How To Travel Around Ireland

I’m planning a trip to Ireland and I’m looking for advice on how to travel around the country on a budget. I’m hoping to visit as many places as possible, but I’m trying to be mindful of my budget. I’m wondering if anyone has any tips or advice for how to make the most of my trip without breaking the bank. I’m open to suggestions on how to save money on flights, accommodation and transport, as well as any other tips on how to get the most out of my trip while still being mindful of my budget. Any advice would be greatly appreciated!
