The Carty Unit is your gateway to nature and cultural connection to the land we now call Ridgefield National Wildlife Refuge. Plenty of parking and restrooms can be found just past the entrance sign. From the parking lot, head over the footbridge to begin your Refuge adventure. Have a question? Refuge staff are available in the small office building, Monday-Friday from 7:30am to 3:30pm. There is a $3 fee to enter the Refuge beyond the parking lot, which helps fund public programs. Look for the fee station in the parking lot, near the restrooms.
