Important Transportation Information: We have been made aware that the main entrance to the Trempealeau National Wildlife Refuge will be redone in the spring/summer of 2024. We do not yet have details on the length of the project or when this will occur. We have been made aware that we may need to drive into the Refuge through the Marshland Access (off of Highway 35/Great River Road near the Hillside Fish House) to get to the OWL building. This may add or subtract 5-10 minutes from your travels, depending on which direction you typically come from! If you have questions, let us know. We will send out more information about this as soon as we have an update to share.
