A gentle river-and-fort introduction
Allow 45–90 minutes. Begin at an open, signed public approach, follow the accessible sections of promenade that suit your group, and stop where you can see both the river and the fortress. Compare the wall angles with the curves of the park, then return by the same permitted approach if that is easiest. This is a flexible outing, not a mapped circuit; shorten it for heat, rain or works.
