EF code-first: How to load related data (parent-child-grandchild)?

Question

I have this entity:

public class DynamicPage {

    public int PageId { get; set; }

    public int Order { get; set; }

    public string MenuText { get; set; }

    public string MenuHover { get; set; }

    public int? ParentId { get; set; }

    public virtual DynamicPage Parent { get; set; }

    public virtual ICollection<DynamicPage> Children { get; set; }
}

This entity may have 3 level: Parent -> Child -> Grandchild. How can I load the Parent (level 1) whit all associated children (level 2) and for each child, associated grandchild (level 3) if any? Thanks to help.

EF 4.1 feature and syntax:

var entity = context.Parents
    .Include(p => p.Children.Select(c => c.GrandChildren))
    .FirstOrDefault(p => p.Id == 1); // or whatever condition
