Open daily May 1 - October 31, 9 a.m. - Noon, 1 p.m. - 5 p.m. Guided tours only. Tours start at the top of each hour at the Interpretive Center and last about 45 minutes (last tour at 4 p.m.). Free tickets for the tour can be picked up at the Interpretive Center.
It is well worth the tour.
May through October I believe.
Lyndon has provided the best answer, but apparently yes, thru the end of October. Good to call ahead and reserve tour space. Very interesting historically if you like history.
