There are some lovely swim locations around Sligo, like the placid and frondy Lough Arrow on the N4 (part of the lough lies in County Roscommon):

Glencar Lake was complete autumnal serenity and a recommended swim:
And Lough Owel, on the road home through Westmeath, was rosy and gorgeous, a spectacular swim jetty (this may be the top swim):
