Enter a world of secret gardens, as normally restricted and private spaces are open to the public for two days. There are over 200 participating gardens across 27 boroughs in association with The National Trust. Open spaces include conventional hospital gardens, barges, museums, schools, churchyards and even skips!
There are plenty of activities to suit all ages too, including cycle rides, kids events, art, music, self-guided walks, tours and talks. A weekend ticket will only set you back £13 in advance (kids under 12 go free) and gives you access to multiple venues but some spaces are only accessible when you book a free tour. Not all venues are open for the full weekend, so check listings when you plan your itinerary.
