In Dragon Quest 11 Echoes of an Elusive Age, there are 58 achievements to be unlocked and Mount Olympian is one of achievements that require you to ride all rideable monsters.
Since there are only few mountable monsters, this task is not that difficult - assuming you know the locations of these mountable mounts. Below we show you the locations of all six ride-able monsters in the DQ 11.
Please note that you will not be able to take these monsters with you on your journey. They don’t leave the area assigned to them and you have to leave them behind if your adventure is to continue. So if you find a mountable monster, try exploring the entire area before leaving the mount.

On the lower level of the king's temple (King's Barrow) you will find this ominous mount. With his strong legs, you can jump to higher places (you need to press R2 button)
