Answer:
Interactive maps and music videos trailers.
Step-by-step explanation:
Without a doubt, one of the main options is Photography. However, with the technological advances of the last decade, the creation of an interactive map showing the costs, places of entry to the park (requirements), delivery time, restrictions (Is it possible to camp? Is it possible to entry of pets ?, etc), the fauna and flora found within the park, possible sightings, the best times of the year to visit the park, and internal routes - with its travel time - would be an interesting option. In addition, if the objective is to promote the park, a trailer with videos made from drones and a musical background that inspires, could attract tourists in a mass way.
