As you can see in the devise source if you navigate to the sign_up it executes the before_filter require_no_authentication and this redirects to the root path which you can find here.

You don't need override registration_controller, you can change only your custom registration_controller that echo original registration_controller.

class Admin::RegistrationsController < Devise::RegistrationsController
  layout 'admin'
  prepend_before_filter :require_no_authentication, :only => []
  prepend_before_filter :authenticate_scope!
end
