Why you should go: English Heritage membership gives you access to more than 400 world-famous prehistoric monuments, abbeys, and palaces—Dover Castle, Hadrian's Wall, and Stonehenge, to name a few. Membership lasts for a year, so you’ve ample time to explore.

What's the big deal? Travelzoo members can snap up an annual pass for £51.75. Senior, student, joint, and family options are also available, and there are additional perks like a handbook and magazines to enrich your visits.

Travelzoo tip: This offer is right on time for the King's coronation, when English Heritage will plant wildflower meadows across 100 of their sites and run special events and exhibitions to celebrate.
