From here over the Lough you can see St Patrick's Purgatory which is an ancient pilgrimage site that is suggested to have not been interrupted for fifteen hundred years, with it continuing in the present day. Its importance in medieval times is clear due to its present on maps all over Europe as early as the 15th century. It was the only Irish site designated on Martin Behaim's world map of 1492.

Built in the 17th century, Castle Caldwell was part of the Ulster Plantation, a province of Ireland colonised by British settles throughout King James I era. The castle had a number of inhabitants after that and fell into ruin towards the 1800s. Although access to the castle is now forbidden due to its dangerous state of repair, the surrounding park and forest can be explored freely. Keep your eyes peeled for the ruined chapel and overgrown graveyard.

Surrounded by green rolling countryside, Roogagh Waterfall is a pretty nature spot on the outskirts of Garrison village close to Lough Melvin. There's a short walk that leads along the river and through woodland to reach the falls. You can pick up supplies in Garrison to enjoy a packed lunch overlooking the cascading water at one of the numerous picnic benches.
