Restrooms at Button Rock Preserve will open for the summer season on Saturday, April 10. Restrooms were closed for the winter season following a temporary closure due to public health concerns related to COVID-19. There are two vault toilets located on the main access road within the preserve. Visitors are encouraged to bring their own hand-sanitizer and practice Leave-No-Trace practices (e.g. packing out all litter and waste) when recreating in areas without restrooms to help protect the North St. Vrain watershed. The watershed provides drinking water to the communities of Lyons and Longmont.
