The Village of Oak Park provides free transportation service via The Oak Park Shuttle. This shuttle is a passenger van that operates on an hour-long looped route that connects major points of interest throughout the village. It stops at set locations every half hour.
The main points of interest that it serves are:
The Avenue District
Oak Park Public Library
Downtown Oak Park
Frank Lloyd Wright Home & Studio
CTA Green Line El and Ridgeland Stop
We stayed at the CARLETON HOTEL, and there was a stop right outside the entrance to the hotel, which was quite convenient.
Note: parking is difficult in Oak Park, so either take public transportation or stay at a hotel with parking With this shuttle service, there is no need for a car. We walked to all the above mention locations so it's not necessary to use the shuttle all the time.
There are two different shuttles called Shuttle One and Shuttle Two. You are able to transfer between them on every hour and half hour along Oak Park Avenue and South Boulevard at Stops 1-13.
Shuttle One: Starts at 10 a.m. at Stop 1 and ends at 5 p.m. at Stop 1
Shuttle 2: Starts at 10:30 a.m. at Stop 1 and ends at 5:30 p.m. at Stop 1
Thursday and Friday evenings from Memorial Day through Labor Day the hours are extended to 9 p.m. and 9:30 p.m.
I was impressed with this free service which is convenient and well run.
to get to Oak Park on the subway (El), take the GREEN line. get off on the 2nd stop from the end. It's the OAK PARK stop. when you get off the subway, go down the stairs and turn left. Walk a block or two and you'll see the better part of Oak Park. From downtown Chicago, it takes about 20-25 minutes to get here.
Frank Lloyd Wrights home are about 3 blocks north and 3 blocks to the west of the stop.
Hemingway's home and museum is on Oak Park avenue about 3 blocks north of the station.
Provided that you are not averse to a bit of walking, I would suggest ignoring the directions given on the CTA's website that either have you transferring several times if you say you want to walk less than a 1/2 mile or says to take the green line el (subway) to the Harlem stop. Instead I would recommend taking the green line el to Oak Park Avenue which is about the same distance away as Harlem but a much nicer street to walk down. The CTA's website says it a .7 mile walk from the el to the Frank Lloyd Wright Home & Studio at 951 W. Chicago Avenue, Oak Park Avenue has shops and restaurants and turns into a pretty tree lined street.
Oak Park is 12 miles west of downtown Chicago. If you are driving, take highway 290 west from downtown to Harlem Avenue which is a left hand exit from the highway. Turn right (north) at the top of the ramp and take Harlem to Chicago Avenue (which is one street after the sign that says turn here for the visitors center). Go about 3 blocks to 951 W. Chicago, the Frank Lloyd Wright Home & Studio, which is the place to start your visit to Oak Park. I was able to find street parking which is not restricted on the weekends, on the weekdays watch the signs as some of it is limited to 2 hours between certain hours.
