How do I create an extra post page in wordpress [closed]

As I understand you, you need to create a Custom Post Type.

To do this you can paste this into your functions.php file of your template. If you need to know how to improve this custom type you can check the wordpress codex link

function create_posttype () {

register_post_type( 'destinos',
        array(
            'labels' => array(
                'name' => __( 'Destinos' ),
                'singular_name' => __( 'Destino' )
            ),
            'public' => true,
            'has_archive' => true,
            'rewrite' => array('slug' => 'destinos'),
        )
    );
}

add_action( 'init', 'create_posttype' );
