Hi Rashid
If the connection between your 2 sites is a layer 2 connection then yes you set this link up as a trunk and pass multiple vlan traffic.
If the sites are on different subnets though why do you want to do this. Remember that a trunk runs at Layer 2 and so Spanning-tree will extend between your sites.

I understand why you want to do this now. The question remains the same, what type of connectivity do you currently have between your sites. Is it yours or is it provided bt an SP.
As Mounir suggested if it is ISP owned you can talkt to them about Q-in-Q and you could also look at L2TPv3 which allows you to extend a layer 2 vlan across a layer 3 link.

What is the intermediate connectivity type? your provider can offer Q-in-Q for such case if they support it.
