You can always create your own recursive function, in my case I do as the code as follow.

first();

        if (!$lowestLevel) {
            return $tree;
        }

        $tree[] = $lowestLevel->toArray();

        if ($lowestLevel->parent_id !== 0) {
            $tree = Location::getTree($lowestLevel->parent_id, $tree);
        }

        return $tree;

    }

}
