The cave was remodelled for visitors between 1922 and 1935: a new entrance was made, paths were designed and ladders built. An electrical lighting plan designed by the engineer Carles Buigas was also installed.
Tours take around one hour and follow a 1.2 km path. The tour includes a classical music concert and a boat trip across Lake Martel. The temperature inside is around 21ºC, with a relative humidity of 80%.
The live concert lasts 10 minutes and is played by a quartet of musicians. This is followed by a light effect imitating the sunrise over the lake. Then there is an opportunity to take a short boat trip across the lake or to continue on foot across the bridge.
The lands on which the caves are found date back to the Miocene period, and water seeping through cracks formed the shapes inside, composed of calcium carbonate together with minerals that were swept down from the surface, allowing visitors to appreciate the different shades that appear in them.
The formations that hang from the ceiling are stalactites and those that rise from the ground are stalagmites. You can also make out columns, walls and root-like stalactites. Lake Martel is around 170 metres long, and its depth varies between four and 12 metres. The cave is around 25 metres deep. The stalactites are growing at a rate of around 1 cm per 100 years.
