST you must check that the electronic display highlighted in yellow shows the words “ZTL non attiva” (ZTL not active). If, however, it shows the red message “ZTL attiva” (ZTL active), you CANNOT enter the town, otherwise you will get a fine because the camera outlined in orange will read your car’s number plate, and when the data is sent to the Municipal Police command in Porto Santo Stefano, they will check that your plate is not associated with a valid permit and will send you a fine (it should be around €90-100 per fine + notification costs).
So if the ZTL is active and the sign is red, you must turn right and park your car in the car park in Piazza A. Vespucci. If you can’t find a space in the square’s car park (which is not so unlikely on busy summer days), you can try looking for a space in the side streets highlighted in red in this zoom of the Porto Ercole parking sign:
The problem, however, is that those on-street parking spaces are usually always full because they are used by the houses in the vicinity.
From the car park to the town centre is only a 10-minute walk:
The other camera-controlled access gate is on the other side of the town, in Piazza Ricasoli (the square giving access to the old town), at the hairpin bend that goes up towards the Hotel la Roqqa and the Spanish fortress.
This is the street view image:

When this street view was recorded, cameras and signs had not yet been installed. Now, where the yellow rectangle is in the image, you will find the ZTL signs and the electronic display indicating whether the ZTL is active or not:
As in the other cases
The third access gate is located not far from the first, where the road from Forte Stella joins Via dei Molini: see street view, which in this case is also old and does not show the recently installed signs and cameras.
In addition to the town ZTL access points, let’s also look at the harbour ZTL access points:
streetview of the harbour access
The main access to the Porto Ercole seafront is controlled by the “ZTL porto” access cameras located at the intersection of via fosso delle buche with via Caravaggio. You will most likely enter the town coming from Orbetello, so you will be on the main road, via Caravaggio, and near the church (which will be on your right, not visible in the image below but it is to the right of the white van on the right side of the image) you will face this situation: turning left (yellow arrow) would take you onto via fosso delle buche which leads to the Lungomare Andrea Doria, but BEFORE turning, you must check that the message on the electronic display outlined in yellow is green and says “ZTL non attiva” (ZTL not active).
As in this street view image:
click on the image to access the interactive street view
The display you need to check is the one outlined in yellow: if the red message “ZTL attiva” (ZTL active) appears, you CANNOT enter (assuming you do not have the ZTL harbour access permit). You will find detailed information on the sign outlined in red. The camera that reads your number plate is the one outlined in orange.
Then there is a second possible access to the harbour located at the end of via S. Sebastiano at the junction where you have to decide whether to go left and up via Italia to return to V.le Caravaggio or turn right and go under the arch that leads to the Lungomare Strozzi on the harbour (map).
In this Google Street View, the yellow arrow indicates the direction to go to the harbour (you pass under a bridge arch between the houses) and the ZTL signs are outlined in yellow on the left:
click on the image to access the interactive street view
ATTENTION! The electronic display that signals in green or red whether the ZTL is off or on has been very intelligently placed on the wall BEHIND the signs outlined in yellow on the right of the image. In fact, you can barely see a small portion of the display with the green text if you look carefully at the right side of the yellow-outlined area.
It’s hard to see if you pay close attention while looking at a static photo where I have clearly highlighted where to look… imagine what a foreign tourist who comes to Porto Ercole for the first time and knows nothing about it can understand, because this information is nowhere to be found on the official council websites:
ZTLs not highlighted on official websites
I agree that it is right to limit car access during peak hours on the busiest summer days, also because it would be absolutely pointless to let all cars in during the hours when the town is overcrowded, creating a useless traffic jam with highly stressed drivers going around in circles looking for a non-existent parking space. The best solution is to ban access during peak times and have people park outside the town, since as seen before, with a short 10-minute walk you are in the town centre. Good.
However, the objective of ZTLs and various municipal and state ordinances (such as speed limits) should be to better manage the lives of citizens: ZTLs should not be established to issue fines left and right to make money.
Therefore, in my opinion
For example, as of 1st August 2025, on the homepages and main menus of the official websites of the Municipality of Monte Argentario and the Argentario tourist board, there was no clear and evident information about the two ZTLs that block car access to the town of Porto Ercole.
This is a screenshot taken on 1st August 2025 of the “Vivere il comune” (Living in the municipality) menu:
Information on the ZTL can only be found by searching for “ZTL Porto Ercole” in “cerca nel sito” (search the site): this way you discover that at the bottom of the “rubriche” (sections) sub-section of the “vivere il comune” section, there is indeed a timid menu item that links to a page on the ZTL:
And by clicking on the ZTL page of the Municipality of Monte Argentario you finally get to the page with the official information from the council. Which, however, is basically limited to the text of the ordinance that I quoted in italics at the beginning of this page, without any other useful explanation.
It is highly appreciated that the site is also translated into English, French and German, showing sensitivity and attention to foreign tourists from a small municipality that lives largely on tourism. Good. But let’s say that I consider it highly unlikely that a foreign tourist will manage to find the ZTL page on their own and then make any sense of it. Even the most attentive German tourist would probably find it difficult to search the council website for “ordinanze ZTL Porto Ercole”.
