Shelltop Sanctuary

Shelltop Sanctuary is a golf course added in version 4.0.0 of Mario Golf: Super Rush. It takes place on top of a grassy plateau above the clouds with numerous shell-shaped structures and statues of the Koopa Troopa masters from Golf Adventure found throughout. In the center of the course is a pond inhabited by Cheep Cheeps and Cheep Chomps, the former of which periodically jump over the bridges, serving as obstacles for the players during Speed Golf. Certain areas of the course have fans which blow away balls that get caught in their wind stream. Like New Donk City, Shelltop Sanctuary is an all par 3 course with two available layouts. Unlike New Donk City, the locations of the tee boxes and greens are the same for both layouts, with the difference between the two being which greens are traveled to from which tee box. The tee boxes are colored blue in the Amateur layout and yellow in the Pro layout. This is the only course other than All-Star Summit to have Star Coins, which completely fill the Special Shot gauge when collected.

There is also a third layout, Special, which is exclusive to the One On, One Putt challenge. It is unlocked by clearing the Pro layout's challenge. For this layout, the player is only given one or two preselected clubs and a putter for each hole, including custom clubs otherwise only usable in Golf Adventure that dramatically alter the ball's trajectory, though Special Shots can be used to negate these effects. The tee boxes are red.

Holes
The yardages listed for each layout may differ due to variable pin locations.
