Grandspan

Grandspan is the footbridge that cuts across the Tawe estuary in Swansea, and it's one of those structures that makes you stop and actually look at something you'd normally just walk past. The arch is genuinely striking - all clean lines and that pale concrete that photographs well in decent light. It connects the city centre to the Marina, which means you're essentially crossing between two completely different sides of Swansea in about five minutes on foot.

The walk itself is the draw here. You get proper views down the estuary on one side and back towards the city on the other. On a clear day you can see across the bay properly. The span is wide enough that you don't feel squeezed in, and there's something rather pleasing about being suspended above the water like that - the kind of moment where you actually notice you're moving through a landscape rather than just being in one.

It's free, obviously, and you can cross it whenever. There's no faffing about with opening hours or tickets. Twenty minutes is plenty if you're just doing the crossing, but if you're staying at SWDA Riverside or Riverside Holiday Park just up the coast, it makes a lovely addition to a day exploring Swansea. Families will find it easy enough, though there's not much to stop and do once you're on it - it's a corridor, really, not a destination. That said, as a piece of engineering that actually works as a pleasant walk, it does the job well. Worth the detour if you're in the area.
