Research Article published by Journal of Hospitality Management and Tourism Vol. 8(2), February 2017This study aimed to assess constraints to the success of ecotourism network in Tanzania. Following an intensive survey and literature review, data were collected from members of Tanzania Association of Tour Operators (TATO) using a semi structured questionnaire and key informant interviews and then analyzed by Chi-square. The findings indicate that the success of ecotourism networks needs a strong regulatory framework, financial and infrastructural support. Explicitly, findings may urge the government to reduce taxes and license fees. Moreover, extra effort is required to ensure availability of direct international flights, all-weather and feeder roads; to avoid unnecessary long routes, trail cycle paths as well as encourage individuals, groups and society at large to open more cultural heritage centers. The study recommends for TATO, government and stakeholders to establish and maintain high quality infrastructure, widen financial access to support ecotourism and further studies on ecotourism networks.
