What does the app offer?
First, the app lists all the important information for your visit: hours, prices, directions, accessibility, visitor information, dining, and contacts. There are three different adventure tours available to download, ready for you to use offline on site. You can listen to the tours using headphones or by holding your smartphone to your ear, the way you would for a phone call. It’s best to download the app while you’re still at home and to take a peek at the monument. That way, you can start your visit as soon as you arrive on site.
