Information about tourism sites and attractions may be obtained from the following resources:

• Tourism commissions, ministries, or destination management organizations. In the Philippines, these includes Provincial/City/Municipal tourism Offices and the Department of Tourism (DOT) Regional Offices;
• Tour guide’s personal experience;
• Electronic sources, such as websites, social media, and online Videos officially uploaded by tourism establishments;
• Books, brochures, pamphlets, flyers, and travel guides;
• Familiarization trips;
• Interviews with locals; and
• Tourist themselves through their own stories, blogs, and feedback sheets.

We can classify the abovementioned sources of information into two: primary and secondary. Primary sources of information refer to those with first-hand experience of the destination. One way to gather information is by joining familiarization trips. School field trips are examples of this activity. Secondary sources often refer to reports and publications. Primary sources are usually preferred over secondary sources but they are not always available.

Technical data refer to specialized information that may be too difficult for non-industry practitioners to understand. An example is statistics that seems to make no sense if not explained in layman’s terms. Another example is the exact coordinates of a place, which are incomprehensible to people who cannot plot them in map.

It is important to triangulate information. Triangulation means cross-checking with other references to make sure that the information gathered is accurate and authentic.
