Urban Trek USA's brochure shows it focuses on making the guests' sightseeing experience of San Francisco better than being aboard a tour bus and also to promote an environmentally friendly way of doing sightseeing.  Urban Trek USA accomplishes these things by making the Urban Treks a combination of a walking tour and using San Francisco's public transportation system, as well as providing good information about the sites. The Trek Leader is also less rigid with time limits when visiting the sites unlike most tours that only give guests a short time to take photos. The Trek Leader allows guests to spend as much time as they want on each site depending on the guests'  schedule. The brochure says, "Be a local San Franciscan for a day," and that is the experience guests get. Urban Trek USA's website is http://www.urbantrekusa.com/ and reservations can be made online or by calling (415) 265-8229. Best to call because special treks not on the website and brochure can be arranged during non-peak season.
