Wai-o-Tapu is small in size – only 18 square kilometers – but it is densely packed with all kinds of geothermal attractions. Here, the underground forces of nature burst to the surface in many of the most spectacular ways: hot springs are bubbling everywhere, fumaroles are smoking, mud ponds are bubbling; lakes of the most unimaginable colors are visible in numerous craters and sinkholes; an almost real geyser erupts once a day.Since 1931, there has been a landscape reserve in Wai-o-Tapu. The most picturesque part of it is managed by a private commercial enterprise "Wai-o-Tapu Thermal Wonderland" under a concession agreement. At the entrance, visitors are given a detailed guide map. It identifies and describes in detail all 25 geothermal facilities of the park, which are accessed by three landscaped hiking trails.
