There is only one copy of TM23 Iron Tail in the game, and you’ll find it on Iron Island. Note that you can only get to Iron Island by taking a ship from Canalave City.
As for what this TM move does:
Iron Tail is a damage-dealing Steel-type physical move that also has a 30% chance of lowering the target’s Defense stat by one stage. The move has a high base power, but low accuracy.
TM23 Iron Tail Location (Step-by-Step)
TM23 Iron Tail is found on Iron Island, which lies far north of Canalave City and requires taking a ship to reach it.
Iron Island is full of Rock- and Steel-type Pokémon of levels mostly in the low-30s. So keep this in mind when prepping your party before heading out.
To locate Canalave City’s harbor, first cross the drawbridge to the west of the Canalave Pokémon Center.
Once you pass the Canalave Gym, turn south.
Pass the houses going down, and then turn right after you pass Sailor Eldritch’s house.
Speak with Sailor Eldritch at the dock and he will offer to take you to Iron Island.
Once you arrive on Iron Island, head up the staircase to the east.
Pass the blue-roofed house here and take the northern staircase further up the mountain.
Head through the entrance to Iron Island’s cave at the top of the staircase.
Once you’re inside, descend the right-hand staircase.
Then move down a bit and climb the first set of stairs you see that lead up to an elevated rocky platform.
From the top of that platform, head eastward.
Head east until you reach a lone red oil drum, and then climb down the nearby staircase and head south.
Make your way around the Picnicker trainer and climb up the stairs just south of her location.
From there you’ll be able to wrap around a small path & step onto a lift that will lower you down to the next floor.
Once you’re down on the lower floor, step off the lift and descend the staircase to the east.
From this floor, wind your way across the path to the direct south, taking two tiny staircases up & down – you’ll also pass a Worker trainer NPC.
Right after you pass the Worker and go down that small staircase, there will be a Poké Ball item on the ground beside a single red oil drum.
Pick up this item to get TM23 Iron Tail. Note that this is the only copy of TM23 in the game.
Iron Tail Details and Uses
Iron Tail is a damage-dealing Steel-type physical move that has a high base power but low accuracy. It also has a 30% chance of lowering the target’s Defense stat by one stage.

|PP||15 (max. 24)|
This is yet another move in a long line of moves with impressive power and disappointing accuracy.
A 75% percent accuracy all but guarantees at least one out of four uses of this move will fail – but sometimes it fails much more often.
Plenty of trainers have been left squirming in agony after these kinds of moves failed three or even more times in a row. There is no doubt it can be useful, especially backed by Steel-type STAB damage, but it is highly unreliable.
Iron Tail vs. Iron Head
There is some debate about whether Iron Tail or Iron Head is the better Steel-type move.
Iron Tail has more raw power than Iron Head, sure.
But not only does Iron Head have a 100% accuracy stat, it arguably has a better secondary effect: a 30% chance of making the target flinch with every attack.
A one-in-three chance of preventing your opponent from acting is much more effective than a one-in-three chance of slightly lowering one of its stats. And lowered stats can be easily cured simply by switching the Pokémon out of battle.
Aside from that, Iron Head’s 80 base power isn’t bad, and Iron Tail’s 100 base power isn’t high enough to justify the cut in accuracy.
So Iron Head is generally the better move.
But one of Iron Tail’s upsides is that a vast number of Pokémon of all types can learn it.
So it can be used to expand type coverage to Pokémon who shouldn’t have any business learning Steel-type moves (notably, Ash’s Pikachu learns Iron Tail in the anime).
