The wheel never stops for you to board. The London Eye turns at about 26 centimetres a second, slower than a toddler walks, so you step into a moving glass capsule and step out half an hour later having made one full circle 135 metres above the Thames. It went up as a temporary millennium celebration in 2000 and was the tallest observation wheel on earth until China's Star of Nanchang overtook it in 2006; Londoners then refused to let it come down, and it became the UK's most visited paid attraction, with over three million riders a year. Taller wheels exist now, but it remains the world's tallest cantilevered one, held from one side only, like a colossal bicycle wheel bolted to a single fork. There are 32 capsules of 25 people each, numbered 1 to 33 because 13 was quietly skipped. The view is the whole point: the Palace of Westminster and Big Ben directly below you on the opposite bank, Buckingham Palace in its green, the City towers to the east and, on a genuinely clear day, roughly 40 kilometres out to Windsor Castle. Capsules are enclosed and climate-controlled with a bench in the middle, and the whole route is step-free with pushchairs and wheelchairs welcome aboard, which makes this friendlier to families with small children than most of London's big sights. Be honest with yourself about value: it is a short experience for the money. Adult tickets start at GBP 29 on the official site, rising with demand, and reach GBP 39 at the ticket office on the day; children aged 2 to 15 from GBP 26, under-twos free. In July and August standard ticket holders queue 30 to 60 minutes before boarding, so either take the first slot of the morning or pay the fast-track premium. Sunset slots sell out days ahead, and strong wind can halt the wheel at short notice, with a rebooking or refund. Combination tickets with the SEA LIFE aquarium next door or Madame Tussauds cut the total if those were on your list anyway. It runs daily from 10:00 to 20:30 in summer, at weekends and in school holidays, and from 11:00 to 18:00 the rest of the year, with last boarding 30 to 45 minutes before closing. It shuts for a stretch of January for maintenance (usually a couple of weeks, so check the dates before you travel) and on Christmas Day. Waterloo station (Jubilee, Northern and Bakerloo lines) is a five-minute walk; from Westminster (Jubilee, Circle, District) the ten-minute walk across Westminster Bridge gives you the classic photograph of wheel and Parliament in one frame. In winter London is dark before 16:30, and a post-sunset slot buys you a lit-up city instead of grey haze.

Big Ben and Parliament sit directly across the river, Buckingham Palace in its greenery, and on a clear day the view runs some 40 kilometres to Windsor.
The best light for photographs and the first slot to sell out; book days ahead in summer, and in midwinter any slot after 16:00 gives you the city lit up.

Trafalgar SquareFour bronze lions guard a column some 52 metres tall, and on top of it a one-arm10 minutes walk4.5The Shard is far higher (its viewing floors sit around 244 metres), your time up there is unlimited, and the price is similar. The Eye, though, puts Westminster and Big Ben close and low enough that the landmarks are actually legible, and children love the ride itself. Families with kids: pick the Eye. If you want the full skyline in photographs and time to linger, pick The Shard. Paying for both is unnecessary.
The capsules are enclosed and climate-controlled, so you stay dry, but the view is what you are paying for and a low winter mist erases it entirely. Watch the forecast and book a clear day even if it is cold; high wind can stop the wheel altogether, with a rebooking or refund. If your only free day is a wet one, spend the money elsewhere.
