The Reef

The Reef is a multiplayer stage in Splatoon 2.

The Reef is located a few blocks from Inkopolis Square, it's a popular area to hang out when it's not being used for Turf War. The Reef is home to some of the most popular boutique shops in the city.

Layout
The Reef features many wide open areas, with separate high and low levels. This creates many flanking paths around many of its key areas. The base is not accessable to the enemy team and includes a path which allows easy access to the far left and far right side of the map. Dropping from the base is a small square raised area that leads into the meat of the map. Notably there is a stone bridge at the center of the map which acts as a straight path into the enemy area. The map also boasts a large grass lot below the bridge, with a tree and a block as obstacles. The area underneath the bridge indents downwards and the turf is inkable.

Ranked Battle Terrain
In Ranked Battle, specifications for the terrain or placement of objects are different between the modes; these changes create new paths or new objects to take cover behind.

Splat Zones
In Splat Zones, the zone can be found below the bridge. Boxes have been added around the bridge to help teams attack players on the bridge and gain control of it and the zone.

Tower Control
The tower initially starts below the bridge. When advancing, the tower goes left and retreat back to your side, going around the tree before advance back towards the enemy base. It will travel up the ramp and up into the small square lot in front of the enemy base where it will reach its goal.

Checkpoints:
 * The first checkpoint is located just left of the tower's positon.
 * The second checkpoint is located next to a tree when it retreats back towards your side.
 * The third checkpoint is located after it starts heading back towards the enemy base just before the homestretch, still in the grass lot.

Rainmaker
Like the tower in Tower Control, the Rainmaker starts below the bridge in the center of The Reef. Each goal is located next to the car in each base. Several ramps have been added that give each team access to the other team's base.

Clam Blitz
The basket is located below the unaccessable area of the base and there isn't any bump near it. There is a new block in the right side of the bridge to get above the wall.

Pre-release version
This Pre-release version of The Reef was playable in the Switch Event Nintendo raised and changed to the release version in the Splatoon 2 Global Testfire. The pre-release version included many differences, such as:
 * Much more flat surface at the center of the stage.
 * Wooden bridge instead of raised grate bridge with a wooden box in the center.
 * Pots instead of bumpers in each side's platforms.
 * Lower Spawn Point platforms.
 * Two trees in each side of the center instead of one.

Release 2017 version (until version 4.1.0)
The Reef was released with launch of Splatoon 2.

Octo Canyon
Mission nine of Octo Canyon, Octoling Strike, takes place on a modified layout of the release version of The Reef. This layout remained the same after the release of the updated version in 4.2.0 update.

November 2018 updated version (from version 4.2.0)
On 2018-10-31, an announcement was posted on the official Splatoon Japanese Twitter account stating that from 2018-11-01 until the release of Version on 2018-11-07, The Reef will be "closed for renovations", similar to the announcement made for Starfish Mainstage in Version. The announcement includes a blueprint of the stage with the planned changes scribbled on it. Changes include:
 * Areas around the teams' spawn points were deepened and widened, which will allow easier recovery from spawn camping.
 * More passages added from the spawn points to the flank areas.
 * The buildings surrounding the central area were moved back, making it larger.
 * In Ranked modes:
 * Splat Zones: Increasing the number of splat zones from one to two.
 * Tower Control: Very small modification to the path of the tower.
 * Rainmaker: Moved the Rainmaker's location from below the bridge to on it.
 * Clam Blitz: Moved the basket to the side and added a bump.

Trivia

 * The internal codename for this stage in the game files is "Ditch".
 * The updated version of The Reef from Version also changed the fashion posters displayed on the stage, now featuring Octolings and Inklings with new clothing, appearing on a black background with red text spelling what seems to resemble "17XX" as seen here. Previous versions of The Reef had posters of Inklings with different clothing and a white background as seen here.

Etymology
A reef is a habitat for animals and land-dwelling organisms, popular area that attracts a diverse assemblage of organisms, especially algae, and fish. In Splatoon 2, The Reef is a popular area for Inklings to hang out when it's not being used for Turf War and home to some of the most popular boutique shops in the city.
