Docker cannot `cd` to volume dir - docker

Question

Objective:
Create a docker volume
cd to that volume to check my contents
$ docker volume create hello_world
$ docker volume ls
DRIVER VOLUME NAME
local hello_world
$ docker inspect hello_world

"CreatedAt": "2018-11-19T05:37:03Z",
"Driver": "local",
"Labels": {},
"Mountpoint": "/mnt/sda1/var/lib/docker/volumes/hello_world/_data",
"Name": "hello_world",
"Options": {},
"Scope": "local"
}
]
$ cd /mnt
bash: cd: /mnt: No such file or directory
IF I cannot cd to the Mountpoint then where is it being saved?
Also tried this
$ docker-machine ssh default
