Dual Riders
Starting from version 1.17, this mod is only required server-side. However, in versions 1.18 and above, it is still recommended to install it on the client to avoid visual errors.

The Dual Riders mod opens up new possibilities for cooperative travel in Minecraft! Now two players can ride on one horse, making world exploration much more exciting and convenient.
The control mechanics are completely similar to boats: the front player controls the direction of movement, while the rear passenger simply enjoys the ride without needing to control the animal.
Using the mod is very simple - just tame a horse, mount it, and your friend needs to simply right-click on the horse to join you.
