Is the Navy pier open all day? What's open and closing time

You can check in the web.

I believe 7 pm

I think they close till sunset not really sure

Depends on what u r looking for. Stores, museum etc start closing from 5pm onwards. Architectural tours stay till late. When fireworks are on, boat tours stay open till 9:30pm. Restaurants, eateries can also be found open till late.

I think they close at 10:00p.m.

Yes it's usually open all day it's pretty happening in the afternoon and late afternoon as an amazing spot to go check out the lake see all the buildings and all the good things that around the pier you got numerous options for food bars boat rides shopping a kids museum I believe all kinds of activities the fun of Chicago
