Top things to do in London in September

Cruise the Thames at golden hour

  • When: Daily after 5 pm
  • Tags: Outdoors, Tour

September’s low sun turns the Thames bronze—perfect for the Uber Boat hop-on ferry. Tap your Oyster at Westminster Pier, grab the open stern seat, and glide past St Paul’s to Greenwich before dusk. Pair skyline photos with onboard coffee; weekday sailings are quieter.

Recommend experiences:

  • Thames Sightseeing Cruise from Westminster to Greenwich

Wander Kew’s late-summer glasshouses

  • When: Throughout September
  • Tags: Family-friendly,

Explorer Inside Kew Gardens’ steamy Palm House, the riot of orchids offsets any drizzle outside. Outside, the Great Pagoda’s 253 dragons catch warm afternoon light. Arrive at 10 am opening, stroll treetop walkway before coaches roll in, and exit via ferry back to Westminster.

Climb Parliament Hill for city-wide sunset

  • When: Clear evenings
  • Tags: Outdoors,

Explorer Hike ten minutes from Gospel Oak station through Hampstead Heath; by 6 pm the skyline glows. September’s earlier sunset means you’ll be off the hill before dark, with room on the grass to picnic on Borough-market charcuterie.

After-hours at the Tower of London

  • When: Selected Thu–Mon 6:30 pm slots
  • Tags: Cultural experience, Tour

“Ceremony of the Keys” tickets (free, but book a month ahead) let you watch Yeoman Warders lock Britain’s crown jewels at 9:53 pm sharp. The riverside fortress feels eerie minus daytime crowds—dress warm; the stone corridors trap night chill.

Recommend experiences:

  • Tower of London Tickets with Access to the Crown Jewels

Street-art safari in Shoreditch

  • When: Weekday mornings
  • Tags: Cultural experience, Explorer

Start on Brick Lane before the bagel queue, then follow Rivington’s alleys for fresh Banksy-adjacent murals. September rain showers revive paint colors; pack a phone gimbal for filming artists at work. Finish with Bangladeshi curry lunch by 1 pm.

Picnic among Richmond Park’s deer

  • When: Weekends, 11 am–4 pm
  • Tags: Family-friendly, Outdoors

Dangle feet over Pembroke Lodge meadow while red deer graze nearby—just keep 50 ft distance. Bring bakery pastries and thermos tea; the rookery trees are already edging bronze. Bus 371 from Richmond station drops you at the park gate.

Tate Modern’s Turbine Hall commission

  • When: Daily, 10 am–6 pm
  • Tags: Cultural experience, Season-only

A new mega-installation debuts each autumn; September visitors see it first. Pop in via Millennium Bridge, linger 20 minutes, then ride to the free tenth-floor viewing deck for skyline shots—all without spending a pound.

West End matinee & backstage pint

  • When: Tue–Thu 2:30 pm shows
  • Tags: Family-friendly, Cultural experience

Matinees dodge evening tour groups. Book discounted seats online the night before, catch “Matilda” or “Hamilton,” then nip behind Drury Lane to the subterranean Nell of Old Drury pub for a post-show ale.

Recommend experiences:

  • Matilda the Musical
  • Hamilton
