The 2026 summer season kicks off with the Festival of Lights on Saturday 20 June 2026 from 1.45 pm.

On the programme: a version of ‘La Grotte s’enflamme’ (The Cave Ablaze), a temporary installation featuring 1,400 candles set against a backdrop of rock formations, offering visitors a ‘fantastic’ immersion in the underground world! (Included in the Trabuc Cave tour, audio-guided tour, with or without booking). At 6.30 pm, the flames of the carbide lamps take over during the Double Tour. Accompanied by a guide, a 1 hour 40 minute tour in the traditional style awaits you, offering a fun and picturesque exploration of the site (booking required).
