1. A climbing route setting assembly comprising: a) a route setting guide having at least one climbing route setting map with an x, y coordinate, handhold selection and hand hold orientation system and at least one climbing path, each said climbing path having a plurality of specified x, y coordinate positions and indicia for identifying hand hold selection, mounting position and orientation to form said climbing path on a climbing wall having a corresponding x,y coordinate system; b) a rigid climbing wall having a predetermined x,y coordinate system to correspond with said x,y coordinate, hand hold selection and handhold orientation system of said route setting guide, said predetermined x,y coordinate system of said climbing wall being formed by a plurality of predetermined hand hold mounting apertures at interstices formed by said x, y coordinate system, each said climbing wall mounting position of said rigid climbing wall having attachment means therein to receive a hand hold structure, and to permit handhold rotation about each said hand hold mounting aperture, wherein said interstices of said x, y coordinate system of said climbing wall with respect to said mounting apertures correspond to said specified x, y coordinate positions of said route setting guide for identifying hand hold selection, mounting position and orientation; c) a plurality of hand hold structures, each having a gripping surface and fastening means for securing the hand hold structure to said climbing wall at said mounting positions of said rigid climbing wall, said fastening means providing rotational movement of each said handhold structure with respect to said handhold mounting position aperture to orient said gripping surface of each said handhold, each said hand hold structure having a specified positioning indicia as shown in the route setting map of said route setting guide, said specified positioning indicia including a rotational position of said handhold structure with respect to said x,y coordinate position, said positioning indicia being related to said specified x, y positions of said route setting guide, and said x,y coordinate system of said climbing wall and wherein each said hand hold structure has a body structure with an exterior surface and wherein said specified positioning indicia is on said exterior surface of said hand hold body structure; and d) whereby said climbing path is created by selecting from said climbing route setting assembly individual handhold structures for placement on said climbing wall from said plurality of handhold structures by matching said indicia from said map of said route setting guide to the corresponding positioning indicia on the exterior surface of each handhold to thereby identify a specific hand hold to create a climbing path on said climbing wall, placing each said hand hold onto said climbing wall at said predetermined hand hold mounting aperture corresponding to the x,y coordinates shown on said map and rotating each said hand hold on said climbing wall according to said indicia of said route setting guide to thereby create a climbing path on said climbing wall as selected from said map of said route setting guide.
