Nothing spectacular in the GKVK campus. You've got a railway track/over-bridge, lots and lots of trees, a mango grove, a couple of play grounds, a small temple, a few buildings and basically that's it. The birds have migrated due to extreme heat. You'll surely get a few cattle egrets and a few spotted doves if you are lucky. But it is a nice place for a morning walk. Worth exploring once. And yes a good place for macro photography.
