Ah, staycations.

Sick of hearing about them yet? You better not be, because as of last week, the government announced that not only would a staycation tax rebate be introduced later on this year (from October, unfortunately for us), but that the majority of visitor heritage sites are now free to the public.  Yes, free. No money needed. Except to get there, obviously. Here's five that we're absolutely dying to check out this year. 1. The Burren, Co Clare  Let's kick off with a classic, shall we? The Burren National Park contains all the major habitats of the region, limestone pavement, hazel scrub, deciduous woodland, wetlands and species-rich grassland. The heritage site has also got a decent amount of flowers blooming across its landscape with little numbers from from the Arctic, Alpine and Mediterranean regions, all growing together. There are 7 marked trails of varying length and difficulty through the park, meaning that you could spend an entire day here and still not to experience all of its glory. 2. Céide Fields, Co Mayo Beneath the bog lands of North Mayo lies the Céide Fields -  the most extensive Stone Age monument in the world. Comprised of field systems, dwelling areas and megalithic tombs, the stone walled fields are almost 6,000 years old, making them the oldest in the world... that we know of. The fields are covered by a natural blanket bog with its own unique vegetation and wildlife, and the site itself is located beside some of the most spectacular cliffs and rock formations in Ireland. Not a bad shout at all, this summer. 3. Carrowmore Megalithic Cemetery, Co Sligo  The largest cemetery of megalithic tombs in Ireland, Carrowmore is absolutely worth adding to your staycation activity list this summer. The cemetery is among the country's oldest, with monuments ranging from 5,000 to 5,800 years old (so pretty old, yeah?) Archaeologists have recorded over 60 tombs of which 30 are visible on site. Divine was a casual wander, nonetheless. 4. Charles Fort, Co Cork  One of the largest military installations in the country, Charles Fort has been associated with some of the most momentous events in Irish history. We're talking the Williamite War of 1689-91, the Civil War 1922-23, and lots of other less important ones, probably. Charles Fort was declared a National Monument in 1973, and now it - like everything else on this list - is available to visit for free. Enjoy it, yeah? 5. Trim Castle, Co Meath The largest Anglo-Norman castle in Ireland (yes, honestly), Trim Castle was constructed over a thirty-year period by Hugh de Lacy and his son Walter. Construction of the massive three storied central keep started around 1176 on the site of an earlier wooden fortress, meaning that you're not just going to get a glorious structure to ogle over when you visit - you're also going to get a lot of history.
