Older cached sources showed a paid admission structure ($5 adult/$4 senior); the current official page and a 2025 season-opening press release both state admission is now free — treated as current since it's the more recent official source, but worth a quick re-check at time of visiting.

Open mid-April through mid-November, Wednesday-Sunday 10am-4pm, with historical interpreters demonstrating milling, spinning, and weaving on Saturdays and Sundays at 2pm. Admission is free.
