If you want to start your day in the early 1900s, WW1/1916 Rising visit (WW1/10(http://www.cavanmuseum.ie/) just a few miles away in Ballyjamesduff...then become part of 3000BC, at loughcrew, within 15kms, about 25minutes drive, (https://heritageireland.ie/places-to-visit/loughcrew-cairns/) and finish your day sampling amazing local food, (www.riverfront.ie) ...then my home is the place to be.
If learning a traditional Irish craft (knit socks, spin wool) is something you think you might like to experience....less than 20 minutes drive..( www.craftsofireland.ie/product-category/workshops/)....I mean why just watch a demonstration when you can actually learn how to do it? then let my home be your base.
If golf is on your wish list you won't be disappointed....perhaps challenge yourself at the PGA National Ireland Slieve Russell golf course? or 2 other courses within 20 minutes drive.(Virginia & Cavan)....even better there is an 18 hole course less than 10 minutes drive from my home, (1 round only €15 per person), 18 holes a bit much, then 9 holes is also available at the Crover House Hotel...booking available online.

However, why not venture an little further afield to the famous Phoenix Park Dublin..www.phoenixpark.ie. The Phoenix Park is one of the largest enclosed public parks in any capital city in Europe....It was originally formed as a royal hunting Park in the 1660s and opened to the public in 1747. A large herd of fallow deer still remain to this day. The Park is also home to the Zoological Gardens, Áras an Uachtaráin, (that's where the President of Ireland lives) and Victorian flower gardens. The Phoenix Park is only a mile and a half from O’Connell Street.
