The amenities are definitely Grotta Giusti’s strongest feature. The hotel has one big pool open to the public – only from 10am to 6pm, the rest of the time this pool is exclusively for guests – and two smaller pools reserved for the hotel’s guests. The smaller pool, right next to the spa facilities, is a big jacuzzi with five different types of hydro-massages available.

Finally, the icing on the cake: the famous grotto. Grotta Giusti hides a natural treasure which has won the hotel a few awards (including World’s Best Thermal Grotto Spa at the World Spa Awards 2018) and attracts visitors from around the world.

Entering the natural grotto is like being transported to a fairytale. The ancient thermal cave works as a natural steam room and its divided into three different sections that have been named ‘paradise’, ‘purgatory’ and ‘hell’ as the temperature in the cave rises from 28 to 34 degrees, depending on the zone. The recommended treatment is 50 minutes long but there is more to do in the grotto than just sitting down. For the yogis, Grotta Giusti organises yoga classes in the upper (‘paradise’) part of the cave. The healthy natural vapours help anything from respiratory, circulatory, osteo-muscular, nervous and skin complaints and the warmth makes the yoga experience even more relaxing.

The most magical place in the grotto must be the hot spring lake. This natural wonder is particularly fascinating in the winter, when the water is higher. During this period, the hotel organises scuba diving lessons and floating therapy – a one of a kind experience.
