You can't just go to one location and arrive at the constellation because the constellation is made up of stars at different locations and different distances. The nearest main star in the constellation is at a distance of 48.72 light years and the furthest main star is a distance of 317.90 light years. The average distance to the main stars is 150.56 light years.
The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
The nearest star to Earth is HIP 62951 which is roughly about 24.55 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HD 104067 which is about 68.71 Light Years.
The furthest star that is located in the constellation is HIP 63067 and it is 29651.21 light years away from the Sun.
The brightest star in Corvus is Gienah Ghurab and is located about 69.24 light years from the Sun. The star has a apparent magnitude of 2.58 but an absolute magnitude of -0.79 when the star is viewed from a distance of 10 Parsecs or 32.6 Light Years. The star is only recognised as being Gamma Corvi rather than having Alpha status.
The dimmest star that can be seen in Corvus with the naked eye is HD 109931. The dim star has an apparent magnitude of 6. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan.
LHS-2520 is a small insignificant star in the constellation but what does make it special is that it is the home of Krypton, the home planet of Clark Kent aka Superman. It was chosen by Neil deGrasse Tyson, the American Astronomer Personality and Frederick P. Rose Director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City. D.C. Comic asked Neil deGrasse Tyson to chose a star that Krypton could orbit and he chose this star.
Corvus was chosen as the constellation because the Smallville Crows are the American Football team for the town. LHS-2520 was chosen because it matched the criteria that Neil set for such a star. LHS-2520 has not gone supernova though. Its not known if there are any exoplanets in orbit round the star.
Corvus was the crow of Apollo. Apollo wanted fresh water for a sacrifice to Zeus but the crow did not return in time. Corvus used a Crater to fetch the water in. The crow stopped to wait for some figs to ripen before he could eat. Corvus, fearing for his life, made up an alibi story with Hydra but Apollo didn't accept it. Corvus was punished that his throat would become sore when figs were ripening. It was turned to black from white as punishment and a warning to others. It was placed in the sky.
