River Valley is an adventure company that operates from River Valley Lodge, an Adventure Lodge situated 32 kilometers east of the central North Island town of Taihape. What is River Valley all about? River Valley is all about rafts and horses. In fact 3 generations (since 1982)of guides have brought adventures based around river rafting and horse back riding to the general public. Rafting ranges in duration from half day Grade 5 trips on the Rangitikei River - often called one of the world's top half day Grade 5 trips - to gentle floats in the midst of spectacular scenery on our Scenic rafting trips. Horse Trekking. The core of the River Valley Stables riding experience is the natural horse training techniques used to train our horses. This produces horses that are responsive and happy. All riding takes place over the beautiful hill country of this area - the northern Rangitikei.
