Disclosed are various embodiments for a climbing apparatus for pet training and exercise. The climbing apparatus for exercising or training pets may include, for example, a first ramp directly coupled to a second ramp at a coupling point located at a peak of a hill, the first ramp and the second ramp having an angle of incline that is substantially similar, thereby forming a substantially symmetrical and triangular structure. The first ramp and the second ramp can include supports projecting from a surface of the first ramp and the second ramp to facilitate navigation of a path that comprises an incline of the first ramp and a decline of the second ramp. In addition, the supports can render the apparatus free-standing and portable.
