Nice day out. The walk through tunnel is fabulous, two beautiful turtles and sharks swimming over your head, very relaxing. There are also a family of seals, and they’re great fun to watch. It’s not a huge place, we walked around a few times while there, but could have spent most of the day in the tunnel. The cafe wasn’t briliant, but as it’s in the centre of Brum there’s loads of good places to eat.
