The London Eye holds 32 capsules. Visits last for one rotation, which takes about 30 minutes, and during that time visitors rise to a peak height of 443 ft. From there, it’s possible to see up to 25 miles away. Each of the 10-ton capsules represents one of the London Boroughs, and holds up to 25 people, who are free to walk around inside the capsule, though seating is provided.
