We stopped in here on Mother's Day 2017 - after a beautiful day of walking on the Ludovico Sculpture Trail & some geocaching. The museum is housed w/ the Seneca Falls Visitor Center on the main thoroughfare. It was very informative - nice exhibits. We were very surprised at how many businesses used to be based in Seneca Falls!!
The Women's Hall of Fame (across the street), which we didn't visit this time, is in the process of renovating an old building - expected to be completed in July 2017.
We plan on heading back to Seneca Falls during the summer when the canal locks are open and the passenger boat on the canal is operating.
The gentleman who was there mentioned that in season, boaters can dock - for free - along the canal; use the showers in their building; and enjoy the company of other boaters.
Although free, we did leave a donation. It's VERY IMPORTANT to support groups such as this!!!
