The Pokémon games have over 20 yearജs of storied history and have seen countless entries over those two decades. As such, with each new entry in the series, the games have been growing larger and larger over the years From Red and Blue to Sun and Moon, all of the games have huge maps that are riddled with optional and secret areas. While sometimes they're relatively boring or unnecessary areas, you can somet🍌imes also just find a surprise legendary kicking back! Or a dedicated area for a certain Pokémon that has 28 equally useless forms. E💫ither one.

If you’re just playing through a Pokémon game casually, there is a good chance that you’ll miss some of these areas. From post-game content to lore heavy secret areas and a literal alternate dimension, here are 25 hidden areas in Pokémon you might mis🍎s on a casual playthrough. Let us know in the comments if you’re finding out about any of these areas for the first time, or any areas we might h꧋ave missed. Enjoy!

25 Platinum: Villa

Do you remember that weird thing in Pokémon Platinum where you're just kind of given a house from someone that you move into and bought furniture for it that could barely interact with? Because that was the villa. I don't really know why this feature existed, but having all sorts of different NPCs visit and chat with you is a pretty neat feature. Minimum wage really sꩵtinks. Why can't I force animals to destroy each other and then be given a resort villa for it?

24 Sun And Moon: Battle Tree

The Battle Tree in Sun and Moon is completely avoidable, since it is post-game content, and it’s boriꦛng. It is𓆏 X and Y’s post-g🐼ame recycled. The only great thing about the unnecessarily large tree is that is houses old characters from the Pokémon series, such as Wally (okay), Blue (yes), Red (yesyes) and Cynthia (yesyesyesyes). This nostalgia driven feature is really the only interesting factor of the tree and♓ makes the visit worth it.

23 Black and White: Black City Or White Forest

Pokémon Black 1 and 2 and White 1 and 2 have arguably some of the largest version exclusives throughout the entire franchise, with the key difference being a version exclusive ꦐlocation. If you stuck with Black and Black 2, y🐻ou might never🐼 know that White Forest exists in White and White 2. The rev🔯erse is the same for Black City. This is a version difference that I would love to see come back in future installments.

22 🌠 X and Y: Battle Ma▨ison

In X and Y, there was this weird castle where you could go and battle like▨, a royal family of some sort?

I don’t really know. It was weird.

Essentially, for every trainer that you beat in the Maison, you can rౠank up, before becoming the Grౠand Duke or Duchess. After you complete the storyline of the games, gym leaders, the elite 4 and Diantha appear as different nobles, with Diantha having level 80 Pokémon under certain conditions, the highest in the game. It’s a shame she still kind of stinks even then.

21 Emerald: Battle Frontier

A complete overhaul from the Ruby and Sapphire Battle Tower, the Battle Frontier is one of the most expansive post-game areas ever, featuring seven different bat▨tle facilities. Each of the facilities offers a different type of battle experience, including one where Pokémon battle without any input from their trainers! While this area was a bla🐽st to play through, Omega Ruby and Alpha Sapphire actual🍎ly opted to remove the area entirely. You know, because they’re terrible games.

20 Red And Blue: Kanto Power Plant

The Power Plant is never an area you need to go to in any of the 487 Kanto games that we currently have available, but it is always a worthwhile experience. That’s because it always holds Zapdos, one of Kanto’s legendary birds.♔ Besides that, the Power Plant also features other inteಞresting Pokémon such as Electabuzz.

Also Muk for some reason. He’s there too.

Also a bunch of Electrodes pretending to be items, 🧸which… please don’t do tha🥀t.

19 Diamond and Pearl: Turnback Cave

In Pokémon Diamond and Pearl, Turnback Cave was the home of the legendary Giratina, before becom♌ing the mascot legendary of Platinum. The cave ꦇworks as a maze, where each room you enter is picked randomly. If you can’t find Giratina before 30 rooms, you have to try again. The cave also features a selection of ghost Pokémon and an entrance to the Distortion World.

And the icon Chingling!

He’s welcomed anywhere in my book.

18 HeartGold And SoulSilver: Sinjoh Ruins

Situated between the Johto and Sinnoh regions, we have the Sinjoh Ruins🐭.👍 This event location for HeartGold and SoulSilver allows the player to 💯get a Palkia, Dialga, or Arceus to add to their party. However, the absolute best part of this event is the lore that comes with it. I won't spoil it, but there's a whole heck of a lot of it that makes this event great. Ok I will spoil one little⭕ bit, Cynthia is there, so you know that it has to be great.

17 X And Y:  Terminus Cave

While we had to wait until Pokémon Z for Zygar🌞de to have a starring role (lol jk), the legendary was capturable in the X and Y optional area, Terminus Cave. This Pokémon raised 🧸many questions during the X and Y era, even with its capture being completely optional and missabl🍌e. Sadly, we never got it 🐭as a mascot Pokémon and had to wait until Sun and Moon for more info on the mysterious legendary.

16 FireRed and LeafGreen: Sevii Islands

Only ever appearing in FireRed and LeafGreen, the Sevi𝕴i Islands of Kanto serve as post-game content for the titles.

Each of the island🍰s is𓄧 diverse, and all feature their own side mission.

This type of post-game content is one of the best types, as it features all sorts of fun stories, lore, and Pokémon that are unobtainable in th🎐e rest of the game. Also, there are nine Sevii islands so thꦡat’s just confusing.
