You don't have to go far to see the country's second largest population of bald eagles. Just head north from St. Louis to the Great River Road and make your way to Alton and Grafton, Illinois. Each year, thousands of eagles migrate to the area. They come for the fish found in the cold waters of the Mississippi and Illinois Rivers. The birds begin arriving in late December and stay until March, so there's plenty of time to do a little eagle watching. Below are some of the best places to see the eagles in the St. Louis region.

You can also sign up for guided eagle tours or pick up a copy of the center's eagle watching guide before heading out to do some exploring of your own. The visitors center is at 200 Piasa Street in Alton.​

Brussels Ferry

The area around the Brussels Ferry attracts many bald eagles throughout the winter, but riding the ferry is an experience itself that shouldn't be missed. The free ferry is located on the Great River Road, one mile west of Grafton and four miles east of Pere Marquette State Park. It crosses the Illinois River every day (weather permitting). Just drive your car aboard and let the tow boats do their work. The trip across the river only takes a few minutes, but you may have to wait to board during peak times. Conservationists say you'll often see eagles around the Brussels and other ferries because they churn up the water and bring fish to the surface for the eagles to eat.
