Get Directions

The majority of Sandy Island Eagle Sanctuary was donated by Missouri photographer Frank Oberle and his wife Judy in 1992 as a safe habitat for bald eagles. This natural area is only miles from St. Louis, making it an accessible and reliable place to observe these majestic birds in their winter habitat.

Why You Should Visit

Sandy Island provides critical habitat for wintering bald eagles that visit this region of the Mississippi River. The Mary Chambers Wiese platform located adjacent to the preserve, provides close-range viewing (complete with mounted scope) of the eagles and other birds. Please note: The preserve is closed to the public during the months of November through March to prevent disturbances when the eagles are roosting.


Minutes from the St. Louis metropolitan area, just south of  Winfield Lock and Dam, three miles east of Winfield, Missouri on Highway N.




28 acres (includes a quarter mile of frontage along the Mississippi River just below the dam)


Visitors can visit and walk along the levee and picnic areas to view the eagles.

What the Conservancy Has Done/Is Doing

The Mary Wiese Observation Platform is located on Corps of Engineers property at the south end of Lock and Dam #25.


What to See: Animals

During the winter months, up to several hundred bald eagles use the preserve's cottonwood and silver maples trees for roosting. January and February are prime viewing times.

What to See: Plants

From the tall trees, the eagles scan the open water below the dam, where they dive to catch fish.

Check the local weather forecast and dress accordingly. No special gear or clothing is recommended.
