Unlike most state parks in Indiana, Fort Harrison is a day-use park, with its only overnight facilities being the inn, The Fort Golf Resort, which was the old officers' club.
The fort's eighteen-hole golf course makes the park popular with Indianapolis golfers; it was redesigned by Pete Dye after the fort's closure, making it a 72-par course.
Only golfers are allowed on the course.
The VIP housing became the Harrison House Suites, and the four Officer's Homes are available for overnight lodging as well.

There are six hiking trails, and one for horseback riding, with horse rentals available.
One of the hiking trails, Harrison Trace Trail, is paved, making it available for bikers and in-line skating.
The longest of the trails is the Lawrence Creek Train, which is a 4.2-mile (6.8 km), single-track trail for mountain biking and walking.
The wildflowers take the place of the ravines and steep hillsides typical of state parks in southern Indiana.
Biking and fishing are also available; the park office sells the necessary state fishing permit.
In winter, ice fishing is available.
An interpretive center at the park office informs visitors of the history and natural environment of the park.

Fall Creek runs for 3.5 miles (5.6 km) inside the park, with smaller tributaries feeding it which are also within the boundaries of the park.
Beaver, deer, frogs, squirrels, and turtles are the most commonly seen wildlife in the park; a heron pond is off-limits for visitors.
