The Muckross Park Hotel is one of oldest hotels in Killarney. It opened its doors as The Herbert Arms in 1795 and was part of the original Muckross House Estate. In August 1861 Queen Victoria visited Killarney and stayed at Muckross House just across the road from the hotel and she took lunch in the hotel on Wednesday 28th August. Other past guests include George Bernard Shaw who spent the summer of 1923 in the hotel writing Pygmalion (My Fair Lady).

The current owners Bill Cullen and Jackie Lavin took over the hotel in 1990 and over the years added facilities such as the multi-award winning Molly Darcy's Irish Pub. Their ongoing vision continues to be realised with the recent opening of the newly refurbished and rebuilt Muckross Park Hotel with 69 fabulous new guestrooms and one of Irelands most exclusive 'health and well being' centres - the gothic inspired Cloisters Spa.
