Splash Highway is a medium-difficulty track based in the City, and contains multiple split pathways and Grind Rail sections. As its name would imply, several segments take place above water, and the end is even very slightly below the water's surface.
In Splash Highway, the playable characters are stuck running down the level's road and can only move left and right between the road's four lanes (akin to the Quick Step). While running, the player can pick up powerups from Item Boxes and utilize the gimmicks native to this track.
Splash Highway has many environmental obstacles which the player can either jump over, roll under or move around. Running into one of these obstacles will result in the player taking damage and lose some of their Rings. Falling into bottomless pits on the other hand forces the player to restart from an earlier point on the track.
The racers begin on a long stretch of ground, before entering a section with several obstacles placed in their path. The track soon splits, with the lower side on the left providing a series of four Dash Panels, while the upper side on the right has only two Dash Panels, but also Rings and Item Boxes. From there, the racers will continue running through an area with several obstacles before coming to a set of several hurdles. Beyond this is a short set of Grind Rails, and a slightly longer stretch of land leading to a long set of Grind Rails. The rest of the track alternates between land and grind rails leading up to a long section with pillars and Dash Pads set before the finish line.
