Fitness & Pool At Castleknock Hotel

*Please note that due to an exciting expansion development at the hotel in 2017, Tonic Leisure Centre, including gym and pool will be closed January 1st 2017 until December 2017. All other ground floor areas remain unaffected by the expansion.

Tonic Day Spa including the relaxation room will remain open from 5-9pm midweek and from 10-7pm weekends for treatments and a temporary gym will be open upstairs during this time for hotel residents. To avoid disappointment we would advise that guests book treatments in advance*
