Many people staying on Holy Island do so short term whilst waiting for the ferries to Dublin Port. As such the largest hotels (Travelodge and Premier Inn) are located close to the A5/A55 roads. Centred in Holyhead but dotted around the island (especially Trearddur Bay and Rhoscolyn) are quite a number of smaller bed and breakfast hotels and caravan parks for people who may wish to stay longer. Attractions in the area include South Stack Lighthouse and the RSPB reserve close by, the Breakwater Country Park, the RNLI museum and walks up Holyhead Mountain.
