There are plenty of private buses that go daily from Mumbai to Goa, and are available in various categories such as AC, Volvo, Sleeper, or Seater.
However there are no Mumbai to Goa government buses that I could locate, that go directly from Mumbai to Goa.
If instead of private buses, we want to explore the option of going by Maharashtra state Government buses from Mumbai to Goa, then we can look at government bus options that can take us along the NH17 Mumbai-Goa highway, at a place nearest to Goa such as Kudal or Vengurla, from where we can explore further options to reach Goa.
However going by private buses, or by trains, or by flight are the preferred, direct and more convenient options.
