About Saturnia Hot Springs

Saturnia’s waters maintain a steady temperature of 37°C (99°F) year-round, making them perfect for a warm soak in any season. Rich in sulfur, calcium, and magnesium, these waters have been celebrated since Roman times for their supposed therapeutic properties, including improved circulation and skin health.

The most photographed site is Cascate del Mulino, a series of natural travertine pools where water cascades over soft, white rock into warm, blue-green pools. Legend has it that the springs were created when Jupiter struck the earth with a thunderbolt, gifting Saturnia with its magical waters.


Free Natural Pools vs. Paid Spa

It’s important to know that Saturnia offers two types of experiences:

  1. Free Natural Pools (Cascate del Mulino)
    • Open 24/7, no entry fee.
    • Rustic and wild, with minimal facilities.
    • Can get crowded in peak hours.
  2. Paid Spa Complex (Terme di Saturnia & Natural Spa Resort)
    • Offers full-service spa treatments, changing rooms, and upscale amenities.
    • Entrance fees apply, usually with reservation.
    • Ideal for travelers seeking a structured wellness experience.

Planning Your Visit to Casacate del Mulino

Best Time to Go

  • Early morning (before 7 AM) or late afternoon for fewer crowds.
  • Spring and autumn offer pleasant weather and lighter visitor numbers.

What to Bring

  • Water shoes or sandals for slippery rocks.
  • Bathing suit, towel, and optional swim cap.
  • Light picnic or snacks if visiting the free pools (no alcohol).
  • Refillable water bottle and sun protection.

Facilities

  • Free pools: limited or seasonal amenities; toilets nearby.
  • Paid spa: showers, changing rooms, lounges, and cafés.
  • Parking is available but can require a short walk to the springs.

Tips for Visiting Cascate del Mulino

  • visit the hot springs at sunrise or sunset to avoid the crowds and enjoy a more relaxing experience
  • be prepared for the faint egg-like smell due to the sulfurous water 
  • wear water shoes as there are lots of stones on the bottom of the pools

These sleek Speedo Surfknit Pro feel like you are slipping into a second skin—and the sturdy outsole designed for secure traction provides security.

These Teva Hurricane Drift sandal have a molded silhouette for comfort—and they are so lightweight, it’s like going barefoot—and the matching colors of the straps and soles give off a sleek look.

  • don’t wear jewelry as it can get tarnished from the minerals and sulphur in the water
  • don’t bring valuables or bring a waterproof bag as it’s hard to watch your stuff while in the pools
  • bring sunscreen as there is no shade
  • do not confuse Cascate del Mulino with Terme di Saturnia

Where to Stay in Saturnia

We loved our overnight stay at Villa Acquaviva Wine Resort—the peaceful atmosphere, spotless rooms, stunning views, and a breakfast with plenty of options made it perfect, and the staff was incredibly welcoming. For dinner, we enjoyed a delicious meal at Lo Scangeo’s outdoor tables, overlooking the beautiful Fiora Valley and surrounding mountains.


Our bag with towels and incidentals was nestled in the garden behind me. The path leads to the toilets and changing rooms.


Until next time…
