Aerodactyl’s Mega Stone Aerodactylite can be found on the highest floor of Meteor Falls. This is a cave west of Fallarbor Town.
You need HM05 Waterfall to reach the Mega Stone’s location. So make sure you’ve already defeated the eighth Gym Leader to obtain the HM for Waterfall. You’ll also need a Pokémon that knows HM03 Surf to traverse the cave.
Aerodactylite Location (Step-by-Step)
Most Mega Stones, including Aerodactyl’s Mega Stone, are only obtainable after you defeat/catch Kyogre or Groudon in Sootopolis City; more specifically, in the Cave of Origin.
This major event happens right before you’re able to challenge the eighth and final Gym Leader.
After you finish those events, the Aerodactylite can be found inside Meteor Falls, which is a large cave with a massive waterfall located west of Fallarbor Town.
While you can visit Meteor Falls early in the game, you will need to climb the waterfall inside to fully explore it. To obtain the Aerodactylite, you’re going to need the following:
- The eighth Gym Badge from Wallace, the Gym Leader from Sootopolis City
- A Pokémon that knows HM03 Surf
- A Pokémon that knows HM05 Waterfall
Tip: Bring a Pokémon with Dig or an Escape Rope to escape immediately after getting your Mega Stone.
If you’re all set, fly to Meteor Falls to get started.
Step 1: Enter the cave, and once you’re inside immediately head west.
Step 2: Head down the stairs and use Surf on the body of water directly in front of the waterfalls.
Step 3: Use Waterfall to climb up the large waterfall in front of you (you’ll be facing the northern side of the cave).
Step 4: Keep surfing north, then land on the patch of land you bump into. Go through the cave entrance on the north wall here.
Step 5: Once you’re in the next room start walking right.
At the end of this path you’ll come to a ladder – go down this ladder once you reach it.
Step 6: In the next room, follow the path heading left, then turn north past the Dragon Tamer.
Step 7: Climb up the ladder at the very end of the path.
Step 8: In the next room, head right past the Old Couple, then turn to start going north up some steps.
Step 9: Go up all of the stairs, and then go down six ledges. Make sure you only go down 6 ledges in total, or you’ll miss the mega stone.
Step 10: Interact with the sparkling item located directly before the seventh ledge (you’ll find it in the very lower-right corner). This is your Aerodactylite.
How Aerodactylite Works
Mega Stones like the Aerodactylite are held items that allow certain Pokémon to Mega Evolve, granting them a massive boost to their base stats.
Most Mega Evolutions also change the Pokémon’s ability, which lasts until the battle concludes.
When Aerodactyl Mega Evolves into Mega Aerodactyl, it changes its ability to Tough Claws, which powers up moves that make direct contact by 30%.
Mega Aerodactyl is a great sweeper thanks to its high offensive stats, decent bulk, and expansive movepool. You can also set up with Hone Claws to make Mega Aerodactyl a potent wallbreaker.
Its versatility makes it very easy to fit on any competitive team.
