Climb the O2’s iconic roof to a 52m summit and step inside the UK’s highest snow globe — a 2025–26 winter pop-up that pairs brisk skyline views with a festive photo moment. Practical preview, history, and what to pack for this guided urban climb.
More ways to explore the area's outdoor wonders
You step onto the curved walkway and the city opens around you: the River Thames threads past, cranes punctuate the skyline, and the O2’s white tent skin dips away under your feet. The climb rises steadily to a 52‑metre summit where, for a short winter window, the UK’s highest snow globe waits — falling flakes, cinnamon-sweet air, and a staged photo moment framed by glassy high-rises.
