If you’re travelling to resorts like Sharm el Sheikh, Taba, Dahab and Nuweiba for up to 15 days, you’ll be given a free entry permission stamp on arrival. But if you intend to travel outside of these areas, or stay for longer than 15 days, you’ll need a visa. You can get a visa in advance from the Egypt e-visa portal, or on arrival, for around $25 US dollars - it’ll be valid for three months. For more information on entry requirements to Egypt, check the FCO website.
