I spotted a DealRush offer the other day for 4-star Lough Rynn castle in Co. Leitrim and then remembered we went there just before Christmas but I never blogged about it due to pure laziness. The deal is only €89 for 2 people for 1 night B&B with early check-in and late check-out (but it's only available for Thursdays, annoyingly).
Anyway, although this is no longer seasonally appropriate, I think these photos still demonstrate the natural beauty you'll see on a walk around the grounds; lakes, forest, a rose garden, a little Summer house/turret overlooking a lake and just general lovely foliage.
Food wise we had a really excellent lunch and a very good dinner (not my favourite of places we've stayed around Ireland but it was good) and again, breakfast was nice. We thought the decor of the restaurant was a bit old fashioned, in an early 90's "we-built-this-part-on" kind of way but the actual house itself was gorgeous: lots of wood, welcoming bar, big open fires, comfy seats and reading nooks and our room was nice and cosy.
If you're looking for a really reasonable break away then check out the DealRush offer HERE.
