Farin Ruwa in Nasarawa State is one of the highest waterfalls on the continent, with a drop of more than 150 metres (Victoria Falls' drop is a mere 108 metres). And yet, according to this article, there has been just over 1,000 visitors since 1999. The people I know who have been there all say its a stunning experience. The falls are only three hours drive from Abuja. Plans to develop tourism to the site and also for a hydro-electric power project have yet to be implemented. A trip during this damina season is in order methinks.
