The primary goal of tourism policy is to promote sustainable tourism, which means balancing the economic, social, and environmental impacts of tourism in order to ensure that it is a long-term benefit to the destination.

The three main pillars of sustainable tourism are economic viability, social equity, and environmental protection. Economic viability ensures that tourism generates sufficient revenue to support the local economy, social equity ensures that the benefits of tourism are shared equitably among all stakeholders, and environmental protection ensures that tourism does not damage the natural environment.
