Does anyone know if there is park./garden where it is allowed to have a picnic?? Location: Balboa Park, San Diego, CA|||you are allowed to picnic anywhere in balboa park (except inside the museums, of course). it's a beautiful park. i would recommened in front of the fish pond outside of the museum of art, i believe. also, there are gardens and trails all over the park. in addition, if you are going with kids there is a wonderful playground.
