Soundwalk is an award-winning audio tour “for people who don’t normally take audio tours”. They require you to immerse yourself in a city and give yourself over to an experience that takes you into private spaces and is guaranteed to get your adrenalin flowing. MP3 tours are available for various areas of NYC – Bronx, Brooklyn and Manhattan, as well as Paris, France; Varanasi, India; Beijing, China and Ibiza, Spain.
The tours started out as CDs but Soundwalk have recently upgraded their website which looks gorgeous, provides overviews and maps and gives audio an video previews of the tours.
