Magtheridon's Lair is one of three Raids available during Phase 1 of Classic The Burning Crusade, and one of two available without any attunement quest required.
Magtheridon's Lair can be found at the bottom of Hellfire Ramparts located in Hellfire Peninsula.
For players with a flying mount, it is simple enough to just fly straight down, but if you do not have a flying mount, you will need to travel slightly west and make your way down the Ravine.
There is also a summoning stone located outside the instance portal, and Warlock players can summon you to the instance.
