There have only been a few Disney collectors pins based on the Discovery Riverboats. This is largely due to a very short attraction life of ~ 1 1/2 years (1998-1999) and the fact that the ride no longer existed by the time Walt Disney World started producing the modern series of collectors pins as part of the Millennium Celebration of 2000.
Asia’s Boat Dock
There were two boat docks as part of the Discovery Riverboats attraction, Safari Village and Upcountry Landing. Upcountry Landing was located in Asia, just past the bridge from Safari Village. Asia itself had minimal attractions at park opening in 1998 as the bulk of the land was still under construction. In fact, Flights of Wonder and Discovery Riverboats were the only attractions for Asia at that time.
