Located on one of the tallest flat-topped mountains in the Ranges, the Pokemon League of Hojanne is all you would expect of it: Massive arenas and stadiums, Towering buildings, a lush Trainer's Village and everything else you would usually see at a place which regularly held large scale tournaments.
Aside from the Annual Elimination Tourney, the League holds all sorts of smaller events from races to miniature battles in a confined space all year round, so it does not hurt to drop in from time to time.
