Exploration Tour (2020)

The Exploration Tour was the twenty-second tour of Mario Kart Tour, which began on July 15, 2020 and ended on July 28, 2020. Due to its theme around exploration and treasure-hunting, Captain Toad and Toadette in her explorer gear from Captain Toad: Treasure Tracker were added as the new spotlight drivers of the tour, while also adding appropriately-themed kart parts such as the Clackety Kart and the Treasure Map. Choco Mountain from Mario Kart 64 reappears as the signature track of the tour since its last appearance in Mario Kart DS. The menu's background featured the mountains from Choco Mountain as the landmark for this tour. This tour also featured a Heavy Hitters Pipe, a pipe that focused on heavyweight drivers, and became available on July 19, 2020 and ended on July 23, 2020.

Signature kart sets
In every cup, the driver which the cup is themed about is raised a tier on each track, making them a three- or two-item driver on that course. Up until the Ice Tour, a kart and a glider were also given a bonus for each race in the cup.

Rewards
Gold cells indicate rewards exclusive to Gold Pass members.
