Cueva de Nerja — Free Entry (Sunday Afternoon)

The Nerja Cave, one of the largest karst cave systems in Europe, opens to EU citizens without charge on Sunday afternoons. Bring ID to prove EU citizenship at the entrance. The visit takes in the cave’s show galleries and the on-site museum, which covers the Palaeolithic finds made here.

There’s no need to book — just turn up within the window and show your passport or ID card at the ticket desk.
