Head South down the lane to find Necarne Castle. Also known as Castle Irvine, Necarne Castle was built in the 17th century as part of the plantation of Ulster. In 1831, Irish novelist and playwright John B. Keane designed the beautiful two-storey facade which gives the castle its Victorian image. The castle passed through the hands of various owners before being requisitioned by the United Stats army in 1941. It functioned as a military hospital during the Second World War before falling into ruin. Over the last decades, the castle was used by Enniskillen Agricultural College. However, it now stands empty once again and is up for sale. You can't visit the interior of the castle, but you can freely visit the lovely parklands and admire the building from afar.

A hive of activity, the marina at Castle Archdale is full of things to do. Why not park your bike and pedal on water on one of the hydrobikes? Kayaks, paddleboards and boats are also available to hire. Or if you're looking for a break, this is a great place to stop and take it all in.

During WW2 Castle Archdale was a major base for flying boats and housed up to 2,500 people. Buildings such as these would have been a central location for the RAF fighters who lived here. Sometimes exhibitions are held in these courtyards to display some of the key historical notes of the use of this area during the war.

Beautiful views over Lough Erne toward Tom's Island. Tom's Island is actually no longer an island, but once was before the lough was lowered.

Take in the fabulous views of Lower Lough Erne from this point. Directly ahead you will see Crevinisaughy and Inishmakill island. These are one of the many islands found in this large lake system that is in fact widened sections of the River Erne as it flows towards the Alantic.
