Sanjay Gandhi Biological Park is Patna's main zoo and botanical park, a large green enclosure in a city where shaded public space is valuable. Animal exhibits, lake areas, gardens, and long paths make it a practical family outing rather than a quick monument stop.
It is not as historically important as Patna's ancient and colonial sites, but it does serve travellers who need a slower, greener break from traffic and dense streets. Visit early in the day if you want cooler walking and a more local atmosphere.
