The Geyser Valley of Wairakei is one of the most marvellous creations of its kind to be found perhaps in any part of the world. It forms, as it were, one of the principal arteries of thermal action which would seem to extend from the volcano of Tongariro in the south through the Lake region to Whakari, the active crater in the Bay of Plenty, in the east. The bottom of the valley is situated at an elevation of 1000 feet above the level of the sea, while down its centre, which has a gradual fall to the east, a warm stream of water, known as Te Wairakei, flows rapidly on its course to join the Waikato. Its steep, winding sides rise in some places to a height of over 200 feet, and above these again flat terraces spread out, bounded by clusters of conical, fern-clad hills, which mount upward, as it were, in increasing elevation to the heights beyond. Looking down the valley from one of the elevations, one sees the winding course of the great fissure filled with a dense growth of vegetation, forced into vigorous life, as it were, by the white clouds of steam that mount into the air on every side. There is one great charm about the Geyser Valley of Wairakei, and that is that it is not a melancholy, dismal-looking place. It has not the Hades-like appearance of Tikitere nor the Valley-of-Death-like look of Whakarewarewa. One is at once struck with the varied growth of vegetation which everywhere abounds, the luxuriance of the trees, the rich beauty of the ferns, and the vivid green of the thick carpet of rare and beautiful mosses which spreads itself everywhere about, from the margin of the stream below to the very tops of the steep, smoking cliffs. Every geyser, spring, and mud-hole has its clustering vegetation, and as you grope your way through the thick undergrowth along the tortuous stream, each thermal wonder bursts suddenly upon the view with a fresh and startling beauty. As we descended into the valley by a tortuous pathway we heard the rushing of waters below, as the turbulent stream beneath swept onward over a series of miniature cascades; then the noise of hissing steam burst upon the ear, the heated ground seemed to quake beneath our feet, the boiling mud-holes sent forth a noise like the incessant "thud" of a steam-hammer, which mingled in a weird way with the loud roar and splashing of the geysers as they threw up their columns of boiling water above the trees.
