The icons of the skyline — on the river, above the Thames and out over the rooftops.
From free rooftop gardens to open-air skydecks, London stacks more high viewpoints than almost any city in Europe. Here's how to pick the right one.
Rooftop gardens and galleries you can visit for nothing, alongside the big ticketed skydecks.
Lifts to the top at the Shard, Horizon 22, Sky Garden and Lift 109 for level access to the view.
Choose a glass-walled gallery for any weather or an exposed deck for the wind in your hair.
We flag the decks with golden-hour and after-dark tickets so you catch the city lighting up.
Every viewpoint mapped to what it overlooks — the river, the City cluster or the whole basin.
Slides, cable cars and interactive decks that keep younger visitors as hooked as the view.
Book the last slot before sunset for the best colour.
Evening tickets trade the horizon for a sea of lights.
On a crisp morning you can see up to 40 miles out.
Weather, budget and timing change which deck is worth the trip. Tell us what you're after — a free rooftop, a sunset slot, a step-free lift or somewhere to take the kids — and we'll point you to the best match.
Every listing gives you the viewing height, the nearest Underground or DLR station and exactly what sits on the horizon.
Beyond the City towers — a chimney lift, a rooftop garden, a roof-walk and a slide-topped sculpture.

DetailsReal notes from people who've done the climb.
Sky Garden, Horizon 22, The Garden at 120 and the One New Change roof terrace are all free — Sky Garden and Horizon 22 need a booked timed slot, while the other two are walk-in. Primrose Hill is free and open around the clock.
The View from The Shard, with indoor galleries around 244 m and an open-air Skydeck near 245 m. Horizon 22's free gallery at 254 m sits higher off the ground but is enclosed; the Shard keeps the title for an open-air view.
For the free galleries, yes — Sky Garden and Horizon 22 release timed tickets a few weeks ahead and they go quickly. Ticketed decks like the Shard, Lift 109 and Up at The O2 are best pre-booked, especially for sunset slots.
The Shard, Horizon 22, Sky Garden, Lift 109, The Garden at 120 and Westminster Cathedral's tower all reach the view by lift. The Monument and St Paul's Golden Gallery are stairs-only historic climbs.
Late afternoon into sunset gives you the city in daylight and then lit up — the most popular slots, so book early. Clear mornings after rain offer the longest range, up to about 40 miles from the Shard.
Up at The O2's roof climb, the ArcelorMittal Orbit with its tunnel slide, and the IFS Cloud Cable Car are the most hands-on. Sky Garden is the easiest free option — step-free, indoors and full of plants to explore.
