Hi Heike,
It's good to hear that you'll be spending time in Tralee! It seems that left luggage facilities are available at
Tralee (Casement) Station. I would recommend that you get in touch with the Station directly for more information on their services.
Additionally, accommodation providers in the area may also offer this service. It's worth contacting local hotels to check if they would be able to facilitate this for you. You can learn more about
accommodation here.
Regards,
Eoin
