If you're ever traveling on I-80 and at the Mississippi River, definitely stop at the Mississippi Valley Welcome Center, high atop the bluff on the Iowa side and with a great view of the river and bridge.
My wife and I have been stopping here on all our eagle watching trips the last several years after a read an article about it in the Chicago Tribune. It is sponsored by the nearby Quad Cities, a great destination in itself.
During the summer, there is a great veranda to view the river. They even have free coffee and, of course, all that travel information. Their bathrooms are huge and extremely clean.
It is open year-round except Thanksgiving, Christmas, New Years Day and Easter.
We always like to look at the eagle stuff and usually end up spending some money. There is also lots of keepsakes, antiques, Iowa souvenirs and what I'd call a mini-museum.
Located at 900 Eagle Ridge Road, LeClaire, Iowa, 800-747-7800 ext. 120.
