Llanymynech Rocks Nature Reserve, situated in Shropshire, has been officially named England's best-kept secret, clinching the fourth spot in the UK. SIXT’s new guide encourages holidaymakers to consider domestic destinations, particularly those less-travelled spots that offer unique experiences. They advise exploring these hidden gems by car for flexibility and convenience, as many of these places are off the beaten track. The top three hidden gems were Arbroath Seaton Cliffs in Angus, Scotland, Pwll Deri in Pembrokeshire, Wales, and Taf Fechan Gorge in Merthyr Tydfil, Wales. As summer travel becomes increasingly expensive, more people are considering staying closer to home, making the discovery of domestic hidden gems all the more rewarding.