Then there’s the argentarioturismo.it website, which is graphically pleasing and provides a lot of interesting information for those who want to visit Argentario, but here too, there is no information about the ZTL. That site certainly encourages you to come to Argentario, which is objectively a splendid destination, but it doesn’t tell the potential tourist “look, if you come by car on the evenings of a large part of July and all of August and you don’t figure out on your own what you have to do, then the council will fine you without mercy.”
I believe there is room for improvement not only in providing advance information to tourists, but also and especially in the physical and direct control of access: instead of just putting electronic displays placed only at the threshold of the gate, so that a person who doesn’t already have a clear idea of how the system works will almost certainly proceed straight ahead, even just due to reflexes and mental processing times, especially for the ZTLs blocking access to the town, it would definitely be a good idea to have municipal police officers at the gates to stop unsuspecting drivers, explain how it works, and immediately direct them to the car park outside the town. In my opinion, this is the best approach that solves the problem.
Instead, when I passed the main town access gate for the first time, there was no one there, it was dark because it was evening, I had absolutely no idea what that red display with the ZTL active sign was, in a position that I didn’t know was an access gate, and by the time I had processed the information and started to wonder “could there be a new ZTL that no one has ever told me about and for which I haven’t seen any clear signs in the town?!” I had already passed, and the camera had already recorded my number plate, which at the time of transit was not associated with any permit, since I hadn’t applied for one, as I had no idea I needed to. And I have known the town very well for several decades: what do you think will happen to the many foreign tourists if they are not adequately informed?
If you also think that this idea of placing municipal police officers at the summer town ZTL access gates is a good idea
Or suggest a better idea.
As things stand, it only generates useless and, above all, counterproductive resentment for the necessary tourism that the municipality needs to survive: there are testimonies of tourists who were furious, heard shouting on the phone to friends and acquaintances not to come to Porto Ercole at all because it is a town where you get hefty surprise fines. In addition to various other colourful expressions that are best not repeated. That negative word-of-mouth will travel faster than the glossy slogan “Argentario, the diamond of the Mediterranean”.
who to ask for information
On this page about the ZTLs in Porto Ercole, I have tried to provide all the necessary information as clearly as possible. If there are other doubts or questions, I recommend contacting the council directly.
In particular, right on the signs placed at the ZTL gates (look at the photo I inserted earlier), there is an invitation to call the municipal police office directly for more information:
- Local Police Office of the Municipality of Monte Argentario
Phone: +39 0564 812520
email: cpm@comune.monteargentario.gr.it
Other council contacts can be found on this contacts page of the council’s website.
I recommend contacting the municipal police for information about the ZTL.
For tourist information to organise your trip, you can also contact:
- Tourist Information Office
of Porto Ercole
Phone: +39 0564 811982
These are the opening hours of the Tourist Information Office:
from 6 April to 31 May:
every Saturday and Sunday 09:30-12:30 15:30-18:30;
from 1 June to 12 June:
every day 08:00-13:00 16:00-22:00;
from 13 June to 14 September:
every day 09:30-12:30 17:00-20:00 and 20:00-23:00;
from 15 September to 30 September:
every day 08:00-13:00 16:00-22:00;
from 1 October to 30 November:
every Saturday and Sunday 09:30-12:30 15:30-18:30
I must say that both at the municipal police office in Porto Santo Stefano and at the tourist information office in Porto Ercole, they are always very kind, professional, and very helpful.
how to get the permit
If you are a tourist and want to book accommodation in Porto Ercole that guarantees you both a parking space and access to the ZTL, you must check carefully with the owner of the flat or the hotel where you will be staying:
For more information, ask the Municipal Police (see previous paragraph).
what to do in case of fines
If you realised you have accidentally passed through a gate that had the red “ZTL Attiva” sign, you only have two options:
- If you were somehow entitled to a permit associated with your car’s number plate that would have allowed you to access the ZTL (see previous paragraph), go and get it immediately the next day at the council counter on Piazza Roma (see previous paragraph again).
- If, on the other hand, you were not entitled to the permit… you have to resign yourself to paying the fine.
However, I recommend you contact the Municipal Police Office (see above) to ask for information: for example, if you pay quickly, you might be entitled to pay a reduced amount, but you must ask them.
If you have received one or more fines and you find them unfair because you were not sufficiently informed, I advise you to report it to the Public Relations Office (URP) of the council. You will still have to pay the fines, but you can point out that they should better explain to tourists how the ZTLs work, for example by placing Municipal Police officers at the gates when they are active, and by making the information more prominent on the websites.
final tips
In addition to planning all the details of your trip to Porto Ercole well in advance, my final advice should now be obvious:
Apart from the parking and ZTL problem, the town is usually overcrowded anyway, so much so that in the end you don’t enjoy your holiday.
At least that’s how it used to be: perhaps the mayor will really succeed with this application of the ZTLs in completely discouraging visitors from coming to Porto Ercole in August. If he really succeeds, he will make the town quieter and more liveable. But then it would be interesting to see what the various merchants who live only on summer tourism will say to him.
