Although Dar es Salaam City is endowed with numerous cultural heritage resources, it fails to exploit such potentials. While there were some initiatives to boost cultural heritage tourism in the city, their efficacy was unknown and they remain undocumented. This study was designed to assess public awareness means and their effectiveness in promoting cultural heritage tourism in Dar es Salaam City. Data collection was through questionnaires, focus group discussions, observations, and key informant interviews. Findings indicated that most of the existing potential sites were not known as cultural heritage tourism sites such that they were regarded like any other normal places in the city. Available public awareness strategies (except a few) were ineffective and inaccessible. One could then wonder how available cultural heritage assets may be made known and attract others to take part. The study calls for public awareness strategies to improve knowledge on available cultural heritage assets to the general public, a measure, which will positively enhance accessibility to cultural heritage assets, improve goodwill as well as cooperation to tourists and improve ethics of their care. Such undertakings eventually will lead to sustainable cultural heritage tourism growth.
