Some time ago I wrote the following for myself, and I find that I use
these bindings several times a day.

(defun my-org-skip-forward (arg)
  "Move forward to the next visible 2nd or greater level heading,
skipping headings of the same level as the starting position"
  (interactive "p")
  (let ((initial-level (org-outline-level))
        (done nil))
    (while (not done)
      (outline-next-visible-heading arg)
      (let ((level (org-outline-level)))
        (when (and (> initial-level 1) (= level 1))
           (setq initial-level -1))
        (setq done (or
                    (and (< arg 0) (bobp)) 
                    (and (> arg 0) (eobp))
                    (and (not (= level initial-level)))))))))

(defun my-org-skip-backward (arg)
  (interactive "p")
  (my-org-skip-forward (- arg)))

The idea is that point is moved to the next visible boundary where
outline level changes. This is useful when you have your file in
collapsed state with only a few trees expanded. Above command allows
one to quickly jump between such trees.

Also useful for navigating result of a sparse tree search in the same
