Our Assessment

Why we recommend Grotta Giusti.

A 19th century villa above a natural thermal grotto with an underground lake.

The steam grotto with its zones Paradiso, Purgatorio and Inferno is unique in Europe; above it sits the Giusti family villa with park and thermal pool. We know the resort from our own journey through Tuscany.

Climate & best time to travel

When it rewards you most.

Best time to travel April to June and September to October for mild, clear days.

Tuscany carries the whole year: mild in spring and autumn, thermally warmed in winter.

  • April to June Spring with green hills, 18 to 26 degrees, ideal for thermal baths and excursions.
  • July to August High summer, often above 30 degrees; early mornings and evenings in the outdoor pools are the finest hours.
  • September to October Harvest season with soft light, 18 to 27 degrees; wine and truffle arrive at the table.
  • November to March Cool, quiet months; the thermal springs of 34 to 42 degrees now show their full effect.

Mai Chau, Northern Vietnam

Avana Retreat

Tucked into the mountains north of Hanoi — the most coherent retreat for experiencing the real northern Vietnam far from the coastal circuit.

Best season October to April — the dry season brings clear mountain mornings and good visibility. In September the rice fields are at their greenest, though rain is possible.

Kerala & South India

CGH Earth

A hotel group that understands southern India is meant to be experienced, not merely visited — the most considered way to move through Kerala and its neighbouring regions.

Best season October to March — outside the monsoon. November to February is the quietest and most comfortable period for Kerala.

Shillim, Pune District

Dharana at Shillim

Dharana at Shillim is not a wellness hotel that happens to be in the mountains — the Sahyadri landscape is the programme. An Ayurveda and yoga retreat anchored in a natural setting that is rare in India.

Best season October to March. The monsoon (June to September) brings intense rainfall and a dramatic landscape — compelling for nature-oriented guests but climatically demanding.
