This month-long river festival celebrates the Thames along its full 42‑mile length with art installations, boat rides, guided walks, film screenings, and much more.
Many events during Totally Thames are free; however, there are some ticketed experiences such as “Footsteps of Mudlarks”, which costs around £25. Activities take place across various locations, from Greenwich and Lambeth to Kingston and Docklands. Since dates and times vary, it’s best to consult the Thames Festival Trust calendar in advance.

This annual event invites the public into London’s iconic, and usually private, buildings. Entry is free, but we suggest booking in advance for many popular venues.
4. London Fashion Week (18–22 September)
One of the “Big Four” global fashion events, LFW showcases runway shows across popular London venues. This is typically an “industry access” event; however, some public exhibitions or pop-ups are available.
