About This Route
Boyle was where the great Cistercian monks built their abbey and the MacDermots ruled from their island castle. Today, Lough Key Forest Park offers Ireland's finest forest playground, while Boyle Abbey remains one of the country's best-preserved medieval monasteries.
Why This Route?
Boyle and Lough Key combine history with nature:
- Boyle Abbey - Ireland's finest Cistercian ruins
- Lough Key Forest Park - Premier forest adventure destination
- Island castle - MacDermot stronghold on the lake
- Arigna Mining Experience - Ireland's coal heritage
- Family-friendly - Activities for all ages
Where to Stay
This 65-kilometre day route loops from Boyle through Lough Key Forest Park and the Arigna hills, with a stop at Carrick-on-Shannon. Both Boyle and Carrick are on the circuit, but Carrick-on-Shannon has the larger selection of accommodation and serves as Ireland's cruising capital, making it the more versatile overnight option.
Carrick-on-Shannon
Carrick's colourful quays and riverside restaurants are a natural place to unwind after a day that takes in Boyle Abbey, the tree-canopy walk at Lough Key, and the underground coal-mine tour at Arigna. The town is barely twenty minutes from Boyle, so you can be at the abbey gates early and still have time for Drumshanbo's gin distillery before heading back. Cruiser-hire companies and kayak outfitters along the Shannon quays can also fill a second day if you choose to linger.

Before You Drive This Route
The Boyle & Lough Key Forest Park is 46km and about 1 hour of driving, though 1 day is the honest figure once you factor in the stops. Visitors who have never driven on the left should start with driving on the left in Ireland; the Irish roundabout rules guide covers the other thing that catches people out. Travelling with children, our family road trip guide has the stops and timings that keep a day like this civil. Automatic or manual is the decision that catches most visitors out — manual versus automatic has the honest answer for Irish roads. More drives in the same corner of the country are on the County Roscommon page, and the Athlone & Shannon Heritage pairs naturally with this one.
