This study is devoted to explore the physical aspects of dark matter on wormhole geometry with the galactic halo regime in the gravity. To complete this analysis, we consider the diagonal tetrad for gravity and explore the field equations for Morris and Thorne metric in the Schwarzschild coordinates. The crucial aspect of the present investigation is the implication of dark matter to find traversable wormhole solutions in galactic halos. Implementation of the dark matter halos turns out to be very interesting as this corresponds to the new wormhole solutions in the framework of gravity, which is recently ignited by the natural prediction of late-time stages and early stages of the accelerated expansion of our Universe. We provide a detailed analysis supported by four different profiles of dark matter halos. We solve the filed equations of the gravity and find exact solutions for wormholes that are immersed in the galactic halo. Further, we use the obtained shape functions for the galactic halo wormhole to analyze the energy conditions and discuss the presence of exotic matter. We observe that our obtained solutions for four different density profiles of dark matter halos are viable.
