Depends on how much you were looking forward to your walk @Bunniekins 

Whether it's in a nice place (scenery etc), where you would still enjoy walking on your own.

The purpose of your walk is the deciding factor.

In my case, such an activity would be mainly for social interaction (connection) - so I wouldn't see any point in walking on my own.

Exercise I am not lacking in - meaningful social interaction & connections (very lacking).
