The Friend Safari (Japanese: フレンドサファリFriend Safari) is a facility in Kiloude City where Trainers can catch Pokémon that cannot normally be found in their journeys.

Once the player has entered the Hall of Fame, they are able to access Kiloude City and thus the Friend Safari. At the Friend Safari, the player is able to access Safaris for any Friends that are successfully registered in the 3DS's friend list (regardless of whether or not that person has played Pokémon X and Y). Each Safari has designated Pokémon that can be encountered, all belonging to a designated type; these are determined by the Friend's friend code and will not change. As such, any players who successfully register a given friend code in their 3DS will all be able to access the exact same Friend Safari. There is no way for the player to access the Friend Safari for their own 3DS.
Friends who have been recognized in the PSS will usually be represented in the Friend Safari list by the avatar they were last seen with on the PSS, while Friends who have not been seen will be represented by a "?" icon. However, if the player has added more than 100 Friends (by deleting some at some point), the earliest-seen avatars may begin to be forgotten and revert to "?" icons until they are next seen on the PSS; this does not affect the rest of the Safari's status, however. Also, if a Friend is deleted from the 3DS's friend list and then readded later, their Safari may retain the status it had before it was deleted.
All Friend Safaris have three Pokémon that may be captured. Only Pokémon from the first two "slots" are available until the Friend to whom that Safari belongs enters the Hall of Fame and subsequently appears online in the PSS at the same time as the player (thereby also allowing the PSS to recognize the Friend if it had not already). Once all three "slots" are unlocked the Pokémon encountered in that Friend's Safari will thereafter have a chance of having their Hidden Ability.
Pokémon encountered in the Friend Safari are guaranteed to have at least two IVs of 31 and have a higher chance of being Shiny. When checking for Shininess, the game generates up to four extra personality values to attempt to find a Shiny value, resulting in a rate of 5/4096; this effect can stack with the Shiny Charm, which results in a rate of 7/4096.
All Pokémon that appear in the Friend Safari are level 30 (causing some, such as Muk and Drapion, to be underleveled). Pokémon can be found in the Friend Safari regardless of being game-exclusive Pokémon or otherwise unobtainable in either version.
In the tables below, note that "rate" does not refer to encounter rate but rather the likelihood for a Pokémon to have been selected for that "slot" of a Friend Safari. All Pokémon that can appear in a given Friend's Safari have the same encounter rate.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
Initially, Vivillon's icon would not replace the Poké Ball icon after it was encountered. This was fixed in the version 1.3 patch.
Floette is the only Pokémon to have a greater than 50% chance of appearing in a Friend Safari.
Cascoon is the only Pokémon to be found in a Friend Safari who does not match the designated type, as it is a pure Bug-type Pokémon found in a Poison-type Friend Safari. Its evolution, Dustox, however, is part Poison-type.
