Idyll Beach is an Unexplored Territory in Xenoblade Chronicles X. It is a very small beach located at the FN Site 223 in Noctilum. It can be found by swimming along the eastern side of the northern island of Noctilum. Like all Unexplored Territories, its discovery yields an achievement ("The Heavenly Idyll Beach"). Unlike most other areas outwith New Los Angeles the Idyll Beach shows signs of Human activity already, as a pair of deck chairs and beach umbrella have been set up. There are no enemies here.
