Visitor Tips

  • Check Hours and Admission: Always verify the latest operating hours, admission fees, and any special event schedules on the garden's official website before your visit.
  • Dress for the Weather: Many gardens have extensive outdoor areas. Wear comfortable walking shoes and dress appropriately for Indiana's weather conditions, including sun protection or rain gear.
  • Stay Hydrated: Bring a water bottle, especially during warmer months, as you'll likely be doing a lot of walking.
  • Photography Etiquette: Most gardens welcome photography for personal use, but be mindful of other visitors and respect any restrictions on commercial photography or drones.
  • Respect the Plants: Stay on designated paths, do not pick flowers or disturb plant beds, and leave no trace behind.
  • Plan Your Route: With larger gardens, consider looking at a map beforehand to prioritize areas you wish to see, especially if you have limited time.
  • Family-Friendly Activities: Many gardens offer children's gardens or specific activities for younger visitors. Check their programs if you're visiting with family.
