The Waitomo Caves are a longtime tourist magnet, thanks to their bioluminescent glow-worms and spectacular stalagmite and stalactite formations. Aside from the glories of the caves, this National Film Unit tourism film mentions the surrounding countryside as “a good reason to stay another day”. Set to a laid-back jazz score, a tour from Waitomo Caves Hotel takes in lambing, limestone outcrops, scenic driving and a picnic by the Marokopa waterfalls. But "to float down the underground river as galaxies pass silently overhead is the crowning pleasure in the valley of Waitomo.”
