Convenient parking is available across from the restaurant, allowing easy access to the Segesta wild hot spring, a short walk away. It may be possible to obtain permission from the restaurant for overnight parking.
The parking spot was great for an overnight stay. We immediately signed up for a pizza dinner, which was delicious. The walk to the hot spring started by turning left from the Rustic pizzeria and continued until reaching the Terme Segestana. Then, turn right and left again and continue until reaching the Fiume river. It's not recommended to take the motorhome as the roads are in poor condition.
There is a parking lot across from the pizza place that is suitable for a few hours, but not for overnight stay due to noise from the highway, roads, trains, and barking dogs. The natural springs are a 10-minute walk away, accessible via a paved road towards the paid thermal baths, passing under a bridge and then following a dirt path behind the baths. However, the springs were disappointing as the pool was small and quickly filled up with only about 10 people, and the water level was low. The path to the springs was dirty, with trash and people loitering along the way.
