My good friend Natalie recently had a little girl Zoe so we invited them to join one of our our playground jaunts. Walter Haas is gorgeous. It is situated next to Billy Goat Hill in Diamond Heights and a stone’s throw from Glen Park Canyon. There is a sand pit and expansive play structures for toddlers and older kids. Zygie loved swing and sliding. He mostly played in the sand pit and.took in the views.
