Start your visit to Cuyahoga Valley National Park at Boston Mill Visitor Center. Meet park staff, get questions answered, and learn about the park and places to visit. The visitor center is open daily from 9:30 am to 5 pm, March through December. January and February, hours are shortened. For the summer season, hours are extended and additional staff are available outside the visitor center to assist with trip planning, weather permitting. Restrooms stay open even when the visitor center is closed.
