Festivals come in all shapes and sizes, but one thing's for certain: all the best ones can be found in the heart of summer. The city has so many for you to pick, from dancing in a field with spectacular music to food and wine fiestas. Whatever one you fancy, you are bound to find something you love in our recommended list of London summer festivals for 2026.




The Tacover Taco & Tequila Festival 2026

@ Richmond Athletic Ground on Friday 14th August 2026 and 2 other dates

On the back of selling out seven events in the past three years, The Tacover Taco Tequila Festival is back and bigger than ever. Set to be Europe's largest Mexican food and drinks festival, it's bringing over 40 top-tier traders to Richmond Athletic Ground.

On top of fantastic food and banging booze, there'll be mariachi bands, luchadores, folk dancers, tortilla slapping and hot taco challenges. Believe it or not, all this can be yours from just £1.10 for kids and £8.80 for adults.

Lost Oasis

@ Courtyard at St Martin-In-The-Fields on Various dates from Friday 7th August 2026

While muddy fields outside the M25 have their charm, one of the best summer festivals in London 2026 is actually happening right in Zone 1. Lost Oasis brings the festival energy to St Martin-In-The-Fields with a month-long celebration of music, culture, and world-class gastronomy.

This urban festival pulls out all the stops when it comes to production. Between exploring the stunning landscape design, festival-goers can sample incredible chef residencies, pour fresh pints directly from a giant sculptural cider tree, or catch exclusive summer screenings.
