Travel: Greece is the word for a fab destination as restrictions lift and country announces borders open from May 14 by Sarah Marshall Updated: March 17, 2021, 2:06 pm Corfu, Greece. Nearly four million Brits go to Greece every year, which means the UK is one of its most important tourism markets. All arrivals have to present a negative Covid test taken within a 72-hour window, while arrivals from the UK have to undergo a rapid test on arrival as well. A firm favourite with travellers, Greece is set to become a prime holiday destination this summer, after its government announced it would welcome all vaccinated tourists from May.
