Rainbow Mountain Lush greenery, steamy geothermal sights and pink clay tracks. Rainbow Mountain truly is a volcanic wonderland. About 20 minutes south of Rotorua, this steep but short track between two crater lakes provides stunning mountain views, including Mt Tarawera, the Paeroa Range, the Urewera Ranges, Mt Tauhara and the volcanic peaks of Tongariro National Park. The 5km return trip takes the average walker a couple of hours. However, do not take your furry friend on this one because dogs are not allowed.
