The LGBT crowd is welcomed in many European capitals, but only London has a Gay Tourist Office staffed with English-speaking officials who can give free advice on local sights. It's located in the Soho district on the corner of Frith Street and Old Compton Street.
For a do-it-yourself itinerary, try this: Start off on Saturday morning with the London of Oscar Wilde walking tour, led by London Walks. You'll retrace the footsteps of the famous gay playwright around his favorite Victorian London haunts. Afterward, head to the watering hole City of Quebec by Marble Arch. The pub, founded in 1946, has a bias toward male silver foxes.
In the evening, flounce into the city's vibrant cabaret scene. The 50-plus LGBT crowd will feel especially at home at the Royal Vauxhall Tavern, which has lured people to drag shows and other cabaret performances since the 1940s.
