Cave sights in Trieste

  1. Grotta Gigante

    The Grotta Gigante is near Villa Opicina, 5km northeast of Trieste. At 107m high, 280m long and 65m wide, the ‘giant grotto’ is one of the continent’s largest accessible caves – St Peter’s Basilica in Rome could fit inside. Nearly 500 steps lead you down into its eerily lit vault replete with stunning stalagmites. Take bus 42 from Piazza Oberdan, or tram 2 – the scenic choice that has covered the 5.2km journey since 1902 – to Villa Opicina, then bus 42 to the cave.
