Parks, rooftop bars, outdoor cinemas – where are the best places to head in London when it’s sunny?

With millions of pictures being shared, Instagram has the answers.

The capital is the most Instagrammed city in the world, with most pictures posted when the sun is shining, so it’s a great measure of what’s hot when it’s hot outside.

With the weather warming up and summer just around the corner, Love Home Swap has done some digging on the social site to find the most popular places to go for enjoying an ice cream, sipping on a cool drink or just generally soaking up the sun.

Here are the top 20 places, with figures showing many posts there have been on Instagram for each one:
