Cadw operates most of the heritage sites in its care and opens them to the public. In 2010–11 there were an estimated two million visits to Cadw properties. In some cases, these are major tourist attractions and offer tours of the monuments, exhibitions and display panels. Cadw also produces books and guidebooks on many of their properties. Many of the sites are unstaffed, free to access and have interpretation boards to explain their significance.<ref name=Introduction/> Alongside this, a mobile app was released in 2016, which provides basic information for visitors as well as an interpretative aspect for larger sites.<ref>{{cite journal|doi=10.11141/ia.44.15 | issue=44 | title=Review of Cadw Mobile App [application] | year=2017 | journal=Internet Archaeology | last1 = Rothenberg | first1 = Miriam | doi-access=free }}</ref>

The five most frequently visited properties in 2010–11 were [[Caernarfon Castle]] (192,695 visits), [[Conwy Castle]] (190,031 visits), [[Caerphilly Castle]] (94,707 visits), [[Harlech Castle]] (93,242 visits) and [[Beaumaris Castle]] (80,660 visits).<ref name=report2012/>

To provide a better context for the history of Wales, in 2010–11 Cadw was developing thematic 'All Wales Interpretation Plans', that could develop themes across numerous sites and localities. There were eight themes:-
* Origins and prehistory.
* Roman invasion and settlement.
* Celtic saints and pilgrimage.
* Churches, chapels and monastic landscapes.
* Castles and Princes of Medieval Wales.
* Artistic responses to the landscape.
* The Defence of the Realm – Pembrokeshire.
* Wales – the first industrial nation.<ref name=report2012/>
