The Large High Altitude Air Shower Observatory (LHAASO) has observed tens of gamma-ray sources with significant emission above 100 TeV. These gamma-ray sources are probably the Galactic accelerators of PeV cosmic-rays. Thus, high energy neutrinos above 100 TeV are expected to be observed from these PeVatron candidates. We propose the Huge Underwater high-energy Neutrino Telescope (HUNT) with instrumented volume up to 30 ${\rm km^{3}}$ to search for neutrino sources above 100 TeV, which will help us to identify the PeVatrons in our Galaxy and understand the acceleration of PeV cosmic-rays in the deep universe. Here, we present some preliminary results of the telescope simulation, the performance evaluation and the pathfinder experiment.
