Free spas that exploit the hot water that flows at almost 50° and which then mixes with the waters of the Fosso Bianco; it is precisely along this watercourse that the various pools, basins and waterfalls are found. The Fosso Bianco flows at the edge of the houses of the village (to the east), under via del Fosso Bianco (which branches off from the provincial road 61, at the intersection with via del Bollore and proceeds one-way towards the north; on this street there are car parks which, however, are paid at an hourly rate - alternatively you can leave the car in the few spaces that can be found near the aforementioned intersection, traveling just a few hundred meters more). The (signposted) path begins from Via del Fosso Bianco which, among the vegetation, descends towards the ditch: almost immediately you will come across some pools, but to reach the largest and most scenic part you have to cross the ditch (there is a small bridge) and continue on the path for another 100/200 metres. Here a spectacular scenario will be presented, with a high wall covered with limestone concretions of different colors (but mostly pure white) where among the water that descends, even forming some waterfalls, there are, at various heights, pools and tanks of different width, depth and temperature. Just beyond the point where the water falls from above you will also see a suggestive and enormous limestone formation, partly with the characteristics of the concretions present in karst caves and partly with steps; to preserve its beauty it is forbidden to climb on it: this formation is known as the White Whale (even if white is not the only color present). Mine was a tourist visit and I really liked the environment, an extraordinary sight, without paying anything, not even for parking, having left the car at the aforementioned intersection. To take a bath you must obviously enjoy contact with nature and accept the inconveniences of the lack of services: therefore you move along earthy or muddy/clayey paths, you undress without privacy, you have to find where to put your things, if you For a long time there has been the problem of the lack of toilets, and so on. Also bear in mind that the place is very busy: I was there on a Friday afternoon in early April and there were a lot of people, including many foreigners: Europeans and even Asians. Other thermal water pools are located on the right of Via del Bollore, about 600 meters from its beginning, but these were not the subject of my visit.

After failing to visit the bigger and more popular hot springs Cascade del Mulino which we found overcrowded, we finally could experience the hot springs at the San Filippo. This time we were quite early in the morning though even then there were to my opinion a lot of bathing visitors. After spending a short time in a milky pool we decided to go back to the beginning of the springs because the water there was much warmer and also we were alone there. About half an hour later more people started coming, so it was time to leave. We parked alongside the road, paid €3 for 2 hours, and went down through the forest (after some locals). We didn't even know there was another way and you had to pay. Yes, unfortunately, some trash is left by visitors which is upsetting.

Visited with friends for the day. Lots of people but it was still enjoyable, perhaps because the weather wasn't great. I imagine that on the weekends it's hell. The paid parking lots are very close but expensive; otherwise you can park earlier, along the road, but it is a little further away. Access is free only in the winter months and perhaps until April. There are places just before the path where you can eat or get sandwiches and go to the bathroom but don't change; it's important to arrive in your swimsuit and have rock shoes. No flip flops or slippers because you slip a lot and there is mud everywhere. Given these premises, it is a unique, wonderful place, immersed in the woods, the water has a crazy temperature and the limestone formations are impressive. The photos don't do it justice. Considering the constant influx of wild tourism, the forest is also quite clean

Splendid natural spas which are accessed along a short path with gravel. The show is unique, the source of very hot limestone water slowly cools as it descends forming larger or smaller pools. If you plan to spend the whole day at the San Filippo baths it is advisable to bring food and water. There are no public toilets. The water is calcareous so it dries the skin a lot. It is forbidden to climb the limestone formations to avoid ruining them but unfortunately not everyone respects the environment. That's the only bad thing.

We wanted to do something special and best of all without many tourists. That’s why we went to the “white whale”. A great afternoon in warm water. Since the Rosso bianco is in the middle of the forest and you unfortunately have to walk a little longer. The path is not for people who are not easily influx. Since the place is public and you don't have to pay for admission, there are no seating or changing rooms. This should be taken into account when planning.

Not far from Abbadia San Salvatore, where we were for a few days of vacation, is a magical place. Free access we paid only parking, not far from the site... about 10 minutes. Preferable to go on weekdays to avoid crowds. Go equipped with towels, costume and recommended rock shoes. Bring water and eating if you want to stay all day in the pool area. The water is warm and the limestone formations are real works of art. Great experience.... Relaxing in the pools is priceless. Excursion not to be missed!

A gift from nature, an experience that must be lived absolutely. There is a large influx of people and from what we have heard many are foreigners. Maybe if there was the possibility nearby without disfiguring the natural landscape of a chemical bath and a mobile structure for personal services, since it was thought at the immediate street for access to do it even for a fee!

Natural waterfall immersed in a forest, which forms many lakes of hot and very hot water. What more could you want from a hot spring? It is possible to dive and while sitting, in some tubs, the water reaches your neck. It is necessary to wear 'rock' shoes to move safely on the agglomeration and reach all the pools well

Easy to find activity, free access to sources but paid parking with a parking meter. Warm waters even in November for us, average crowd. Wild places no infrastructure to change.

Great place. That's great. To return even in winter. In September, given the beautiful days, it is still very crowded. Best in winter, when it's colder. You don't risk anything anyway, there are hot thermal baths that refresh the body. Just find a nice day without rain.
