Visitors to heritage sites want to engage with a destination through learning, interacting and doing, rather than simply observing.
Authenticity is very important. Visitors particularly value cultural aspects that are supported by the local population.
Accessing events enjoyed by local people and which connect to a local area is integral. This could include:
eating local food
participating in festivals or arts performances
visiting atmospheric towns and villages
discovering links with famous people or other aspects of contemporary culture (e.g. locations of movies etc.).
