San Gil, 96 km from Bucaramanga, you can discover other extreme sports. Rafting is one of its most popular activities here with experienced guides offering several trips on the rivers. The excursions which take place on either the Fonce or Suarez river offer adventurers differing levels of difficulty, making use of rafts, kayaks or hydrospeed - a form of river bodyboarding. http://www.southamerica.cl/colombia-guide/bucaramanga.htm
