Farm workers are a vulnerable working population that face significant inequalities in accessing health services, including those for HIV prevention, treatment, and care. This descriptive phenomenological study aimed to explore farm workers' experiences when accessing HIV services, and was conducted in Limpopo province, South Africa. Eighteen in-depth interviews (IDIs) were conducted in four health facilities from two districts, and two focus group discussions (FDGs) were conducted in one of the farms within the province. Purposive and systematic random sampling were used to select study participants. A deductive thematic approach was used to analyze data, informed by the social-ecological model of health. The results reveal that farm workers perceive multiple interdependent factors that inhibit or enable their access to HIV healthcare services. Key barriers to HIV healthcare were transport affordability, health worker attitudes, stigma and discrimination, models of HIV healthcare delivery, geographic location of health facilities, and difficult working conditions. Key facilitators to HIV healthcare included the availability of mobile health services, the presence of community health workers, and a supportive work environment. The findings suggest disparities in farm workers' access to HIV services, with work being the main determinant of access. We, therefore, recommend a review of HIV policies and programs for the agricultural sector, and models of HIV healthcare delivery that address the unique needs of farm workers.
