The status of the Laghetto dei Fanghi (mud pool) has changed over time. The commercial Terme di Vulcano facility that previously charged admission closed in early 2020 with plans for redevelopment. However, the natural free mud pool near the port (Pozza dei Fanghi) where thermal water and volcanic mud emerge naturally from underground remains accessible. As of recent reports, this free mud pool area continues to function as a natural thermal phenomenon. Visitors should be aware that in November 2021 and again in October 2025, elevated volcanic gas emissions led to temporary evacuations of port areas and access restrictions due to safety concerns about carbon dioxide and sulfur dioxide levels. The volcanic alert level has fluctuated between normal and yellow (caution) status. Current access status can change based on volcanic monitoring data, so visitors should check current conditions before traveling. When accessible, the mud pool is free and open 24 hours. The Spiaggia delle Fumarole (hot sea beach) with underwater thermal vents heating seawater generally remains accessible even when mud pool access is restricted.

The sulfur smell at Vulcano is exceptionally strong and distinctive, described by many visitors as among the most intense sulfur odors they have ever encountered at any thermal spring worldwide. The smell derives from hydrogen sulfide gas (H2S) released by volcanic fumaroles and dissolved in the thermal waters. Hydrogen sulfide has the characteristic rotten egg smell. At Vulcano, the concentration of sulfurous gases is high enough that many visitors report feeling physically nauseated, experiencing headaches, or finding the smell overwhelming especially on calm windless days when gases accumulate rather than dispersing. The yellow discolored rocks surrounding the mud pool and thermal areas are sulfur deposits that visually mark the intensity of the volcanic gases. Visitors with respiratory sensitivities, asthma, or susceptibility to strong odors should be prepared for this intense smell. The smell permeates clothing and swimwear and can be difficult to remove even after washing. Some visitors recommend bringing old swimsuits specifically for Vulcano and washing them separately. Despite the strong odor, the sulfur is part of the authentic volcanic experience and the therapeutic mineral composition of the waters. Most visitors acclimate to the smell after some time exposure, though it never completely disappears from consciousness.

Vulcano Island is reached by ferry or hydrofoil from Milazzo on Sicily's northeastern coast, which is the main departure point with year-round regular service. From Milazzo port, hydrofoils (aliscafi) take approximately 40 to 50 minutes and operate multiple times daily. Car ferries take approximately 1 to 1.5 hours and allow bringing vehicles to the island. Both vessel types dock at Porto di Levante, the main harbor where the mud pool and thermal beach are located steps away. Multiple ferry companies operate services including Siremar, Liberty Lines, and others with varying schedules and prices. Summer offers the most frequent departures (hourly or more during peak periods) while winter has reduced schedules. Advance booking is recommended during July and August high season. Milazzo is accessible from major Sicilian cities: from Catania (approximately 100 kilometers, 1.5 hours by car or train), from Palermo (approximately 200 kilometers, 2 to 3 hours), and from Messina (approximately 40 kilometers, 45 minutes). Seasonal ferry connections also operate from Naples (7 to 9 hours, mainly summer), Messina (2 to 4 hours depending on stops at other Aeolian islands), and Palermo (summer only). Day trips to Vulcano are very popular, but spending at least one night allows experiencing the thermal springs at different times including early morning or evening when crowds are smaller and the atmosphere is more peaceful.

What should I bring to the Vulcano thermal springs?

While Vulcano's thermal waters are extremely hot at source vents (approaching 90 to 95 degrees Celsius, hot enough to cook food), there are no reports of cooking being a traditional activity at Vulcano's thermal sites as it is at Sorgeto Bay on Ischia. The primary thermal experiences at Vulcano are mud bathing in the Laghetto dei Fanghi and soaking in heated seawater at Spiaggia delle Fumarole, rather than utilizing extremely hot spring vents for cooking. The mud pool itself is too muddy and sulfurous for cooking food, and the underwater fumaroles at the beach heat seawater diffusely rather than creating distinct boiling pools suitable for cooking. Additionally, the elevated volcanic gas emissions (including carbon dioxide, sulfur dioxide, and other volcanic gases) at Vulcano make prolonged close exposure to the hottest fumaroles potentially dangerous. Safety monitoring has led to periodic access restrictions specifically because gas concentrations near the most active fumaroles can reach hazardous levels. For these reasons, cooking in Vulcano's thermal waters is not recommended, not traditionally practiced, and would present both practical difficulties and safety risks. Visitors to Vulcano can enjoy excellent Sicilian and Aeolian cuisine at restaurants in the small Porto di Levante village including fresh seafood, local Malvasia wine, and island specialties.
