Walking tours led by an AR avatar guide. 130+ GPS (and remote) tours in 80+ cities created by amazing guides and MA/PhD level experts. Our tours will give our users the feeling of being with a real life tour guide. Sherpa uses both GPS and AR, it uses a significant amount of battery power. We suggest using the audio-only mode during most of the tour narrations. Make sure your battery is fully powered when you start and for Extended Edition tours you might want to bring a portable battery charger. Click HERE to visit Sherpa Tour website.
