I may be in St.louis around the first of May to attend a concert. I am looking for other cool things to do. Any ideas would be appreciated.

Survive

Listed as one of the most dangerous cities in the US , you could play " dodge the gang banger "

Zoo is nice, one of the better ones. it's free to get in other than if you park in their lot you have a small charge.

If you like baseball and can go, Busch stadium atmosphere is always a good time, ball park village outside is fun, bars, bands, and shops. well use to be until the cards sucked and no one likes the manager, and whatever John mo wants to call himself.

zoo and botanical garden

We had thought about the zoo. We both like animals.

Look at it in the mirror.
I think there is a big aquarium there of some sort.
And the arch of course

I forgot that they put that aquarium at union Station. I'm going have to check that out myself.

Take a tour with this guy

They also have upper Mississippi River cruise, not sure how much money you want to spend or time you have but I've always wanted to do one of those.. leaves from st.louis and go to st.paul MN I believe.

Stay out of St Louis is the best thing to do there

The aviary (a place where birds fly around free in a large enclosed space) is cool. It is a leftover from the 1904 Worlds Fair.

Walk around the streets saying "Show Me" .

Go to see the Clydesdale breeding facility. Busch gardens. If you like to fish, book a trip to go catch some blue cat on the Mississippi.

Definitely go to ‘The Hill’ for authentic Italian.

Not sure where you'll be staying, and some good ideas listed, BUT:

Be out of the city by dark
Lot's of crime around the Ball Park, especially at night.

Union Station has the Aquarium and a HUGE Ferris Wheel.
St. Louis Zoo is worth the trip, go early, The Aviary is there.
No end of good food places
Ted Drews ice cream is a cult favorite
Harbor tours and Helicopter rides on the River front at the Arch
The Arch
Forest Park has the Zoo, The Planetarium, The Art Museum, and a bunch of other museum's, site of the 1904 Worlds Fair. Had a bunch of kool statues, but the libtards had them removed.

If your driving, The Confluence of the Mississippi and Missouri Rivers has 2 state parks and is neat to see.
The bridge over the Mississippi at W Alton, along with the natural area there
The old Route 44 Bridge over the Mississippi at Chain of Rocks
The winter encampment of Lewis and Clark on the Illinois side at Chain of Rocks
Cahokia Mounds National Park, in Illinois

French Quarter in St. Charles, lot's of small shops, antiques and food etc
Gambling boats (sic) and Casino's
Bass Pro shop and a Cabelas not too far away.
You said concert, the big one is located near here at 270 Hwy and 141 Hwy.

Good luck and hope you have fun.

My wife's favorite Brazilian steakhouse is tucanos it's technically in St Charles at by where the Missouri in the Mississippi meet will you eat there every time we're in the area sometimes it's primary reason to go and we tag other things along.

With kids the children's museum science center zoo for the wife botanic gardens tucanos etc. I'm surprised with all the people talking about how dangerous it is I walk around downtown St Louis all the time. There's a difference between St Louis and East St Louis which is actually across the river in Illinois.
