Horses, like most mobs, can ride in a minecart and a boat. Adult horses cannot ride in boats.
Tame the Horse
First, select an empty slot in your hotbar (because you must use your hand to tame the horse). You will tame a horse by repeatedly trying to mount the horse and getting bucked off. The game control to tame the horse depends on the version of Minecraft: For Java Edition (PC/Mac), right click on the horse.
The rarest regular spawning horse is easily the skeleton horse…
The horses are not tied up with rope and they can be wild or tamed. While playing the game, in both creative and survival mode, when I have moved away from the pen about 150 blocks, then return, the horses can and do despawn. If the horses are wearing armor, they do not despawn.
Chests cannot be placed on horses in Minecraft; they can be placed, however, on donkeys, mules, and llamas by using (typically right clicking) a chest on one of these three types of creatures.
Feeding a horse will make it easier to tame. They will eat wheat, hay bales, sugar, apples, bread, golden carrots, and golden apples. Mules are not found naturally in Minecraft.
