Salem by Cell presented by Hocus Pocus Tours
There are times when you want to tour a city with a group, and other times where you'd prefer to see the sights on your own schedule. Hocus Pocus Tours accommodates the latter group with its signature self-guided cell-phone-based tour, Salem by Cell. Users forego the long lines and crowds common with group tours and have a wicked good time accessing the tour's 80 minutes of city history at any time of day and can customize the order of their tour stops, with as many meal breaks as they'd like to pop into an intriguing shop or grab a meal at a local restaurant. The tour covers 45 stops, including sites involved in the city's witch hunt and important local architecture.
