According to Michael Swan (Practical English Usage)
the adjecive near can be used like a preposition with or without to. To is not normally used when we are talking about physical closeness.
We live near the station.
When we are not talking about physical closeness, near to is often preferred.
I came very near to hitting him.
Nerarer and nearest are generally used with to, though to can be dropped in an informal style.
Come and sit near (to) me.
Who is sitting nearest (to) the door.
Hope it helps you.
