Lough Derg (of Shannon) is a medium-sized lake in Ireland. The landscape there is hilly terrain with forest and fields. Also the dinghy sailors there beach only at small marinas, that are Portumna, Killaloe, Dromineer, Terryglass, Mountshannon ja Garrykennedy at least.
I participated to a Wayfarer International Rally in Ireland in autumn 2015. We sailed there around 10-20 nautical miles every day. I wrote a summary style article of my visit there.
