Prepositions of Movement: to
and No Preposition
We use to in order to express movement toward a place.
She's going to the dentist's office this morning.
Toward and towards are also helpful prepositions to express movement. These are simply variant spellings of the same word; use whichever sounds better to you.

With the words home, downtown, uptown, inside, outside, downstairs, upstairs, we use no preposition.

The following prepositions show movement toward something:
To Used to show movement towards something He ran to school.
Onto Used to show movement towards a surface He put his cup onto the table.
Into used to show movement towards the interior of a volume He jumped into the pool.
The preposition to also shows direction when used with verbs of motion: move, go, transfer, walk, run, swim, ride, drive, fly, or travel. The preposition toward can be used also with these verbs except transfer. To is used to show a specific location. Toward is used to only show a general location.
Drive to the house.
Drive toward the house.
Correct: He will transfer to another bus.
Incorrect: He will transfer toward another bus.
(Transfer means to go from one place to another, specific, place so toward cannot be used.)
Another use of to is to show a goal that will be reached. For a physical place, the form is to plus a noun: to work, to school, to the library. For a purpose or reason, the form is to plus the infinitive of a verb: to go, to get, to reach.
Every morning she goes to work.
He washed his car to get rid of the mud.
