How to Book the Ultimate Clock Tower Climb
Updated August 2025
The iconic chime of Big Ben is one of the most recognizable sounds in the world, echoing across London since 1859 from the Elizabeth Tower. Stepping inside the Tower offers a rare chance to explore its inner workings—the clock machinery, the belfry housing the Great Bell, and panoramic views through the four clock dials. But because this is a working part of Parliament and involves 334 steep, narrow spiral steps, planning—and fitness—are essential.

Where to Book:
If climbing through history to the belfry is on your bucket list, make booking your tour a top priority. Tickets are released online three months in advance, every second Wednesday of the month, promptly at 10:00 a.m.—and they sell out fast. You can book up to eight tickets per person via the official UK Parliament (See Tickets) portal.
From 1 April 2025, ticket prices are £35 for adults and £20 for children aged 11–17. These include the 90-minute guided climb through the Tower. UK residents can also request free tickets through their local Member of Parliament, though availability is very limited.
Given the historic architecture and steep spiral staircase, the tour is not suitable for everyone. It requires solid mobility, strength, and balanced coordination. Those with recent surgeries, back or joint issues, respiratory or heart conditions, vertigo, or concerns with confined or high spaces should avoid it. Assistive devices and assistance dogs are not permitted, and the climb must be completed within 90 minutes without breaks. Ear defenders are provided due to the loud bell and machinery. Hearing loops are available on request upon arrival
On tour day, arrive at Cromwell Green at least 30 minutes prior to your scheduled time. Expect airport-style security and mandatory lockers for belongings—especially since photography inside is prohibited. The visit lasts about 1 hour and 45 minutes, which includes time to deposit and reclaim your items and the 90-minute climb-and-discover experience.
Wear comfortable, flat-soled, fully closed shoes—rubber-gripped is best. Flip-flops, sandals, high heels, or bare feet are not allowed. The Tower can be chilly and windy at the top, so dress in layers and bring a light jacket if needed.
After the climb, you’re free to explore medieval Westminster Hall, and rest with refreshments at the nearby Jubilee Café, or browse official souvenirs in the adjacent shop.
Accessibility remains an issue: there is no step-free access, so wheelchair users and those with limited mobility cannot participate. However, there are plenty of accessible viewpoints around Westminster—Westminster Bridge and Parliament Square offer fantastic front-row views of the tower.
To conquer Big Ben: book early (3 months ahead), come prepared physically, arrive early, and follow the safety guidelines. Climbing the Tower is more than a sight – it’s a heartbeat of London’s history, up close and unforgettable.
