Was traveling from Cetinje trough Reka Crnojevica direction Virpazar today. The crossings are not apropriate signed. (the sign "gastronomic route" at many crossings is for somebody who is hungry good but not for traveler. To avoid missing your route get a good map or gps. We enjoyed the trip anyway, but was sad because I miss the route to Virpazar and came to Podgorica instead. The landscape spots were magnificant anyway.
But this is in many places and towns in Montenegro so. The domestic people know where the places are, and the tourist should find out.
If you are by car just follow the signs on the main road Budva-Podgorica. There is also a bus line from Podgorica but not often. The other way to get there is to take bus that goes to Podgorica. Ask the driver to stop at the turning to Rijeka Crnojevica and than stop some car that goes there. It shouldn't be long until someone pick you up :-)
