The oldest and most venerated Field of Justice is known as Summoner's Rift. The Rift is located in a remote forest between Freljord, the Serpentine River, and the Ironspine Mountains. The Summoner’s Rift is one of a few locations in Valoran where magical energy is at its greatest concentration, making it a highly sought-after locale to pursue magical endeavors. Historically, the forest where the Rift resides was the site of several battles during Runeterra's various Rune Wars. In modern times, this battleground is known as the ultimate proving ground for any aspiring summoner. The Rift is also the battleground where some of Valoran's greatest political decisions have been made since the inception of the League of Legends.
The objective of Summoner's Rift is simple – destroy the enemy nexus. In order to do this, champions must traverse down one of three different paths (or lanes) in order to attack their enemy at their weakest points they can exploit. Both teams have their lanes defended by numerous turrets; each turret grows in strength the closer it gets to its respective nexus and each turret must be eliminated in order to gain access to the next turret in that lane. Cooperating with fellow summoners is an absolute requirement for success, as it is easy for a champion to find themselves ambushed by enemies in the lanes of the Rift.

It was also available during the 2010 Snowdown Showdown, replacing the Autumn version temporarily and made a return for the 2011 Snowdown Showdown in December 2011. The Winter Version of the Summoner's Rift has a few differences:
The Autumn Version of Summoner's Rift was a special variant designed for the 2010 Harrowing Seasonal Event. It replaced the Winter Version as the secondary version available and renamed Autumn Version after a poll on November 2010. It was temporarily replaced again with the Winter Version for the 2010 Snowdown Showdown. The Autumn Version uses music from the Twisted Treeline.
