If you are visiting Lisbon during the month of June and are looking for something out of the ordinary to do, consider making a trip to see the International Equestrian Jumping Competition .  The contest has been held in Lisbon for 86 years and features horses and riders from as close as the next city and as far away as Brazil.  The competition, full of pomp and tradition, is held in Lisbon's Campo Grande Hippodrome each year during early June.   See the website for more details.
