You can get to Pamporovo ski resort from Plovdiv by public transport! Buses to Pamporovo depart from the Rodopi bus station in Plovdiv.
There are no buses from the airport to Pamporovo, so if you arrive in Plovdiv by plane, you first need to get to the bus station.
Since there is no regular bus service between the airport and the city, it is best to book a taxi in advance or take it at the airport.
Please note that from the Rodopi bus station, buses to Bansko run several times a day, you can check the schedule on the Avtogari.info website
In Pamporovo, the bus station is located in front of the Orpheus Hotel, almost in the center of the resort. From it you can get to any other hotel or apartment.
