A little known plantation tour outside Catadupa is http://www.croydonplantation.com/
It is also the birthplace of Sam Sharpe and there is a church nearby where Sam Sharpe preached which was a catalyst for the Sam Sharpe Rebellion of 1831 in Kensington St. James.

If you go, go early and spend a whole day wandering the 130+ acre working plantation.
