The Morton Arboretum is a 1,700-acre living museum in Lisle, Illinois, about 25 miles west of Chicago

The Morton Arboretum sits on the grounds of a former estate and holds over 4,000 types of trees, shrubs, and plants from around the world. It is open to the public year-round, though hours and which areas are accessible change by season. Admission costs money — the amount varies depending on whether you visit on a weekday or weekend and whether you are a member.

The grounds are designed so you can walk, bike, or drive through different sections. Most visitors spend two to four hours there, though you can spend a full day if you explore slowly. The arboretum also runs classes, lectures, and guided tours throughout the year, some included with admission and some requiring separate registration and payment.

Key Takeaways

  • The Morton Arboretum charges admission on a sliding scale depending on the day of the week and your membership status, with discounts for Illinois residents, seniors, and children.
  • You can explore the grounds on foot, by bicycle, or by car, and the terrain ranges from flat paved paths to steeper natural trails.
  • Parking is free, and the arboretum provides maps at the entrance so you can plan which sections to visit based on your time and physical ability.
  • Seasonal changes mean some paths and gardens are closed during winter, so checking the website before you go tells you what will be open on your visit date.
  • Dogs on leash are permitted on most trails, but the visitor center and some garden areas are off-limits to pets.

Admission prices and who gets discounts

Admission is charged per person and varies by day of the week. Weekend and holiday rates are higher than weekday rates. Illinois residents receive a discount on both weekday and weekend admission. Seniors (usually age 65 and older), children ages 2 to 17, and students with valid ID also receive reduced rates. Children under 2 are typically free.

If you plan to visit more than twice a year, membership may cost less than paying admission each time. Members also get free parking, discounts at the gift shop and cafe, and access to special member-only events. The arboretum offers different membership levels at different price points, and you can join at the gate or online before your visit.

How to get there and where to park

The Morton Arboretum is located at 4100 Illinois Route 53 in Lisle. If you are driving from Chicago, take I-88 west and follow signs for Route 53 north. Parking is free and located near the main visitor center. The lot fills on busy weekend days, especially in spring and fall, so arriving early in the day improves your chances of parking close to the entrance.

Public transit is limited. Metra commuter rail stops in nearby towns, but you would need a car or taxi to reach the arboretum from the station. Most visitors drive. Bicycles are permitted on designated paths, and some people bike from nearby residential areas, though there is no dedicated bike path from major roads.

What to expect on different types of trails

The arboretum has over 16 miles of paths. Paved paths near the visitor center are flat and accessible for strollers and wheelchairs. Natural trails deeper in the grounds are narrower, unpaved, and include hills. The arboretum provides a map at the entrance showing which trails are paved, which are natural, and which allow bicycles.

Most visitors stick to the paved sections and the easier natural trails, which take one to two hours to walk. If you have limited mobility or are with young children, you can see a substantial portion of the arboretum without attempting the steeper trails. The grounds are open from sunrise to sunset, though the visitor center and facilities close earlier.

Seasonal changes and what blooms when

Spring (April through May) brings flowering trees and shrubs — crabapples, magnolias, and lilacs are at their peak. Summer (June through August) features green foliage and flowering perennials, though some areas can be crowded and hot. Fall (September through November) offers changing leaf color, which peaks in mid-October. Winter (December through March) shows the structure of bare trees and evergreens, and some paths may be closed due to snow or ice.

If you want to see a specific plant in bloom, the arboretum website lists what is currently flowering. Some sections are closed seasonally for maintenance or because plants are dormant. Checking the website before you visit tells you which areas will be open and what you are likely to see.

Facilities, food, and what to bring

The visitor center has restrooms, a gift shop, and a cafe that serves sandwiches, salads, and beverages. The cafe is open during regular arboretum hours, though hours may be shorter in winter. You can bring your own food and eat at picnic tables scattered throughout the grounds. Water fountains are located near the visitor center and at a few other spots, but not on all trails, so bring a water bottle if you plan to walk for more than an hour.

Wear comfortable walking shoes with good traction, especially if you plan to use natural trails. Sunscreen and insect repellent are useful in warm months. The grounds offer little shade on some paths, so a hat or umbrella is practical. In winter, paths may be icy, so boots with grip are important.

Rules for pets and other restrictions

Dogs on leash are permitted on most trails and paved areas. The visitor center, cafe, and some garden areas are off-limits to pets. Cats and other animals are not permitted. If your dog is aggressive or not reliably under control, the arboretum asks that you not bring it, as other visitors and their pets share the trails.

Bicycles are permitted on designated paths only — not on natural trails or in garden areas. Skateboards, roller skates, and motorized vehicles (other than wheelchairs and mobility devices) are not permitted. Picking plants, collecting seeds, or removing anything from the grounds is prohibited. Photography for personal use is permitted, but commercial photography requires permission.
