There’s always something to do in the bustling city of London. Here are 10 activities you shouldn’t miss in May.

Attend a festival with a giant upside-down cow

Consider checking out the Udderbelly Festival, if only to say that you’ve attended a festival with an upside-down, inflatable purple cow. The event runs until July 17 and brings live music, circus acts and comedy performances to Southbank Centre. The festival’s sister event, London Wonderground, runs until September 25 and extends the fun with even more circus acts, fairground rides and cabaret performances.

Check out photographs by emerging photographers

Venture down to The Crypt on Borough High Street from May 19 to 21 to catch some amazing photographic talent at the London Photo Festival. Works from emerging photographers will be displayed and available for purchase, and will be centered around this year’s theme: the four elements.

Drink wine during London Wine Week

London Wine Week returns for a third year in May, offering the perfect excuse to drink wine at different bars across the city. From May 23 to 29, your wristband will get you a wine flight for £5 at any of the 125 participating restaurants and bars. There will also be tastings, pop-ups and dinner events throughout the week.

End your day with some truffles and prosecco

Trufflesecco, which opened on Camden High Street last month, focuses on two of our favourite things: truffles and prosecco. Owned by two sisters, the bar has eight different kinds of prosecco and a small menu that includes truffle pasta, meat and cheese platters, and more.

Get your Harry Potter fix during a Warner Bros. Studio Tour

Even if you didn’t manage to snag tickets to the sold out Harry Potter and the Cursed Child theatre production that starts in June, you can still have a magical time in London. Visit the studio where the popular film series was shot for more than a decade to tour some of the soundstages and sets and check out costumes and props. Be sure to visit the backlot to get a cup of Butterbeer before you leave.

Learn more about one of the greatest English rock bands of all time

Exhibitionism, a new exhibit examining the career of The Rolling Stones, opened at the Saatchi Gallery in April. This is the first time an international exhibition has focused on the famous English rockers, and it features more than 500 pieces of The Rolling Stones’ history across the two floors of the gallery. Gain a new perspective on the band as you take in the costumes, instruments and rare video footage.

Smell some blooms at the RHS Chelsea Flower Show

This annual flower show, held at the Royal Hospital Chelsea, attracts more than 150,000 people to view the beautiful gardens and learn about the latest gardening designs and trends. During this year’s show (May 24 to 28), be sure to check out designer Phillip Johnson’s poppy display, which features almost 300,000 crocheted poppies spread across 21,000 square feet of the hospital grounds.

Take in an outdoor film on the rooftop of a London building

The Rooftop Film Club opens for its 2016 season this month, and will screen a range of newer, older and cult films at twilight on the roofs of four different buildings in London. Upcoming film screenings include Psycho at the Bussey Building and Ferris Bueller’s Day Off at Queen of Hoxton. Deck or director’s chairs are provided and there’s a rooftop bar and concession stand.

Watch a play by England’s most celebrated playwright

Last month marked the 400th anniversary of famed English playwright Shakespeare’s death, but the Globe Theatre will be holding events throughout the year to mark the milestone. Of course, you can also take in one of his plays at the open-air theatre—performances of A Midsummer Night’s Dream are on now, while The Taming of The Shrew starts May 13.

Visit a London museum at night

London is full of fascinating museums and historical spaces, and twice a year, you can check them out after hours during Museums at Night. From May 11 to 14 (the event also takes place in October) you can take evening tours of regular exhibits at institutions like the Natural History Museum, Tate Modern and the British Library. Each venue will also put on events like special talks, performances and exhibits.
