Palmetto Trail. The Palmetto Trail is a planned 425-mile-long (684 km) foot and mountain bike trail in South Carolina for recreational hiking and biking. Several of the sections are also equestrian trails. It will extend from the Oconee County mountains to the Intracoastal Waterway in Charleston County.
An Abbreviated Freedom Trail. The Freedom Trail is a 2.5-mile stretch hosting 16 sites pertaining to the Revolutionary War. You could take a costumed guided tour or, more appealingly, download a map and follow your own itinerary. If you have limited time, concentrate on those sites in and immediately around the North End, which is also Boston's Little Italy.
