The fortifications around Valletta offer amazing walking with harbor and countryside views. Most tourists stick to Upper Barrakka Gardens but you can walk much further along the walls.

The Spur trail starts near the gardens and takes you around the southern fortifications. About 2km total with several viewpoints looking across to the Three Cities and out to sea. Minimal elevation change despite being on the walls.

Bring water and sun protection - very little shade along the route. Early morning or late afternoon timing is best for both light and temperature. Free activity with arguably better views than any paid attraction.
