I'll be honest – I've always been drawn to heights, and when I first heard about Sky Garden Londres, I knew it had to be on my list. Located on the top three floors of 20 Fenchurch Street, this free public garden offers something quite different from London's usual viewing spots.

The building itself, designed by Uruguayan architect Rafael Viñoly in 2004, has that distinctive shape that grows wider as it rises. Locals call it the Walkie-Talkie, and once you see it, you'll understand why. Getting inside requires advance booking – spaces are limited and you can reserve up to three weeks ahead through their website.

What strikes you first isn't necessarily the garden itself, though the landscaping by Gillespies is thoughtful. They've chosen drought-resistant Mediterranean and South African plants that work well in this elevated glass environment. You'll spot African Lily, Red Hot Poker, and Bird of Paradise among the greenery, plus fragrant French Lavender that adds a nice touch.

But let's be real – most people come for those 360-degree views across London's skyline. From the observation decks and open-air terrace, the city spreads out beneath you in all directions. Looking south, the Thames winds between buildings with Tower Bridge standing proud in the distance. Turn west and you'll catch the dome of St. Paul's Cathedral, with the London Eye and Houses of Parliament beyond.

The space combines the landscaped terraces with bars and restaurants, creating a social atmosphere that feels relaxed rather than touristy. It's genuinely popular with locals, which always feels like a good sign when you visit Sky Garden.

Free admission is obviously appealing, though the advance booking requirement means you can't just show up on impulse. The plants do flourish year-round as promised, maintaining color even in London's grayer months.
