A visit to St Paul's is one of London's heavyweight experiences. Expect soaring domes, intricate mosaics, and the famous Whispering Gallery where voices carry across the 30-metre void. Climbing the 500+ steps to the Golden Gallery rewards you with sweeping views over the city, while the crypt holds monuments to Wellington, Nelson and the Duke of York. A standard visit takes 90 minutes to two hours; a guided tour adds context on the building's turbulent history and Wren's engineering without feeling rushed. It's busy but the sheer scale absorbs the crowds better than many smaller churches.
Best time is spring or autumn on a weekday morning right after opening. Summer weekends get packed and the dome can feel stuffy. Expect to pay around £20-£28 for a standard ticket; guided tours or audio guides add another £5-£10. Combo tickets with the nearby Tower or a river boat sometimes bring the per-site cost down.
Honest tip: do the full climb if your knees allow — the views are genuinely better than from the London Eye and far less touristy. Skip the crypt on a first visit unless you're into tombs; the main space and galleries deliver the real punch. Go early, rent the audio guide only if you like facts on demand, and sit in the nave for ten quiet minutes — that's when the building really works its magic.
