Macalube di Aragona in one sentence: A small, moon-like nature reserve near Aragona (Province of Agrigento) with active sedimentary volcanism – cold, clayey mud cones that release gas and mud to the surface. Geologically fascinating, but not a freely accessible destination: after a fatal accident in 2014 in which two children died, access to the actual mud-volcano field is heavily restricted or at times closed, and generally allowed only accompanied. Plan your visit only through the official rules or a guided tour – never enter the core area on your own.
The Macalube di Aragona lie a few kilometres from the city of Agrigento, in the municipality of Aragona. On a bare, clayey rise, numerous small mud cones form a surreal, almost moon-like landscape. Gas, water and viscous mud continually emerge from the cones – a phenomenon known as sedimentary volcanism (colloquially “mud volcanoes”). Unlike true volcanoes, the mud here is cold.
The name “Macalube” is traced back to Arabic and suits the constantly shifting, ever-moving ground. The area is under nature protection; the reserve is managed by the environmental organisation Legambiente. Important for trip planning: the Macalube are less a classic “sightseeing” destination than a sensitive and potentially dangerous natural phenomenon.
A safety note up front: On 27 September 2014, a mud eruption caused a fatal accident in which two children died. Since then, direct access to the mud-volcano field has been strictly regulated – depending on the current situation, it is closed or accessible only accompanied. Do not rely on older travel reports, but only on the official, current rules on site.
Quick Facts
- Location municipality of Aragona, Province of Agrigento; a few kilometres from Agrigento
- What it is a nature reserve with active sedimentary volcanism (cold mud cones)
- Landscape a bare, moon-like clay area with small, constantly active mud volcanoes
- Access heavily restricted; core area at times closed or accessible only accompanied – follow the official rules
- Safety after a fatal accident in 2014 (two children), no unaccompanied entry into the field
- Car getting there is really only practical by car
- Best time spring & autumn; shadeless and hot in high summer
- Who it suits those interested in geology and nature; not for a spontaneous walk into the field
Who is a visit worth it for? (Decision guide)
| Traveller type | Well suited | Limitations |
|---|---|---|
| Geology & nature | a rare sedimentary-volcanism phenomenon, a moon-like landscape | the core area is accessible only in a restricted way / accompanied |
| Photography | unusual shapes, a wide bare area, distinctive light | no shade; don’t enter the field on your own |
| Families | a short nature excursion off the tourist trail | potentially dangerous terrain – don’t let children into the field |
| Combined trip with Agrigento | combines well with the Valley of the Temples | only sensibly reachable by car |
| Low-mobility access | – | unpaved, clayey terrain; not accessible for limited mobility |
The natural phenomenon in detail
How the mud volcanoes form
Beneath the surface, water, fine clay and rising gas mix together. This mixture works its way upward and emerges at numerous spots as viscous, cold mud. This is how the characteristic small cones form, bubbling and expelling material at irregular intervals. Because the mud is cold, this is not true (magmatic) volcanism but sedimentary volcanism.
The moon-like landscape
The result is a largely vegetation-free, grey to ochre-coloured area with small craters and rivulets – a sight often compared to a lunar landscape. It’s precisely this contrast with Sicily’s otherwise green surroundings that gives the area its appeal.
Activity and change
The Macalube are not a static sight: the cones change, some dry up, others form anew. In rarer cases, stronger, sudden mud eruptions can occur. This very unpredictability is the reason for the strict access rules.
Getting there, access & safety
Getting there: The reserve lies in the municipality of Aragona, a few kilometres from Agrigento. It’s really only practical to reach by car; a dedicated parking/entrance area serves as the starting point. Public transport connections are irregular.
Access to the mud-volcano field: Direct access to the actual Macalube field is heavily restricted. Depending on the current assessment, the core area is at times closed or accessible only accompanied – for example as part of an official guided tour. Whether, when and under what conditions entry is possible is determined by the responsible authority on site.
Safety: The background to these restrictions is a fatal accident on 27 September 2014, in which a mud eruption killed two children. Never enter the field on your own or off the marked paths. Strictly follow barriers, warning signs and instructions on site, and inform yourself in advance about the current rules and any available guided tours. We deliberately don’t offer our own risk or access forecast here – only the official, current information on site is authoritative.
Common mistakes
- Entering the mud-volcano field on your own instead of waiting for the official rules or a guided tour.
- Relying on older travel reports that describe free access.
- Going into the shadeless, clayey terrain without water, sun protection and sturdy footwear.
- Letting children or dogs near the cones unsupervised.
- Planning the visit for the midday heat of high summer.

- Valley of the Temples (Agrigento) – the famous archaeological World Heritage site, combines well with the Macalube.

Frequently Asked Questions
Are the Macalube real volcanoes?
No. This is sedimentary volcanism: water, clay and gas emerge as cold mud and form small cones. There is no true (magmatic) volcanism with hot lava involved.
Can you freely enter the mud-volcano field?
No, not freely. Access to the actual field is heavily restricted – depending on the situation, it’s closed or accessible only accompanied. The official, current rules on site are what apply; entering on your own is not permitted.
Why is access restricted?
On 27 September 2014, a mud eruption caused a fatal accident in which two children died. Strict access rules have applied ever since to protect visitors. The cones’ activity is unpredictable.
Where are the Macalube and how do you get there?
They lie in the municipality of Aragona in the Province of Agrigento, a few kilometres from Agrigento. Getting there is really only practical by car.
Is it worth combining the visit with Agrigento?
Yes. The Macalube combine well with the Valley of the Temples and the city of Agrigento for a day in the region – provided access to the reserve is possible at the time you want to visit.
