Consider a lap around the track in a pace car for an unforgettable thrill.
Stroll Through White River State Park's Gardens
Escape the urban bustle in this sprawling urban oasis, home to the serene Japanese Garden and the vibrant Indiana Native Plant Society Garden.

Essential Travel Tips
You absolutely *have* to try a Pork Tenderloin sandwich while you're in Indy! It's a local obsession. Look for places like 'Steak 'n Shake' (yes, the chain, but it's a local favorite for this!) or smaller diners; they're usually huge, breaded, and fried, often served on a bun. Just be prepared for a delicious, messy, and very filling experience.
While downtown Indy is quite walkable, consider renting a Pacers Bikeshare bike to explore further afield, especially along the Canal Walk or to get to neighborhoods like Fountain Square. It's super affordable and a great way to see the city without worrying about parking or expensive ride-shares for short hops.
Many of Indy's best attractions, like the Indianapolis Museum of Art at Newfields or the Children's Museum of Indianapolis, offer free admission days or discounted hours. Check their websites before you go; planning around these can save your family a significant amount of money, especially if you're visiting with kids.
Indianapolis has a surprisingly vibrant arts scene, particularly in the Mass Ave and Fountain Square districts. Don't just stick to the big museums; pop into the smaller galleries, catch a show at the Phoenix Theatre, or check out the street art. You'll discover local talent and get a real feel for the city's creative pulse.
Indy is generally a safe city, but like any urban area, be aware of your surroundings, especially at night. Stick to well-lit, populated areas when walking after dark, and don't hesitate to use a ride-share service if you feel uncomfortable. Downtown is usually bustling, but venturing into less familiar neighborhoods requires a bit more caution.
Indiana weather can be unpredictable, so pack layers! Even in summer, evenings can cool down, and spring/fall can bring anything from sunshine to chilly rain. Comfortable walking shoes are a must, as you'll likely be doing a good amount of exploring on foot, especially around Monument Circle and the Canal.
