Mystery Land is a board set in some ancient ruins in Mario Land in Mario Party 2, and features several Mario-based parodies of real-life cryptozoological and historical mysteries. It is divided into four areas, to which people warp to each time they land on a Happening Space. They can also pay 10 coins to have a Bob-omb UFO take them to another area, but sometimes the UFO will malfunction and take the player to a small area with ruins resembling King Bob-omb. Other interesting features on this board include the Shy Guy's Curse House, where a player can pay 5 coins to curse themselves or another player to reduce the number on their dice block to 1-3, rather like the Poison Mushrooms and Cursed Dice Blocks from later Mario Party games. The Item Minigame is Mallet-Go-Round, and the Duel minigame is Psychic Safari.

At the end of the game when Toad is about to announce the winner, he is interrupted by a red Koopa Troopa who comes and alerts the players that the treasure has been found. A cutscene then shows a green Koopa with a golden Bob-omb statue. Then the villain of the board, the Bowser Sphinx, comes to challenge the Koopa to guess a figure shrouded in shadow. The Koopa guesses incorrectly, saying that it is a cow, and Bowser curses the Koopa by trapping him in a rock. Then, the winner of the game comes to confront him. The winner guesses Bowser's shadow riddle correctly, saying that the figure is him. The Bowser Sphinx disappears, a consequence of having his riddle guessed, and the statue breaks to reveal a Bob-omb Buddy that was trapped inside. The other Bob-omb Buddies come to take their rescued comrade away on their spaceship and takes Bowser in their custody. The winner of the board is then congratulated by the other players, Toad, Koopa, and a Star.

The Item Shop is here, and there is a door which allows players to willingly access the upper left or bottom right area if they have a Skeleton Key.

King Bob-omb ruins area
This small area is not normally accessible, but a player may be randomly sent here after summoning a Bob-omb UFO. It consists of nothing but Red Spaces and Happening Spaces. A statue of King Bob-omb can be seen in the central sinkhole.

Trivia

 * Wario's outfit for this board somewhat resembles his normal form from Wario Land: Super Mario Land 3. This is because the player wears an archaeologist attire complete with a sun helmet, whereas Wario is seen wearing such a helmet in said game.
 * On a similar note, Mario's outfit for Mystery Land resembles the outfit Mario wore in Mario's Picross.
 * Also, Bowser's Sphinx costume for this board somewhat resembles his Koop Tut alter ego from The Super Mario Bros. Super Show! episode, "The Ten Koopmandments".
 * In the ending for the board, when Sphinx Bowser gives a riddle, Koopa's (incorrect) answer was a cow, with the actual answer being Bowser himself. This was a subtle reference to Bowser's design process, where Shigeru Miyamoto initially envisioned him as an ox, but ultimately worked with Takashi Tezuka to mix both turtle and ox designs for his final design.
 * The menu icon for this board resembles the condor figure at the.
 * Despite the fact that this board has the fewest spaces of all boards in the game, Mystery Land has more Happening Spaces than any other boards.
