How to visit the Su Marmuri cave in Ulassai: opening times, prices, how to get there and practical tips from someone who lives minutes from the entrance.
One of the largest caves in Europe is located in Ulassai, about 20 minutes from Villa Pelau: the Su Marmuri cave is one of the most recommended stops for anyone staying in Ogliastra, especially on the hottest days or the rare rainy ones, thanks to its constant year-round internal temperature.
Locals often recommend it to anyone looking for a change from the beach for half a day, or wanting to combine the visit with a stop in Ulassai, between the cave and the Stazione dell'Arte dedicated to Maria Lai.
What to see inside
The guided route runs through one of Sardinia's most impressive cavities, with large chambers, stalactites and stalagmites, and a route fitted with walkways and lighting designed for a wide audience, families with children included.

Practical tips from a local
- Bring a light jumper: even at the height of summer, it's cooler inside the cave than outside.
- Wear closed, comfortable shoes: the route is fitted out, but some stretches can be damp.
- Combine the visit with the village of Ulassai: the Stazione dell'Arte, dedicated to Maria Lai, is a few minutes from the cave — a great addition to complete your morning or afternoon.
- Rainy days: this is one of the best activities for when the coastal weather isn't at its best — the cave experience doesn't depend on the weather outside.
After the visit, the drive back to the sea or the villa takes just a few minutes: Ulassai's location makes it an easy stop to fit into any day of your Ogliastra holiday.
