Rinn Dúin is a walker's delight and home to Warren Point and Castle looped walking trails, which have opened up this tranquil farmland peninsula to the interested visitor.

Walking here, you get a sense that past and present are closely interwoven. You will be captivated by the fascinating remains of an Anglo-Norman castle and walled town. Built in 1227 by King Henry III of England, it was populated by up to 1,000 people in its heyday. It was destroyed, ruined, and forgotten in less than 150 years, but in recent times one of the most important medieval town sites in Ireland has recently found a new lease of life.

Six hundred and fifty years after it was destroyed and forgotten, St. John’s Parish Heritage Group has facilitated the conservation of the medieval town walls and the parish church. Situated on Lough Ree about 10mi by boat or car from Athlone, it lies near the village of Lecarrow in St. John's Parish in South Roscommon.

From a few dozen academic visitors a year in 2007 to 6,500 visitors in the year 2011, Rindoon is a national cultural tourism treasure just waiting to be explored.
