The study aims to present a GIS-based assessment of the transport accessibility of the material anthropogenic tourist resources (historical, architectural, religious, and cultural-institutional) in the city of Sofia, Bulgaria. The method used in the study in order to achieve the objective is measuring the walking distance with the use of the ORC tool in QGIS. A vector point layer of all public transport stops was initially added, where the points (bus/tram/trolley stops) served as a starting point for walking distance measurement. The analysis of the pedestrian and transport accessibility to the anthropogenic tourist resources in Sofia Municipality has been conducted using data from the Ministry of Tourism’s National Tourism Register, the Integrated Development Plan of Sofia Municipality 2021-2027, and the National Statistical Institute. The results show that the vast majority of the studied sites are concentrated in the historical and modern center of the city, which facilitates their accessibility by public transport. However, most of the sites fall within the hourly -paid, so-called Blue and Green parking zones, which hampers the accessibility by own vehicles, thus signifying the public transport importance for easy access to the tourist sites in discussion. Of the 50 sites examined, only 5 fall in neither the Blue, nor the Green Zone. The situation is further complicated by two services that additionally reduce the number of parking spaces for both city residents and visitors: 1) official subscription and 2) residential parking. Of the 50 sites studied, less than half (23) are suitable for people with disabilities. The analysis of the existing accessibility to cultural and historical sites is the basis for alternative proposals for accessibility improvement. In conclusion, the effect of tourist sites’ accessibility on the development of tourism in Sofia Municipality has been determined.
