In this paper, we consider a (2+1) D black hole conformally coupled to a massless

scalar. Then the geodesic motion of test particles and light rays in the vicinity of the spacetime of

this black hole is studied. Moreover, the geodesic equations are solved analytically according to

Weierstrass elliptic and derivatives of Kleinian sigma hyperelliptic functions. Also, the possible

orbits are discussed and classifi ed according to the particle's energy and angular momentum.
