The barrage is like a giant lock, have never seen it open, would be quite impressive. More information boards would be an asset

went here as part of a sleepover at Cardiff bay, stayed at Travelodge. barrage was interesting nice walk too plenty to do around the area, would recommend

This is a lovely walk from the Bay to Penarth with wonderful views of the Bay and Marina. Well thought out as a play ground for the kids, toilet facilities and places to stop and just admire the view.

I love the transformation from what it used to be when we used to go to cardiff docks years ago. My friend and I go down there in the summer a lot

Well worth a visit as part of a walk around the Cardiff Bay area. Interesting to see boats entering the Bay from the Bristol Channel through the lock gates.

a nice walk from penarth to cardiff bay with no traffic to contend with good play grounds if you have children and nice to see kids playing and being kids not bored

This is well worth a visit and is fascinating for young children. One of my favourite things to do is to park my car at the barrage, catch the little land train to the bay and have lunch, then catch boat back. Kids love.

This is such a great walk or bike ride and it is exciting watching the boats go through the locks. A good play area and skate park for the kids as well. There is also a good circular route approx 8 to 10K for a run or cycle if you are up for it.
