Fairies have been a common feature in Zelda games for decades, and while The Legend of Zelda: Breath of the Wild breaks from convention in so many ways, it retains this key element.
You'll find four Great Fairies in the game, each residing its own foundation hidden in Hyrule. You'll want to seek them out as soon as possible as they help you upgrade your armour using crafting materials obtained during your quest. The catch? You'll have to give each one a number of Rupees to unlock these upgrades. Each upgrade costs more than the last, starting with 100 and then moving up to 500, 1,000, and eventually a whopping 10,000 rupees for the final fairy.
So where are these fairies hiding? That's what we're here to help you with.
Cotera Fairy Fountain Location
This fountain is northeast of Kakariko Village in the Necluda region, making it one of the first ones you're likely to discover. Locate Pikango in Kakriko Village (he's stood outside Impa's house) and you'll unlock a quest entitled "Find the Fairy Fountain." You'll need to take a snap to show Pikango, so make sure you've enabled that feature on your Sheikah Slate by visiting the Hateno Ancient Tech Lab first.
Kaysa Fairy Fountain Location
This fairy is hiding in the Tabantha Region, south of the Rito Village. Get to the top of the Tabantha Tower on Nero Hill and look south, you should be able to spot the telltale flower bud below on a ridge. It's within gliding distance so is quite easy to reach from the tower. Visit the Tabantha Bridge Stable and speak to Toren beforehand for an optional side quest which will give you the 500 Rupees to offer to Kaysa, saving you a spot of cash.
Mija Fairy Fountain Location
This fairy is found in Akkala Region, sound of Lake Akkala. The nearest landmark is Dah Hesho Shrine. Look for a circle of coloured trees - the fountain is in the middle.
Tera Fairy Fountain Location
Make for the Southwestern tip of the Gerudo Desert and keep your eyes peeled for a large dragon skeleton, under which you'll find Tera's Fairy Fountain and the Hawa Koth Shrine. You'll need some kind of protection against the heat and a Sand Seal is almost essential.
